Scleredema is a rare skin condition that causes the skin to become thick, firm, and hard to pinch, most often on the neck, shoulders, upper back, and face. The early symptoms of scleredema can include a feeling of tight skin and reduced ease of movement, and some people also notice stiffness in nearby joints. Scleredema can affect children or adults, but it is often seen after an infection, in people living with diabetes, or alongside certain blood disorders, and it may last weeks, months, or become long term. Not everyone will have the same experience. Scleredema is usually not life-threatening, and treatment focuses on the cause when one is found and on easing symptoms with options such as managing blood sugar, light-based treatment, physical therapy, and other skin-directed care.
How many people live with Scleredema?
Scleredema is so rare that a reliable count of how many people are living with it worldwide or in the United States is not consistently reported. Rare-disease references describe it as a very rare skin-thickening condition, but they do not give a firm global or U.S. total (Orphanet, 2024; Genetic and Rare Diseases Information Center, 2024).
Overview
ScleredemaSymptoms
Scleredema causes areas of skin to become thick, hard, and tight, most often on the neck, shoulders, upper back, or face. Many living with scleredema notice stiffness and reduced movement. Early symptoms of scleredema can make lifting your arms or turning your head harder.
Outlook and prognosis
Scleredema often improves slowly, especially when it follows an infection, but skin thickening can last months or years. When linked to diabetes or a blood disorder, scleredema may be more persistent and can limit shoulder, neck, or chest movement.
Causes and risk factors
Scleredema often develops after a streptococcal infection, with diabetes, or alongside a blood protein disorder. Risk is higher in people with long-standing diabetes and obesity. The exact cause is unclear, and lifestyle is not usually a direct cause.
Genetic influences
Genetics are not thought to play a major role in Scleredema for most people. Scleredema is usually linked to diabetes, infections, or blood disorders rather than inherited gene changes.
Diagnosis
Scleredema is diagnosed with a skin exam and your medical history. Doctors may use a skin biopsy to confirm it and rule out similar conditions. Blood tests can help look for diabetes, infection, or blood disorders.
Treatment and drugs
Treatment for scleredema focuses on easing skin thickening and stiffness, often with light therapy, physical therapy, and careful management of related diabetes or infection. Some people with scleredema may also need medicines to calm inflammation.
Symptoms
Scleredema often shows up as skin on the neck, shoulders, or upper back becoming unusually thick, firm, and hard to pinch or move. Early on, this might look like mild puffiness or stiffness that does not go away the way ordinary swelling does. Symptoms vary from person to person and can change over time. In some people, scleredema stays mostly in the skin, while in others it can make movement, swallowing, or breathing feel harder.
The skin often becomes firm, dense, and hard to pinch, especially over the back of the neck, shoulders, and upper back. It may feel almost woody or boardlike rather than soft and flexible.
Many people with scleredema notice a tight, stretched feeling even without much pain. Collars, backpack straps, or fitted shirts may feel less comfortable because the skin does not move as easily.
Thickened skin can make it harder to turn the neck, lift the arms, or bend the upper body. Everyday tasks like reaching a high shelf, washing your hair, or checking over your shoulder can take more effort.
Early symptoms of scleredema can include persistent puffiness or a heavy, swollen feeling before the skin seems clearly thickened. Unlike usual swelling, pressing on the area often does not leave much of a dent.
How people usually first notice Scleredema?
People usually first notice scleredema when the skin on the back of the neck, upper back, shoulders, or face starts to feel unusually firm, thick, or tight, almost as if it is becoming less flexible over time. For many living with scleredema, this can mean trouble turning the head, raising the arms, or moving comfortably, and the change often appears gradually after an infection, alongside diabetes, or without a clear trigger. Because the first signs of scleredema can look like simple skin swelling or stiffness at first, it is often a doctor’s exam that connects those early changes to the condition.
Types of Scleredema
Scleredema can affect daily life in different ways depending on which form someone has. The main types of scleredema are usually grouped by what seems to trigger the skin changes, and those differences can affect how long symptoms last and who is most often affected. Symptoms don’t always look the same for everyone. When people ask about the types of scleredema, doctors usually mean three well-recognized forms.
Type 1
This form often starts suddenly after an infection, most often in children or young adults. The skin on the neck, shoulders, face, or upper back may become firm, thick, and hard to pinch, but it often improves over months to a few years.
Type 2
This form is linked with certain blood protein disorders and usually develops more slowly. Many living with scleredema type 2 have skin thickening that lasts longer and may be more persistent than in the post-infection form.
Type 3
This form, often called scleredema diabeticorum, is most often seen in people with diabetes, especially when blood sugar has been hard to manage over time. The skin thickening usually affects the upper back, neck, and shoulders and may limit movement, such as turning the head or lifting the arms comfortably.
Can I slow down the onset of symptoms?
Probably not in a reliable way: there is no proven lifestyle change or treatment that clearly delays the start of scleredema symptoms. For the type linked with diabetes, keeping blood sugar in a healthy range and managing weight may help lower risk or slow worsening, but research is limited, and these steps have not been shown to prevent scleredema; there is also no well-established preventive medicine or routine screening for people without symptoms. Even so, staying on top of diabetes care and getting checked early if your skin starts to feel tight, thick, or hard can still help you get support sooner.
What genetics can tell you about symptoms
For people living with scleredema, genetics usually does not give clear answers about which symptoms will happen, how severe they will be, or when they will start. Unlike some inherited skin conditions, scleredema is most often linked to other health issues such as diabetes, a recent infection, or certain blood disorders rather than to a specific gene change passed through families. That said, doctors may still think about genetic causes if skin thickening looks unusual or starts very early, because a few rare inherited disorders can cause similar symptoms.
Causes and risk factors
Scleredema can start after a recent infection, especially strep throat, and it can also occur in people with long-term diabetes. It may also be linked to blood conditions that make abnormal proteins, such as monoclonal gammopathy. Poor blood sugar control and higher body weight can raise the risk of the diabetes-related form of scleredema. Not everyone with the same risk develops the condition. No clear inherited genetic cause is known, but immune system changes and other health conditions may affect who develops scleredema.
What are the most common causes or risk factors?
Scleredema usually is not inherited, and there is no single known gene cause. The most common risk factors are long-standing diabetes, especially when blood sugar has been high for years, being overweight or obese, and having it begin after an infection such as strep throat. In some adults, it is also linked to blood conditions that make an abnormal protein, sometimes called monoclonal gammopathy.
Environmental and biological risk factors
Scleredema is a rare skin condition in which the skin becomes thick, firm, and hard to pinch, often across the neck, shoulders, and upper back. Doctors often group risks into internal (biological) and external (environmental). For scleredema, most known risk factors are biological, while the main outside-body trigger is a recent infection.
Longstanding diabetes, especially when blood sugar stays high, is one of the strongest risk factors for scleredema. Many people with this pattern develop skin thickening gradually over time rather than all at once.
Some cases of scleredema begin after an infection, most often a throat infection caused by streptococcal bacteria. The skin changes may appear days to weeks later, even after the fever or sore throat has passed.
Scleredema can also be linked with abnormal blood proteins, sometimes called a monoclonal gammopathy. In a smaller number of people, it appears alongside plasma cell disorders such as multiple myeloma.
Age can influence which type of scleredema is more likely. Post-infection scleredema is seen more often in children and younger adults, while diabetes-related scleredema is more common in middle age.
Genetic risk factors
For most people living with scleredema, genetics do not provide a clear answer. Right now, the genetic causes of scleredema are not well defined, and most cases are not known to run strongly in families. Risk is not destiny—it varies widely between individuals. A few inherited tendencies, especially those linked to diabetes in some cases, may play an indirect part.
No single gene: Researchers have not identified one gene change that reliably causes scleredema. For most people, genetic testing does not reveal a specific inherited cause.
Usually sporadic: Scleredema usually appears in one person in a family rather than across several generations. That pattern makes a strong inherited form unlikely in most cases.
Family history: Reports of scleredema affecting several relatives are very uncommon. If skin thickening seems to run in a family, doctors may also look for other inherited skin or connective tissue conditions that can look similar.
Diabetes tendency: In the diabetes-related form of scleredema, an inherited tendency to diabetes may indirectly raise the chance of developing it. This does not mean there is a known scleredema gene, but it can help explain some family patterns.
Testing limits: The genetic risk factors for scleredema are still too unclear for routine genetic screening to be standard care. Testing is usually considered only when the overall picture suggests a different inherited condition.
Lifestyle risk factors
Lifestyle habits are not the main cause of scleredema, but they can matter in people who have the diabetes-associated form or are at risk of worse skin thickening and reduced mobility. In practice, the most relevant lifestyle risk factors for scleredema are the ones that worsen blood sugar control, weight gain, and physical deconditioning. These factors may increase the chance that symptoms become more persistent or harder to manage.
A diet high in refined carbohydrates, sugary drinks, and excess calories can worsen insulin resistance and blood sugar control. In diabetes-associated scleredema, this may contribute to more persistent skin thickening and stiffness.
Too little physical activity can worsen insulin resistance and promote weight gain. It can also reduce shoulder, neck, and back mobility, which may make scleredema-related tightness more limiting.
Overweight and obesity are closely linked to poorer glucose control and chronic low-grade inflammation. In people with scleredema, extra weight may increase mechanical discomfort and make movement restriction more noticeable.
Skipping glucose monitoring, inconsistent meals, or poor adherence to a diabetes-friendly routine can lead to prolonged high blood sugar. This is one of the most important ways how lifestyle affects scleredema in the diabetes-associated form.
Risk prevention
Scleredema cannot always be prevented, because it can appear after an infection, alongside diabetes, or with certain blood disorders. For many, prevention is really about lowering the chance of triggers and reducing the risk of complications rather than fully avoiding scleredema itself. Prevention is about lowering risk, not eliminating it completely. If you are worried about scleredema risk factors or early symptoms of scleredema, regular medical care can help catch related problems sooner.
Scleredema is more likely in people with long-standing or poorly controlled diabetes, especially when blood sugar stays high over time. Keeping glucose in your target range may help lower risk and can also reduce worsening if scleredema develops.
Some cases of scleredema appear after bacterial throat or skin infections. Getting evaluated and treated promptly for suspected infections may reduce one important trigger.
Ongoing medical visits can uncover diabetes, prediabetes, or blood conditions linked with scleredema before they cause more harm. Prevention works best when combined with regular check-ups.
Reaching a healthier weight and staying physically active can support better blood sugar control and overall skin and joint mobility. For many living with scleredema, this may also help limit stiffness in the neck, shoulders, and upper back.
Can you prevent Scleredema?
There is no sure way to prevent scleredema, and in many people it cannot be fully prevented. In some cases, keeping diabetes well controlled and getting infections treated promptly may help lower the risk, especially when scleredema develops after high blood sugar or an infection. Even then, prevention is not guaranteed because the condition does not have one single clear cause.
Transmission
Scleredema is not contagious, so it does not spread from one person to another through touch, coughing, sex, blood, or everyday contact. Even when scleredema starts after an infection such as a sore throat, the skin condition itself is not infectious and cannot be passed on to family members, coworkers, or close contacts.
For most people living with scleredema, there is also no clear evidence that it is inherited from a parent, so questions about how scleredema is inherited usually have a reassuring answer: it is generally not considered a genetic condition. Instead, scleredema is most often linked to the body’s response after an infection or to other health problems, such as diabetes, rather than any form of transfer.
When to test your genes
For scleredema, genetic testing is usually not part of early detection or routine care, because this condition is generally not inherited. What matters more is checking for common linked causes such as diabetes, a recent infection, or a blood protein disorder. If your doctor suspects a different inherited skin-thickening condition, genetic testing may help clarify the diagnosis.
Diagnosis
Scleredema is usually diagnosed after a doctor notices a typical pattern of skin thickening, often across the back of the neck, shoulders, upper back, or face. The skin may feel firm or tight, and for many this can mean trouble turning the neck, raising the arms, or finding shirts and jackets less comfortable. It’s natural to worry when symptoms don’t have a clear explanation. The diagnosis of scleredema is based mainly on the exam, with tests used to confirm the picture and look for related conditions.
Doctors look for firm, woody skin thickening that often affects the upper body in a fairly symmetric way. Unlike some other skin disorders, the fingers are usually not the main area involved, which helps guide the diagnosis.
Your doctor will ask when the skin changes began and whether they followed an infection, diabetes, or another health problem. They also check how much stiffness or limited movement the thickened skin is causing in daily life.
A detailed family and health history can help identify triggers and conditions linked with scleredema. This often includes questions about diabetes, recent throat infections, blood disorders, and medicines.
A small sample of skin may be removed and examined under a microscope if the diagnosis is uncertain. In scleredema, the deeper layer of skin is thickened and shows extra material between collagen bundles, which helps separate it from scleroderma and similar conditions.
How is Scleredema diagnosed?
Scleredema is usually diagnosed with a medical history and a skin exam, where the doctor looks for areas of skin that feel thick, firm, and hard to pinch, often on the neck, shoulders, upper back, or face. They also ask about related health problems, such as diabetes, a recent infection, or certain blood conditions, and may do blood tests to look for these causes. If the diagnosis is not clear, a small skin sample called a biopsy can help confirm it and rule out other skin disorders; genetic testing is not usually part of diagnosis.
Stages of Scleredema
Scleredema does not have defined progression stages. This is because scleredema is usually described by how much and where the skin thickening affects the body, rather than by a set step-by-step pattern over time. Doctors usually start with a conversation about when the skin became firm or tight, along with an exam to check the neck, shoulders, back, and sometimes the face or chest; early symptoms of scleredema can include stiffness, reduced movement, or a heavy feeling in the skin. Diagnosis is often based on the skin changes and medical history, and some people also have tests such as blood work or a small skin sample to help rule out other causes.
Outlook and prognosis
The outlook for scleredema varies by subtype and underlying cause: postinfectious scleredema often improves gradually over months to a few years, whereas diabetic scleredema tends to be chronic and more resistant to treatment. Many people have persistent skin thickening and reduced mobility, but the condition is usually compatible with long-term survival. Prognosis is generally better when the trigger can be treated or resolves, while ongoing poorly controlled diabetes is associated with more persistent disease. Serious internal organ involvement is uncommon, but when present it can worsen function and quality of life. Mortality from scleredema itself is considered rare, and overall risk of death is more often related to associated illnesses, especially diabetes and its complications.
Long-term effects
For many people, scleredema mainly causes long-lasting skin thickening and stiffness, especially over the neck, shoulders, upper back, and chest, which can make everyday movement feel awkward. Long-term effects vary widely, with some people having a milder, fairly stable course and others developing broader problems over time. When the skin stays tight, simple things like turning your head while driving or reaching up to a shelf may become harder. In some cases, deeper tissues or internal organs can be involved, which can affect the long-term effects of scleredema and the overall outlook.
The most common long-term effect is persistent thick, firm skin that does not pinch or move easily. For many living with scleredema, this can last for years and may slowly spread or remain in the same areas.
Tight skin over the shoulders, back, and neck can reduce flexibility and make daily tasks harder. Some people with scleredema notice trouble lifting their arms, bending fully, or turning their head comfortably.
If the chest wall becomes stiff, taking deep breaths can feel more difficult over time. In more severe cases, this can lead to a restrictive breathing pattern, especially during activity.
Rarely, scleredema affects tissues below the skin or involves organs such as the heart, throat, or esophagus. When this happens, long-term problems can include swallowing difficulty, hoarseness, or strain on heart and lung function.
How is it to live with Scleredema?
Living with scleredema often means dealing with skin that becomes thick, firm, and less flexible, most often across the back, neck, shoulders, or face, and that can make everyday things like turning your head, reaching overhead, getting dressed, or finding a comfortable sleeping position more difficult. For many people, there is also the emotional weight of visible skin changes and chronic discomfort, and when the chest is involved, some may notice shortness of breath or reduced stamina. The people around you may need to help with practical tasks and understand that stiffness and fatigue can vary from day to day, but with ongoing medical care, symptom management, and support, many living with scleredema are able to adapt and protect their quality of life.
Treatment and drugs
Scleredema treatment focuses on easing symptoms, improving movement, and managing any related health problems, especially diabetes when it is present. There is no single treatment that works for everyone, so care may include physical therapy to help with stiffness, skin care, and treatment of the underlying condition that may be driving the skin changes. In some cases, doctors may use medicines that calm inflammation or affect the immune system, and some people may be offered light-based treatment, but the response can vary. Not every treatment works the same way for every person, and severe or long-lasting scleredema may need care from a skin specialist and other doctors working together. If you are looking into treatment for scleredema, it helps to know that early care can make day-to-day tasks, like reaching overhead or turning your neck, feel easier.
Can you cure Scleredema?
There is no sure cure for scleredema, although some cases get better on their own, especially when it starts after an infection. Treatment is meant to ease symptoms and improve movement, and may include light treatment for the skin, stretching or physical therapy, and good control of related health problems such as diabetes. For many people with scleredema, the goal is to reduce tightness and make day-to-day activities easier.
Non-drug treatment
Scleredema can make everyday tasks harder when thick, tight skin limits shoulder movement, makes it uncomfortable to turn your neck, or leaves you feeling stiff getting dressed or reaching overhead. Treatment usually focuses on easing stiffness, protecting movement, and helping with breathing or swallowing problems if they happen. Managing this condition often means combining rehabilitation, skin-directed light treatment, and care for related problems such as excess weight or high blood sugar, especially in diabetes-related scleredema.
Stretching and range-of-motion exercises can help keep the shoulders, neck, and upper back moving more freely. For many living with scleredema, this can make daily activities like combing hair or reaching a shelf less difficult.
Occupational therapy helps people with scleredema adapt tasks at home or work when stiffness affects dressing, bathing, or lifting. A therapist may suggest safer body mechanics, pacing, and simple tools that reduce strain.
Light treatment, especially UVA1 phototherapy, may help soften affected skin in some people with scleredema. Not every approach works the same way, and treatment is usually given in a specialist clinic over multiple sessions.
Regular low-impact activity can help maintain flexibility, posture, and overall stamina. Some strategies can slip naturally into your routine—like walking, gentle pool exercise, or supervised strengthening—so movement does not drop further as stiffness builds.
Your genes may have an impact on how drugs work for you
For people living with scleredema, treatment often depends more on the type of scleredema they have, whether diabetes or an infection is part of the picture, and how much the skin is affecting daily life than on their genes. Right now, there is no well-established genetic test that doctors routinely use to predict which medicines for scleredema will work best or cause side effects, although people can still respond differently to treatments such as anti-inflammatory medicines or medicines that calm an overactive immune system. In other words, your genes may play a small part in how your body handles treatment, but for scleredema, this is not yet something that clearly guides care in everyday practice.
Pharmacological treatments
Scleredema can be stubborn, and there is no single medicine that works for everyone. Not everyone responds to the same medication in the same way. When drugs are used, they are usually chosen based on the type of scleredema, how widespread the skin changes are, and whether there is an associated problem such as diabetes, a recent infection, or a blood disorder.
Prednisone and other corticosteroids are sometimes used to try to calm skin inflammation and tightness in scleredema. They may help some people, but benefits are often limited and side effects can be a problem, especially with longer use.
Methotrexate is one of the more commonly tried immune-suppressing medicines when scleredema is widespread or affecting daily movement. Doctors usually monitor blood counts and liver tests during treatment because this drug can cause important side effects.
Cyclosporine may be used when doctors suspect the immune system is driving ongoing skin thickening. It can help in some cases, but kidney function and blood pressure need close follow-up.
Intravenous immunoglobulin, often called IVIG, has been used in some people with severe or hard-to-treat scleredema. In some cases, medicines are combined for better symptom control, and IVIG may be considered alongside other treatments when standard options have not helped enough.
Genetic influences
When skin thickening starts to limit shoulder movement or make it harder to bend, many people with scleredema wonder why it happened. It’s natural to ask whether family history plays a role. Current evidence suggests that scleredema is usually not a strongly inherited condition, and most cases are linked more closely to other triggers such as diabetes, certain infections, or abnormal proteins in the blood than to a single gene passed through a family. That means the genetic causes of scleredema are not well established in the way they are for some other skin disorders. Even so, inherited traits can still matter indirectly, because genes can affect the chance of developing diabetes or immune problems that may be connected with scleredema. If several relatives have similar skin changes or related health issues, your doctor may look more broadly at family history to make sure another inherited condition is not being missed.
Is Scleredema genetic?
Genetics are not thought to play a major role in Scleredema for most people. Scleredema is usually linked to diabetes, infections, or blood disorders rather than inherited gene changes.
Having a genetic risk is not necessarily a diagnosis
Changes in genes, often called genetic variants, are a usual part of human biology and are widely found in the general population. Most of these variants do not directly affect health and are simply part of normal human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some situations, though, a single well-understood variant in a specific gene can be enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
When scleredema causes tight, heavy skin that makes it harder to turn your neck, lift your arms, or move comfortably, treatment is usually chosen based on symptoms and on what may be driving the condition, such as diabetes or a recent infection. Not every difference in response is genetic, but for scleredema there are currently no widely used genetic tests that tell doctors which medicine, light treatment, or immune-based therapy will work best. In practice, doctors usually adjust treatment by watching whether the skin softens, movement improves, and side effects show up. Genes can still influence how your body handles some medications in general, but this kind of pharmacogenetic testing is not yet a routine part of scleredema care. If you are wondering about genetic testing for scleredema treatment, it is often more helpful to ask how your overall health, other medicines, and the type of scleredema you have may affect the safest treatment plan.
Interactions with other conditions
For many people, scleredema is not just about tighter, thicker skin on the neck, shoulders, or upper back; it can also make everyday movement harder, like turning your head while driving or lifting your arms to get dressed. Scleredema is often linked with other health problems, especially diabetes, and in some people it appears after an infection such as strep throat. Doctors call it a comorbidity when two conditions occur together. When scleredema happens with diabetes, high blood sugar may go along with more persistent skin thickening, and if the chest is involved, some may find deep breathing or exercise less comfortable. A smaller group of people with scleredema also have an abnormal blood protein disorder, including conditions such as monoclonal gammopathy or, more rarely, multiple myeloma, which is why doctors may suggest blood tests when the cause is not clear. Because the early symptoms of scleredema can overlap with changes caused by diabetes or other illnesses, it is important to look at the whole picture so treatment targets both the skin changes and any related condition.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Scleredema?
Other conditions that can look like scleredema include scleroderma, which also causes hard, tight skin and may affect other parts of the body, and morphea, which causes firm, thickened patches of skin. Doctors may also think about rarer problems such as scleromyxedema or eosinophilic fasciitis, because these can also make the skin and the tissues underneath feel thick, stiff, or swollen.
History
People living with scleredema often deal with skin that gradually becomes thick, firm, and hard to move, especially around the neck, shoulders, upper back, or face. Long before modern testing, doctors were already trying to sort out why some people developed this tight, heavy skin and why it sometimes followed an infection, appeared alongside diabetes, or showed up without a clear trigger.
First described in the medical literature as a distinct skin condition in the late 19th and early 20th centuries, scleredema was initially recognized by what doctors could see and feel during an exam. Early reports focused on the way the skin became woody or stiff without the pitting swelling seen in some other conditions. This mattered because scleredema could be confused with other illnesses that also cause skin thickening, and that confusion shaped how it was described for many years.
As medical science evolved, doctors began to notice that scleredema did not look exactly the same in everyone. Some people developed symptoms after a throat or other infection and improved over time, while others had a slower, longer course, particularly when diabetes was also present. That growing awareness helped separate scleredema into different clinical patterns and gave doctors a clearer sense of who might recover more quickly and who might need longer follow-up.
In recent decades, awareness has grown that scleredema is uncommon but likely underrecognized, especially when the early symptoms of scleredema are mistaken for simple swelling, weight changes, or another skin disorder. Researchers also came to understand more about the changes happening in the deeper layers of the skin, which helped explain why the skin feels thick and less flexible. Today, the history of scleredema is still being refined, but the main shift has been from a condition described only by appearance to one understood as a real, varied medical disorder that can affect daily comfort, movement, and quality of life.
