Perianal hematoma is a painful lump near the anus that happens when a small blood vessel bursts under the skin. It can affect adults of any age, and it often appears suddenly after straining, constipation, heavy lifting, or prolonged sitting. The early symptoms of perianal hematoma usually include sharp pain, tenderness, swelling, and a bluish or purple bump. It may help to know that doctors have studied this condition for decades, and most cases improve within days to a few weeks with rest, warm baths, pain relief, and avoiding strain. Perianal hematoma is usually not dangerous and does not affect life expectancy, but some people with severe pain may need a simple procedure to drain the clot.
How many people live with Perianal hematoma?
For perianal hematoma, exact worldwide and U.S. counts are not consistently reported by a single authoritative source. Because there is no named global registry or U.S. tracking system that gives a reliable count for this short-term condition, it is not possible to give a confident estimate of how many people are living with it worldwide or in the United States.
Overview
Perianal hematomaSymptoms
Perianal hematoma often causes a sudden, painful lump near the anus. Many people notice swelling, tenderness, and discomfort when sitting, walking, or having a bowel movement. The area can look blue or purple from trapped blood.
Outlook and prognosis
Perianal hematoma usually improves on its own within days to a few weeks, and many people feel much better as swelling and pain settle. Outlook is very good, though larger or very painful lumps sometimes need drainage.
Causes and risk factors
Perianal hematoma can happen after sudden pressure from straining during bowel movements, heavy lifting, hard coughing, or childbirth. Risk is higher with constipation, diarrhea, prolonged sitting, and pregnancy. Some people develop perianal hematoma without a clear trigger.
Genetic influences
Genetics are not thought to play a major role in perianal hematoma. It usually happens after pressure or straining causes a small blood vessel near the anus to break, though family tendencies like constipation may slightly affect risk.
Diagnosis
Perianal hematoma is usually diagnosed during a simple medical exam based on the look and feel of the swollen, painful lump near the anus. Tests are rarely needed unless symptoms suggest another cause, such as a thrombosed hemorrhoid or abscess.
Treatment and drugs
Perianal hematoma often improves with warm baths, rest, fluids, fiber, and pain relief such as acetaminophen or ibuprofen. If pain is severe or the lump is very large, a clinician may numb the area and drain the clot.
Symptoms
A perianal hematoma often shows up suddenly, with pain and a lump near the opening of the anus. Sitting down, walking, or having a bowel movement can make the area feel much more tender. The early symptoms of perianal hematoma are usually local rather than whole-body, so most people do not have fever or feel generally ill. Symptoms vary from person to person and can change over time.
Pain often starts suddenly and can feel sharp, throbbing, or like strong pressure near the anus. Some people notice it after straining, lifting, coughing, or a bowel movement.
Many people with perianal hematoma notice a firm lump just outside the anus. It may feel small at first or seem to appear over a few hours.
The area can look puffy and feel tight or stretched. This swelling often makes wiping, washing, or wearing snug clothing uncomfortable.
The skin over the lump may look blue, purple, or dark red because blood is trapped under the skin. The color can look dramatic, much like a deep bruise.
How people usually first notice Perianal hematoma?
People usually first notice a perianal hematoma when a painful, tender lump suddenly appears at the edge of the anus, often after straining with a bowel movement, heavy lifting, coughing, or sitting for a long time. The lump is usually blue or purple because it is a small collection of blood under the skin, and many people say the pain starts quickly over hours rather than gradually. When people ask about the first signs of a perianal hematoma, it is often this sudden swelling and sharp discomfort, sometimes with a feeling of pressure when sitting or wiping.
Types of Perianal hematoma
Perianal hematoma does not have formal medical subtypes, but the condition can show up in a few common patterns based on how much blood has collected under the skin and whether the area is starting to heal. Symptoms don’t always look the same for everyone. Early symptoms of perianal hematoma often include a sudden, painful lump near the anus, especially after straining, lifting, or constipation. For many living with perianal hematoma, the main differences are how painful it feels, how large the lump is, and whether it has started to drain.
Small hematoma
This form usually causes a small, firm lump at the edge of the anus with mild to moderate soreness. Some may find it is most noticeable when sitting, wiping, or having a bowel movement.
Large hematoma
A larger perianal hematoma often causes stronger pain, a tense swollen lump, and a feeling of pressure in the area. The skin may look dark red, purple, or blue, and daily activities like walking or sitting can become harder.
Ruptured hematoma
Sometimes the skin over the lump opens and a small amount of blood or clotted blood comes out. Pain may ease after this happens, but the area can remain tender and irritated while it heals.
Healing stage
As perianal hematoma improves, the lump usually shrinks and pain fades over days to weeks. Some people are left with a small loose skin tag after the swelling settles.
Can I slow down the onset of symptoms?
Only partly. There is no proven way to reliably delay or prevent a perianal hematoma, but research and everyday medical practice suggest that lowering pressure in the area may reduce the chance of one happening, especially by avoiding constipation and straining, keeping bowel movements soft with enough fluids and fiber, not sitting on the toilet for long periods, and being careful with heavy lifting. There are no standard screening tests or preventive medicines for this, but these steps may help lower risk even though they cannot guarantee it will not happen.
What genetics can tell you about symptoms
For perianal hematoma, genetics usually cannot tell you much about which symptoms you will have, how severe they will be, or when they will start. Symptoms such as a sudden painful lump near the anus, tenderness, and swelling are mainly linked to the size and location of the trapped blood and to triggers like straining, constipation, heavy lifting, or pregnancy, rather than to a known gene change. In a small number of people, inherited tendencies that affect blood vessels, bleeding, or clotting may influence how easily these lumps form or how much bruising occurs, but this is not a well-established genetic pattern for the condition itself.
Causes and risk factors
Perianal hematoma often starts when a small vein just outside the anus breaks after a sudden rise in pressure. This can happen with straining during a bowel movement, constipation, heavy lifting, a hard cough, or childbirth. Risk factors for perianal hematoma include long periods of sitting, a low-fiber diet, not drinking enough fluids, and pregnancy. Some risks are modifiable (things you can change), others are non-modifiable (things you can’t). There is no single gene behind perianal hematoma, but family tendencies toward constipation or weaker vein walls may slightly raise the chance for some people.
What are the most common causes or risk factors?
A perianal hematoma usually happens when a small blood vessel just outside the anus breaks and blood collects under the skin. It is most often linked to anything that suddenly raises pressure in that area, such as straining with constipation, passing a hard stool, heavy lifting, a hard cough, or sitting for a long time, including spending a long time on the toilet. Pregnancy and childbirth can also raise the risk, and there is no clear inherited or genetic cause known for most people.
Environmental and biological risk factors
A perianal hematoma happens when a small vein just under the skin near the anus suddenly breaks and blood collects there. Common risk factors for perianal hematoma are things that sharply raise pressure in these veins or make the vein wall easier to injure. Doctors often group risks into internal (biological) and external (environmental).
Hard stools and pushing during a bowel movement can sharply raise pressure in the small veins around the anus. That sudden pressure can cause a vein to break and form a perianal hematoma.
Frequent loose stools can irritate the area and lead to repeated urgency or straining. This can make delicate surface veins more likely to bleed under the skin.
Pregnancy increases pressure in the pelvic and anal veins as the uterus grows and blood flow changes. Labor and pushing can add a sudden strain that may trigger a perianal hematoma.
Ongoing coughing, repeated sneezing fits, or frequent vomiting can cause repeated spikes in pressure inside the abdomen. That pressure can be transmitted to the veins near the anus.
Genetic risk factors
Perianal hematoma is usually not a genetic condition, and no specific gene has been shown to cause it. Some risk factors are inherited through our genes, but perianal hematoma does not usually follow that pattern. In most cases, there are no clear genetic risk factors for perianal hematoma, and it does not strongly run in families. Rare inherited disorders that affect blood vessels, supportive tissues, or bleeding can sometimes be relevant, but they are not a typical cause.
No known gene: No single inherited gene is known to directly cause perianal hematoma. Most people who develop one do not have a clear genetic reason behind it.
Family history: Perianal hematoma does not usually run strongly in families. If several relatives have easy bruising, unusual bleeding, or vein problems, a doctor may consider a broader inherited condition instead.
Connective tissue disorders: Rare inherited disorders that weaken the body's supportive tissues can make veins and nearby tissue more fragile. This may increase the chance of bruising or vein-related problems, but it is not a common proven cause of perianal hematoma.
Bleeding or clotting: Rare inherited bleeding or clotting disorders can affect how blood collects or forms clots. These conditions are not a usual cause of perianal hematoma, but they may be considered when episodes are repeated or happen with other unusual bleeding or clotting symptoms.
Lifestyle risk factors
Daily habits that raise pressure in the anal area can make a perianal hematoma more likely. The main lifestyle risk factors for perianal hematoma involve straining, bowel habits, prolonged sitting, and activities that sharply increase abdominal pressure. Diet, hydration, physical activity, and alcohol use can all influence these triggers.
Repeated straining during bowel movements increases pressure in the small veins around the anus. This can cause a vein to rupture and form a painful perianal hematoma.
A diet low in fiber often leads to hard stools and difficult bowel movements. That makes straining more likely and raises the chance of developing a perianal hematoma.
Not drinking enough fluid can make stools drier and harder to pass. This can increase pushing and worsen the lifestyle risk factors for perianal hematoma.
Lifting heavy weights or doing intense exertion with breath-holding can sharply raise pressure in the pelvic and anal veins. That sudden pressure may trigger a perianal hematoma in some people.
Risk prevention
Perianal hematoma can happen suddenly, often after straining during a bowel movement, heavy lifting, or anything that sharply raises pressure around the anus. It is not always fully preventable, but many people can lower the chance of it happening by keeping stools soft and avoiding repeated strain. Prevention is about lowering risk, not eliminating it completely. For many, this also means reducing the same triggers that can worsen pain or swelling if early symptoms of perianal hematoma start to appear.
Hard stools and pushing are major triggers for perianal hematoma. Drinking enough fluids, eating fiber-rich foods, and staying active can help bowel movements pass more easily.
Sitting and pushing for a long time on the toilet raises pressure in the veins around the anus. Going when you feel the urge, taking your time without forcing, and not lingering on the toilet may reduce risk.
Heavy lifting can suddenly increase pressure in the lower pelvis and around the anus. Using proper lifting technique and avoiding breath-holding during exertion may help prevent perianal hematoma.
Ongoing diarrhea or repeated constipation can irritate the area and increase pressure with frequent wiping or straining. Managing these problems early with diet changes or medical advice can lower the chance of another episode.
Can you prevent Perianal hematoma?
You usually cannot fully prevent a perianal hematoma, but you may be able to lower the chance by reducing strain and pressure around the anus. The most helpful steps are avoiding constipation, not pushing hard during bowel movements, staying well hydrated, eating enough fiber to keep stools soft, and being careful with heavy lifting when possible. Even with these steps, some people still get one.
Transmission
A perianal hematoma can show up suddenly as a painful lump near the anus, but it is not an infection and it cannot be passed from one person to another. Many people ask, is perianal hematoma contagious, and the answer is no.
Perianal hematoma usually happens when a small blood vessel under the skin around the anus breaks and bleeds, often after straining with a bowel movement, heavy lifting, coughing, or childbirth. It does not spread through close contact, sex, shared bathrooms, food, or blood exposure, so it is not considered infectious at all.
When to test your genes
For a perianal hematoma, genetic testing is not part of early detection or routine care. This is usually a local blood vessel problem caused by pressure or straining, not an inherited condition. If these lesions keep coming back or you also have unusual bruising or bleeding, your clinician may consider blood-clotting tests instead.
Diagnosis
A perianal hematoma is usually diagnosed from what the area looks and feels like, along with your symptoms. It often appears suddenly as a painful lump near the anus, sometimes after straining, heavy lifting, or constipation. Doctors usually begin with a gentle exam, and in most cases the diagnosis of perianal hematoma does not require complex testing.
Your doctor will ask when the lump appeared, how quickly the pain started, and whether you have had constipation, straining, heavy lifting, or recent diarrhea. A detailed family and health history can help, but the focus is usually on recent symptoms and triggers.
The diagnosis is often made by looking at the area and gently feeling the lump. A perianal hematoma typically appears as a tender blue-purple swelling at the edge of the anus, which helps distinguish it from other causes of anal pain.
Doctors also look at the timing and type of symptoms. Sudden pain with a new outer lump fits a perianal hematoma more than conditions that cause bleeding, fever, or symptoms that build more gradually.
Your provider may suggest a closer exam if the diagnosis is not clear or if the pain seems out of proportion to the visible lump. This helps rule out problems such as an abscess, thrombosed hemorrhoid, anal fissure, or other causes of a painful anal lump.
How is Perianal hematoma diagnosed?
Perianal hematoma is usually diagnosed with a simple exam and a talk about your symptoms. A doctor will ask when the painful lump appeared, whether it started after straining, heavy lifting, coughing, or constipation, and will gently look at the area to see if it has the typical dark, tender swelling caused by trapped blood under the skin. Most people do not need scans or lab tests, but more tests may be done if the lump does not look typical or if there are warning signs like fever, pus, heavy bleeding, or ongoing changes in bowel habits.
Stages of Perianal hematoma
Perianal hematoma does not have defined progression stages. That is because it usually appears suddenly as a small pool of blood under the skin near the anus, rather than moving through predictable phases over time. Doctors usually start with a conversation about when the lump, pain, or swelling began, since the early symptoms of perianal hematoma often come on within hours after straining, heavy lifting, coughing, or a bowel movement. Diagnosis is usually based on the symptoms and a physical exam, and follow-up focuses on whether the pain is easing and the swelling is shrinking over days to weeks.
Outlook and prognosis
The outlook for a perianal hematoma is generally excellent, with most cases improving on their own over several days to a few weeks. Pain and swelling are often most intense in the first 48 to 72 hours and then gradually settle as the trapped blood is reabsorbed. If the clot is large or very painful, drainage can bring faster relief, and recurrence is possible but not common. Long-term complications are uncommon, although temporary discomfort, skin irritation, or a residual skin tag can occur. A perianal hematoma is not usually dangerous and does not increase mortality, but ongoing bleeding, fever, worsening pain, or signs of infection should prompt medical review because they may suggest another condition or a complication.
Long-term effects
Most people with a perianal hematoma recover fully over days to a few weeks, and lasting problems are uncommon. The main long-term issue, if one happens, is usually a small leftover skin tag or occasional discomfort rather than ongoing disease. It’s important to remember that long-term doesn’t always mean progressive. Thinking about the long-term effects helps set expectations after the swelling and pain start to settle.
Mild tenderness or a sense of pressure can last for a short time after the lump shrinks. This is usually most noticeable when sitting for long periods or during a bowel movement, but it often continues to improve.
After the trapped blood is reabsorbed, some people are left with a small flap of skin at the anal edge. This is harmless, though it can make cleaning harder or feel irritating at times.
A perianal hematoma can come back, especially if straining, constipation, heavy lifting, or long periods of sitting continue to put pressure on the area. In that sense, what seem like early symptoms of perianal hematoma may return during another episode rather than become a permanent problem.
For many, pain during the first episode can lead to fear of passing stool for a while. That may contribute to constipation and more straining, which can briefly slow recovery or raise the chance of another hematoma.
How is it to live with Perianal hematoma?
Living with a perianal hematoma can feel suddenly disruptive because the pain often comes on fast and can make sitting, walking, bowel movements, and even sleep uncomfortable for a few days. Many people find that work, driving, exercise, and intimacy become harder until the swelling settles, but the condition is usually short-lived and does not mean something dangerous is happening. People around you may notice that you need to rest more, move carefully, or avoid long periods of sitting, yet with simple care and time, most people recover well and get back to normal routines.
Treatment and drugs
Perianal hematoma is often treated by easing pain and letting the trapped blood reabsorb on its own, which can help if sitting, walking, or having a bowel movement has become uncomfortable. Small perianal hematomas often improve over several days to a few weeks with home care such as warm sitz baths, gentle cleaning, avoiding straining, drinking enough fluids, and using stool softeners or fiber if constipation is a problem. Medicines that ease symptoms are called pain relievers, and doctors may suggest options such as acetaminophen or, for some people, an anti-inflammatory medicine if it is safe for them. If a perianal hematoma is very painful, large, or caught early, a doctor may numb the area and make a small cut to drain the clot, which can bring faster relief. If pain is worsening, the area keeps enlarging, or there is bleeding, fever, or trouble passing stool, prompt medical care is important because not every painful lump near the anus is a perianal hematoma.
Can you cure Perianal hematoma?
A perianal hematoma, which is a painful lump caused by trapped blood under the skin near the anus, usually gets better and goes away on its own, so most people do not need a special cure. Treatment is mainly about easing pain and helping the area heal, such as warm baths, pain relief, rest, and keeping bowel movements soft. If the lump is very painful or large, a doctor may drain it to give faster relief.
Non-drug treatment
A perianal hematoma can make everyday things like sitting, walking, or having a bowel movement feel surprisingly uncomfortable. Many living with perianal hematoma improve with simple care at home, especially when the swelling is small and symptoms are easing. Managing this condition often starts with reducing pressure on the area, keeping stools soft, and giving the body time to reabsorb the trapped blood. If pain is severe, the lump is growing, or symptoms are not settling, a clinician may suggest a minor procedure instead of home care alone.
Sitting in a warm bath or sitz bath for 10 to 15 minutes a few times a day can relax the area and ease soreness. This can be especially helpful after a bowel movement, when the skin may feel tight or irritated.
A wrapped cold pack during the first 24 to 48 hours can help limit swelling and numb the area. Keep it on for short periods, such as 10 to 15 minutes at a time, to protect the skin.
Drinking enough water and eating more fiber can make stools easier to pass and reduce straining. For many, treatment begins not at the pharmacy, but with small daily steps like fruit, vegetables, beans, and whole grains.
Try not to sit on the toilet for long periods or push hard during a bowel movement. If you are searching for how to treat a perianal hematoma at home, gentler toilet habits are one of the most important early steps.
Your genes may have an impact on how drugs work for you
For people with a perianal hematoma, treatment usually focuses on pain relief, easing bowel movements, and sometimes a simple procedure to drain the trapped blood, and genes do not usually play a big, proven role in how these treatments work. That said, people can naturally differ in how well common pain medicines help them or how likely they are to get side effects like nausea, sleepiness, or stomach upset. In everyday care, things like age, other health problems, and especially medicines that thin the blood often matter more than genetics because they can affect bleeding and healing.
Pharmacological treatments
Pain from a perianal hematoma can make sitting, walking, or having a bowel movement feel much harder for a few days. Medication can feel like a big step, but for perianal hematoma, drug treatment is usually short-term and aimed at easing pain and making bowel movements less painful. Many people living with perianal hematoma do not need prescription medicine, and the clot itself often settles with time. If symptoms are severe or the lump is very new and tense, a clinician may drain it, using numbing medicine during the procedure.
Acetaminophen is often the main pain medicine used for perianal hematoma because it can ease soreness without affecting bleeding. It may be a good first option for people who cannot take anti-inflammatory drugs.
Ibuprofen or naproxen may help with pain and swelling in some people with perianal hematoma. These are not right for everyone, especially if you have stomach ulcers, kidney disease, are on blood thinners, or your clinician is concerned about bleeding.
Lidocaine cream, gel, or ointment can briefly numb the area and may make sitting or bowel movements more tolerable. It treats discomfort, not the blood clot itself, so it is usually used for short-term relief.
Docusate or polyethylene glycol may be used if passing stool is painful or straining is making symptoms worse. This can be especially helpful when early symptoms of perianal hematoma include sharp pain during bowel movements.
Genetic influences
Perianal hematoma usually happens after sudden pressure on the veins around the anus, such as during straining or heavy lifting, so genes are not thought to be the main cause. Genetics is only one piece of the puzzle, but some inherited traits may make constipation, vein fragility, or easy bruising more likely. That means family tendencies toward hemorrhoids or long-term constipation can be part of the risk factors for perianal hematoma, even though the actual swelling is usually triggered by pressure or strain. There is no well-established single gene test for perianal hematoma, and it is not usually considered an inherited disorder. If these swellings happen often, or if you also bruise or bleed easily, doctors may look for other conditions that can run in families, including bleeding problems. For most people, though, everyday factors like constipation, diarrhea, coughing, childbirth, or lifting something heavy matter more than genetics.
Is Perianal hematoma genetic?
Genetics are not thought to play a major role in perianal hematoma. It usually happens after pressure or straining causes a small blood vessel near the anus to break, though family tendencies like constipation may slightly affect risk.
Having a genetic risk is not necessarily a diagnosis
Gene variants are a normal feature of human biology and are common across the general population. Most do not directly affect health and simply reflect natural human diversity. For many genes, carrying a variant tied to a condition points to a possible association, not a definite diagnosis, especially when several genes and environmental factors are involved. In some situations, though, one well-characterized variant in a particular gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many people, the hardest part of a perianal hematoma is sudden pain when sitting, walking, or using the bathroom, so treatment is usually focused on easing pain and avoiding constipation while the area heals. Genetics usually do not change the main decision about treating a perianal hematoma, because doctors rely more on the size of the lump, how severe the pain is, and how recently it started, since a small procedure may help early on. Where genes can matter is in how your body handles some pain medicines, so codeine or tramadol may work poorly for some people and cause more side effects in others.
Genetics is only one factor, and age, other medicines, liver and kidney health, and whether you can safely take anti-inflammatory drugs often matter more when choosing which pain medicine works best for a perianal hematoma. Because of that, pharmacogenetic testing is not a routine part of perianal hematoma care, but it may occasionally help if someone has had unusual reactions to pain medicines or if stronger prescription treatment is being considered.
Interactions with other conditions
Perianal hematoma can be more bothersome when it happens alongside constipation, diarrhea, or hemorrhoids, because all of these can increase pressure, straining, or irritation around the anus. Someone might notice their symptoms flare when another condition is active, such as after a stomach bug causes frequent bowel movements or when chronic constipation leads to repeated straining on the toilet. People with inflammatory bowel disease, anal fissures, or frequent coughing from lung disease may also be more likely to develop or worsen a perianal hematoma because the veins in the area are under extra stress. Blood-thinning medicines and bleeding disorders do not usually cause a perianal hematoma by themselves, but they can make swelling and bruising larger or last longer. In day-to-day life, this can mean the pain from sitting, walking, or having a bowel movement feels harder to sort out, especially when early symptoms of perianal hematoma overlap with another anal or bowel problem. If the lump is very painful, keeps growing, or comes with fever, drainage, or ongoing bleeding, it is important to get checked, since those signs can point to a different condition such as an abscess or another cause of anal pain.
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 Perianal hematoma?
A perianal hematoma is most often mistaken for a hemorrhoid, especially a painful outer hemorrhoid, because both can cause a sudden, tender lump near the anus. Other problems that can feel similar include an anal fissure, which is a small tear that causes sharp pain and bleeding, and a perianal abscess, which is an infected swollen area that may also cause warmth, redness, or fever. Less often, a skin tag or tissue from an internal hemorrhoid slipping outward can also look similar.
History
A tender lump near the anus can appear very suddenly, sometimes after straining on the toilet, lifting something heavy, or a hard workout. Many living with perianal hematoma describe it as a sharp, bruised swelling that makes sitting, walking, or having a bowel movement uncomfortable. Across cultures and time periods, painful anal lumps were often grouped together, so perianal hematoma was not always clearly separated from hemorrhoids in older medical writing.
For a long time, doctors mainly described what they could see and feel during an exam: a tense, blue-purple swelling at the edge of the anus that came on quickly. Early reports often mixed these episodes with what people called “external hemorrhoids,” because both can cause pain and swelling in the same area. As medical science evolved, clinicians came to better understand that a perianal hematoma is usually a small collection of blood under the skin rather than the same process that causes typical hemorrhoids.
That clearer distinction mattered because it helped explain why symptoms often begin so suddenly and why the lump may slowly shrink as the trapped blood is reabsorbed. In recent decades, awareness has grown that people with perianal hematoma may do well with simple care when symptoms are improving, while others with severe pain may benefit from a small office procedure to release the clot. Knowing this history also helps make sense of why many people still hear different names for the same problem, and why early symptoms of perianal hematoma are sometimes mistaken for hemorrhoids even today.
