People with active cochlear Ménière’s disease usually first notice hearing changes in one ear that seem to come and go—things sound muffled, distorted, or unusually loud, and low tones may feel “boomy” or hard to catch. Many also describe a sense of ear fullness or pressure and bothersome ringing (tinnitus), without the spinning vertigo that classic Ménière’s disease often brings. These “first signs of active cochlear Ménière’s disease” often prompt an ear exam and hearing test when symptoms recur over days to weeks.
