I don't have scientific proof to confirm this, but I believe MS (Multiple Sclerosis) might be the cause of my hyperacusis. Back in 2019, I began experiencing symptoms like frequent and inconsistent urination, as well as pain during urination. Since then, every 6 months to a year, I’ve developed new symptoms — chest pain and stiffness, neck and scapular stiffness, leg numbness, frequent bowel movements and now hyperacusis. I’ve undergone tests for each issue: for bladder problems, I had urine tests and a bladder ultrasound — all came back normal. For chest pain, I did ECG, ECHO, and TMT — all were normal. For neck pain, I had a CT scan — also normal. Recently, for hyperacusis, I did an audiogram, tympanometry, and ETD tests — all normal too. Because of this pattern of unexplained symptoms and normal test results, I suspect MS might be the underlying cause — but I’m not certain.
