For twenty years since I left a went scuba diving in connection with a cruise vacation, I have had daily problems with balance. Dr. Timothy Hain, Northwestern University, Chicago, seemed to believe I had a damaged vestibular system. One other doctor initially thought that I suffered with mal de dubarquement. Dr. Hain seemed to rule out this condition. What should I do in the way of trying to determine if anything can be done to alleviate my balance problems?
Hello! I read your question and understand your concern.  I agree with your doctors that your balance problems may be related to the inner ear. But they also may be caused by the brain problems or vertebral artery narrowing. The long time you refer with these problems, is more indicating an inner ear problem.  Vestibular tests can diagnose disorders such as benign paroxysmal positional vertigo, and perilymph fistula, whicChatDoctormonly occur after head injury; and bilateral vestibular cytotoxicity, whicChatDoctormonly is a side effect of medication. I would recommend tests like electronystagmography, electrocochleography, rotational chair test, posturography, fistula test to find out a possible inner ear problem. A brain MRI may be needed if everything results normal. Hearing pathway tests (audiometry, auditory brain stem response, electrocardiography) can also be used for the same purpose, and are frequently combined with vestibular tests. After finding the cause of your problems than we can choose the right treatment. Hope to have been of help! Best wishes!
