I have unilateral tinnitus from about 4 months, feel a little unsteady sometimes. no hearing loss. worried abt acoustic neuroma , is it common?

See ENT doc.: Not likely, but could be acoustic neuroma. See ENT doc for evaluation.

No, but.....: Acoustic neuroma isn't common but it happens and it is serious. Your symptoms are worrisome. In any case you need to see a doctor about your symptoms. You can start with a primary care physician who will refer you to the appropriate specialist for further evaluation. Please don't procrastinate!
