Suggest Treatment For Superior Semicircular Canal Dehiscence

I ve had most of the symptoms of SSCD (Semicircular Canal Dihisence) for the past year or more. Autophony and vertigo being the main ones. I get vertigo when I strain the slightest bit, cough or sneeze. Also when I hum at a certain pitch and volume everything goes on tilt. Very scary, especially while driving. I used to enjoy singing along with my CD while driving but it s now too dangerous! The autophony is also quite annoying, as when I speak I can t hear anything else, as my own voice is amplified extremely loud in my head. My question is, could there be another cause for these symptoms other than SSCD? Could a simple buildup of ear wax cause this? I can hear fine normally. So I didn t think ear wax buildup was the cause, but I may be wrong....
