It's an awful feeling, isn't it? I have the dizziness ocassionaly. It usually runs in cycles especially when I have been clenching bad. I was dx with benign positional vertigo and inner ear problems but the ENT told me they are directly related to my TMJ. Hopefully it will pass. My insurance doesn't cover anything TMJ related so I am stuck with this dreaded problem until I atleast win the lottery lol!
