Your ENT did an EEG ... what about allergy testing or vertigo/balance testing for Meniere's ??? Brain scan seems rather severe if you ask me. How long have you been off the Cymbalta? Sometimes a reaction to a med takes me a month or more to rid.

Ok, how is your jaw? Do you grind your teeth at night, or find your jaw sore at all? TMD can cause vertigo. How long since you've seen a good dentist/oral surgeon? Sigh PC is wracking their collective brain to try and figure this out for you

grrrrrr ...
