Before you do anything, apply for the VA disability, or for a FAA medical, you really should consult a medical service that specializes in the curve balls of the FAA medical world, and let them guide you. AMAS (aviation medical advisory service) comes highly recommended.

If you happen to be an AOPA member, they have a subscriber service that provides assistance with legal questions and medical issues, though for a question such as yours, I'd go with AMAS first.
