Look, you need to get other opinions. Just because two docs are not giving you any answers doesn't mean there are none. I had to take control of my own medical care years ago when two orthopedic surgeons told me point blank after a cursory scan of my records that there was nothing to be done, just live with it. I finally found a neurologist in private practice who spent over an hour and a half checking me over (yes, an hour and a half). She put me on a cocktail of meds that, at first, made me dizzy and unsteady. After a few days things settled down. In a few weeks I was able to get out and start cycling again. Had I listened to those first two guys, I would likely be in a nursing home by now. Good luck!
