Find an MS center. Seek their help, and direction. they are very good at ruling out ALL other things before they slap you with an MS label.
PLEASE dont give up! Most of us have walked a fair mile or two in those shoes. NO ONE wants to be sick! NO ONE! What we want is answers to WHAT HAPPENED TO ME!?!
I have that flash bulb thing in my eyes. I suffered from Optic nueritis and that is one of the halmarks. Please, send this neuro packing, and seek higher ground. NO ONE in the medical field has the right to treat you that way. Even if you were faking or looking for attention, they have NO right to treat you that way.
Come back and tell us what you chose to do.
hang in there.
