Kate, welcome to the best site for support. I too have the same symptoms as you, weaker on the left side, neck control problems, many signs of MS but don't have MS. I have had MG over 20 years and was treated by the guru of MG in NYC many years ago. So I know I have it. When I was DXed with MG it was believed that pain, one sided weakness, foggy brain, none of it was related to MG, but I see a lot has been learned over the last 20 years. A new Dr. is definitely needed for you. Good luck and keep us posted. Oh and Annie always give the greatest advice.
