Have you been back to the doctor since you posted this? I would think that your primary would send you to both a neurologist and a rheumatalogist. Write down all your symptoms, when they started, how bad they are (scale of 1 to 10), what tests you have had so far but insist they re-do them. I hope you get some help. You have to be pro-active. I know I have had to be. I have CFS, Fibro and Peripheral Neuropathy and had a positive ANA test but no answer why. It's difficult but please try to get answers.
