neuro-opthamologist is a great start!!! He gave me my first DX. My blood work for the Neuro had come back Neg but the neuro-opthamologist said he didn't care about the blood work MG was the only answer for my double vision and within a year my blood work would come back positive or "he would eat his hat" well he was 100% correct.

I do get cramps in my feet and hands but think it one of the multitude of meds I take but not sure.
Good Luck
Mike
