Ok, so I guess the answer is still probable MS ?? I still need to get a proper MRI, one with contrast.

I have had all the "other" test to rule out "other" things.......

I don't know of any other disease or syndrom that cause a person to to have frequent set backs "crashes" and that take sometimes weeks to recover from, also they always leave residule effects. ie more weaker, more fatique, more everything.

For example if it was just say vit B12 I would just have the neuro effects but not the crashing. Is that right ????

I do suspect that I have some form of MG, I take Mestinon when I really have to, and it works great, just hate the side effects. It doesn't stop the crashes though. The neuro that perscribed it says that I don't have MG......

Any ideas would be most greatful, thanks, Patricia
