I feel for you. I expect to be in the same situation myself after one more visit to the Neuro.

But I can't accept the "it could be worse" lecture. After all if the tests for MG are negative and those for MS, ALS etc etc. It doesn't mean that you haven't got one of these terrible conditions, it simply means that the tests haven't found it yet.

Where is the real world "Dr House" who will move heaven and earth to solve a riddle and find a solution?
