I can't answer many of your questions because I was dx'd with general MG before any eye symptoms were evident to me. But I will say that your descriptions of the leg and arm weakness are EXACTLY what I experience. And the fact that it can be intermittent - - that's MG.

There are a few folks here who have both MG and thyroid dx's. I'm sure they will be able to help you more than I. Perhaps your father can check around to see if he can find a neuro who currently treats patients with MG. They are the ones who really get it.

Don't give up - - it can take an irritating long time to get a dx.
