Am I responsible for this quandry? I questioned whether you had fatigable weakness that was demonstrated by a clinical exam - which obviously you have had. And your SFEMG demonstrates that as well.

What I was trying to point out in my other post was that MG has weakness that clearly fatigues upon exertion or repetitive activity. Like Alice said, paraphrasingly, "Do this, that happens."

I asked the question because you can have muscle weakness from a fluctuating thyroid condition or electrolytes being off but it won't specifically be related to an activity. I certainly didn't ask in order to make you doubt the basics.

It's possible for you to have BOTH.

With MG, however, you have to see it in "action" in order to know how it is behaving. Like Alice said too, just sitting in an exam room might not show a doctor how weak you are. Except for that time you pushed for a longer period of time and got weaker. The best neuros put a suspected MG patient through a veritable workout.

I'm sorry if I added to your questions instead of helping.
