My doctor thought I did for a while (and he still adds those tests to my visits), but it doesn't look so much like I have this dual diagnosis anymore. Just MS...
There is a least one other member of our forum who does have both diseases though. His screen name is Tomas2729. He might be willing to talk about it with you.
I don't have MG. I was tested for this before my MS diagnosis to rule MG out. I'm posting so that others get a chance to see your post...
Welcome to the forum, though! Have you started a DMD? I imagine that this new diagnosis has really taken you for a spin! What signaled that MS should be considered? What are some of your symptoms?
