Hi Kathie!

I'm not too sure as I don't know much about RSD. However, many people have more than one autoimmune disease. There are people on here that have MS along with diabetes, MG, Lupus, arthritis, thyroid disease, etc. So, based on this, I would think that if RSD is autoimmune related you can have both RSD and MG. Have you asked others on the MG forum if they have anyother autoimmune diseases, specifically neuromuscular autoimmune diseases? It would be interesting to see what they say.
