Hi, Trobentica. Welcome. I would love to know how you came up with that name, it's very unusual!

I have looked and looked and the only studies I have found are in relation to what a lack of acetylcholine does to the muscles and what overuse in "normal" people does to the muscles. There are no specific MG studies that I have found, which doesn't really surprise me. Maybe there are some but I cannot find any no matter how I search. Doctors have not seemingly been concerned - or apparently interested - at all in the secondary effects of pain in MG but only in the primary weakness.

It is a pretty basic physiology situation though. When muscles get worn out and weak, they can cramp or spasm. Like marathon runners or long-distance bikers or any other athlete who does something for a long or sustained time. It just takes a far shorter time to happen to the muscles of someone with MG.

I'm sorry I can't help. Have you had MG long? Are you doing okay?
