Do any of you have muscles that jump. Mine will jump sporatically over my whole body. They don't last but a few seconds, but you can see them jumping under my clothes. They are painless but just a little bothersome. When I was on Mestinon 60 mg twice a day, they were a lot worse. My eye would jump like crazy. My muscles were jumping even before I was diagnosed. I have not read where this is happening to anyone else. I just wondered if it is coming from MG or something else. busybusy
