I wish there was a definite answer on pain. It seems that most say that pain is not part of this thing but then there are others who say they have pain. This seems to be a major symptom for my hubby these days. Still no answers though. He still has the twitching and some weakness. I wonder sometimes if the pain could be an indirect symptom. As in, if you are weaker but still using the muscles it would create pain?! -me-
