What is Imuran? I have never taken it. I know that some medications can cause flu like symptoms like body aches. Could that maybe be a part of it? Or maybe your potassium is low. My legs will cramp every once in a while but i just keep trying to drink lots of fluids and eating bananas. I am also I guess in remission. No doctor has really said "yes, your in remission." I am only taking half a mestinon every once in a while. lets say average every other day. I am way better then when I started. lol If you figure anything out about the muscle pains keep me updated. I would love to know.

Sugarkiss-Also I didnt know you could really take vicodin on a daily basis. I thought it would be considered a warning drug. Do you think it could be worsening your MG?
