TwitchyMD,First, consider yourself lucky that it has taken 4 years for the aches and pains to kick in, for me, it happened in the very beginning. That said, I have to say that I worry about you focusing on your sxs so much. I can totally relate to how you feel and the overwhelming desire to know what is causing your sxs, but in the end, there are no good answers, only misery awaits you.....believe me, I've been there! Now, I'm not saying you should stop looking for answers, but I hear you talk about "repeatable" this and "induced" that and I flash back to myself and that all emcompassing fixation I had on my condition. It isn't good for you or your loved ones. At some point, you have to accept this mysteries diagnosis of "benign" whatever your neuro calls it and get on with your life. Do yourself a favor and work on your anxiety, stop focusing on your sxs, and go play golf or watch a movie or kiss your wife......life is just too short to be inducing cramps in perfectly normal muscles.Take care,Gary
