Does anyone else have this thing where certain muscles like on your forearm or maybe somwhere in a foot or your face even, where the muscle just starts to tighten?? I dont get any pain with it at all when it happens, but its just random muscles every so often. Is this a cramp without pain or is it just another form of a twitch?? Like I said, no pain, just strange tightning at random. It only last for a few seconds and can be rubbed away and then its gone. I get them in my face and feet sometimes. And in my arm occasionally. Anyone know what it is or is it more reason for concern in the ALS department?? Hope someone would know something about this. Thanks so much.P.S. oh ya, I get them rather frequently in my left wrist and in my right hand also. Just wanted to add that.
