Yes Bee. Once you have MS, everything is an MS thing.

I find it comforting to blame the Monster for every ache and pain.
However, since I'm not a Doc and don't pretend to be one on TV, May I suggest you see your Doc, to make certain.
I've never had tremours, except when putting my foot down on a nerve, sometimes tremours temporarily. I do have restless legs at night, though....can't keep them still.
