To echo Gary - bummer! Scott, I have no medical expertise and all I can do is wish you well and to have a speedy recovery from whatever treatment is necesaary.

I must've lucked out in this regard. I've never had any training and my hands just play the way they play. I'm certain a teacher would howl in horror at the way I find my way around a keyboard, but I've never had so much as a twinge. Go figure, eh?
