maybe - I've only ever had problems with my picking arm, so can't really relate directly. I used to lock my arm when alternate picking, and as a result got pain in the back of my right elbow bad enough that it hurt to touch, and I could hardly play...

You're going to have to go very slow and figure out where the problem is - you might not need to see the Doc just yet... very simple one - are your fingers white near the tips when you play?
