Thanks for the advice, I'll discuss it with my Doctor. It's kind of weird in that when I'm playing the stiffness and locking up goes away after awhile It actually feels normal after execrcising it while playing. The locking up returns a few hours after playing and especially in the morning after a night of sleep. I thought maybe maybe the pinky was getting "musclebound" - but it sounds like it could be more serious. Glad you have been able to find ways to work around it. Gives me hope.
