I got a book at the library written by an M.D. and it was about repetition stress injuries. The doctor was against playing with a flatpick. I can believe him, because holding a flatpick puts a lot of tension in the right hand.

If you have been using one, try doing without.

Another thing about corisone shots: my knee doctor told me that he has a patient who has come in for the shot every six months for ten years.
