It started this morning when I leaned over to pick a book up off the floor. Now I can barely move.

A muscle between my shoulder blades cramped and it hasn't stopped. Went to the doctor this evening, and she said it was a muscle spasm. Unfortunately, the painkiller and muscle relaxer and heat
aren't helping much. It's hard to move or breathe and I'm bored out of my mind. Anyone ever dealt with this? Any suggestions??
