Sorry to hear what happened. I hope it's nothing serious, but if it sticks around you may want to see a doc. I would say when you start playing again that you go slowly with some easy warm-up exercises for longer than you normally do. If you feel pain then stop for a while and try again. More pain, then maybe stop for the day.

If you can't play for a while then look into doing "mental practice":
