Sports Injury

I will know tomorrow if there is really something wrong with my thumb. I hurt my thumb back in March playing tennis. I'm not a tennis player but I know that it's a bad idea to hit myself with a tennis racket. But for some reason when I swung the racket, my other hand decided to move towards the oncoming racket and smack right into it. It's been hurting since March, but now that work isn't too busy, I think it's a good time to get it checked out now. Hopefully nothing is really wrong with it and that a brace will suffice.
