In January 2007 I broke my wrist play basketball. In February of this year I started to play tennis, and made my high school team. Of course I wanted to be one of the best so I did some research online. I discovered the technique of pronation on the serve, or the snapping of the wrist. For the past 3 weeks or so my wrist has been extremely sore in non-tennis activity's, like lifting up my book bag, using my hand to get up or anything like that. But on the tennis court its not that bad once I hit for about 5 minutes. Is this most likely to my use of pronation or is it common to get sore like this during a tennis season?? P.S. I would describe the pain as about 7/10.
