I've been playing tennis quite regularly now at least once if not twice a week, usually in 2-3 hr periods but each time I play I get terrible pains in my wrist/carpal bone area. I'm pretty sure its because I put a lot of pace into my serves and sometimes I'll lose a little grip so I'm thinking about changing it (rackets only a couple of months old, Wilson H6). Just wondering if there was anything I could do to try and prevent these pains. Perhaps some write/hand exercises etc? Supports?
