Recently (2 weeks) I changed to a Western forehand grip from an Eastern one. It has allowed me to more naturally use hip and shoulder rotation, thus I have improved my forehand and I am able to generate decent amount of topspin and power. btw, I am a leftie and 3.0 or less player. I also changed racquet around the same time I changed my grip from a basic 10 oz one to Babolat AeroPro Drive Cortex, 11.6 oz. Thus, in the last 2 weeks I have made my grip quite extreme and increased racquet weight. 2 days ago, while trying to hit a forehand on a short slow ball, I was not in a position to use much body rotation. Ended up using hand power and twisted my wrist in a weird fashion. Since then, I have pain and am unable to play forehand at all. Specifically, the pain happens when I try to supinate my arm, eg. if my forearm is resting on thinghs with palm facing up, if I put a 5 lb weight in the palm and supinate, I can sense pain in ulnar region, perhaps flexors and extensors. In the regular game, during the forehand contact, the hand naturally supinates a bit due to collision with the ball which causes pain. I have been icing ever since the pain started. I don't notice any inflammation. Has any one gone though a similar problem? Can someone suggest remedies? I do plan to see a physical therapist next week. I want to start playing tennis again soon enough.. Thanks!
