I have to confess that I've had this hip problem before. It got better during winter (no tennis), but now it's getting progressively worse as I play tennis more often. It's on my hitting arm side (lefty). I almost don't can't sleep on its side because it hurts, it reduces my mobility as well. I hate taking aspirin, I tried RICE before...but not being able to play sucks. My goal now is not just to alleviate the pain but to prevent it from happening again, is there an exercise/stretch I can do before playing? Thx much!
