Hi The other day I was playing with one of my friends, and I was only receiving ball on the forehand, so after a few errors on the backhand when I finally got a chance, I decided (out of anger) to swing as hard as I could... however just after I had hit the ball a violent crunching noise came from the shoulder. Has anyone tried anything like that before? My shoulder still hurts, but normal forehand/backhands shots don't hurt at all, while serves only hurt a little bit. I think i'll take a rest with my shoulder untill this wednesday... Thanks!
