RE: Guy's, if you were wondering...
Rotator cuff injuries are the worst.
I stuggled throughout high school baseball with that injury. I used to pitch and play third base and every time I threw the ball it just hurt like hell. By the end I had to switch to 1st base because my arm was shot.
Finally, I got hooked up with a good athletic trainer who showed me some strengthening excercises. That's the best thing you can do. Good luck and I hope you heal soon.
