I've already torn my rotator cuff once in May, didn't need surgery, just did some physical therapy to rehab it. Now I re-injured my shoulder around thanksgiving, and it has improved, but I can't but my hand all the way behind my back, and have some tightness when trying to raise my arm above my head. Also the front part of my shoulder is very tender. I've been told its just tendinitis, but I'm not sure


just looking for advice
