Shoulder Pain

I've mentioned previously that my shoulder has been hurting when I start playing.  Today, it started and never quit.  I had a feeling it was due to the rotator cup and/or the amount of weight i put on it during and after a shot.  Well, I did some searching around it seems I was right - or pretty close to it.  Now, I'm not foolish enough to grab a diagnosis from some internet forum; but I do think the symptoms are so similar that the suggestions given, which have worked for the original poster, are definitely worth a try.
