pain in both shoulders

[Slicer]

I am a college player and play 5 times a week first we condition then run through drills and then some play usually 3-4 hrs a day plus game days on top of this. I've noticed that both my acromioclavicular joints are both pretty painful. I'm not feeling any pain from the infraspinatus or the supraspinatus. Though if I abduct my left arm straight up it pops and I'm right handed but what really hurts is when I raise both arm with a 90 degree bend at the elbows and the arms are parallel with the floor I try to retract and man that's painful. Guess it's off to see that trainer.. crap.. anyone else experience this condition...
Thanks...Slicer

Slicer,

I use to get the condition you describe all the time and the only
way I was able to cure it is take 2 months off and go through
extensive therapy. Swimming really helps a great deal, along with
pilates and yoga. Good luck!
