Do you have limited range-of-motion in that shoulder?
Actually, no. Thats a big reason why I never sought out any medical care. It hurt like a bitch for about 8 weeks, but my range of motion came back just fine and it didn't prevent me from doing any other weightlifting or training in general. I didn't realize it was affecting squats because honestly I got lazy and just neglected my lower body for far too long.
It bugs the crap out of me not being able to do the lifts that I want, so I think I will find some general rotator cuff rehab exercises to work on in addition the the other aides mentioned.
