I was in a collision on the basketball court where I and another player collided pretty violently. I got up and continued to play, even though I felt some discomfort. This happened about 8 weeks ago and I still have some discomfort in the outside, back of the shoulder joint. I don t believe it s a muscle injury because I can still work out doing push ups and shoulder presses. But I still have some discomfort in what feels like a tendon or ligament. Also, if I make a certain movement I will get a sharp pain, that is literally just for a second. That happens very sporadically. It seems to be getting better because when I do a shoulder workout I can complete the workout without any sharp pain . Is this a minor dislocation, or something else?
