Four weeks ago I crashed my bike and landed on my shoulder. I have full range of motion of the arm with the only major pain occuring when I cross my body with the injured arm/shoulder. The shoulder was xrayed and I was told I did not break the collar bone. I have a large marble size bump on my collarbone, some pain in the shoulder muscles, and it feels like the bone is moving separately beneath the bumpwhen I raise my a arm over my head. Do I need to have another xray out am I just impatient?
