What would cause pain in my shoulders and arms? For the past 3+ months, I have been getting sharp pain in my shoulders at the point where the clavicle, humerus, and scapula meet. I also have pain in my lower arm and elbow. This pain came on suddenly and has been consistent. It becomes worse at night and eases during the day. It is also painful in my upper arms to raise my arms straight out to the side sometimes. It seems my range of motion is limited. I have been taking aspirin for the pain and attempting stretching exercises.
