Hey Doc, I have mild soreness in the area between of my right clavicle and right shoulder. It has been sore for approximately 4-5 weeks. I have full range of motion with my shoulder and arm, and actually it bothers me more after resting on that particular side of my body when sleeping. the discomfort actually woke me up during the night. I ve suffered no fall or hits to that area. Although I did lift a lot of heavy stock boxes during that initial timeframe of the first I noticed the pain. scale of 1 to 10 (a max of 2 at least last evening). Question could it just be strained ligaments in that area?
