I have been experiencing slight pain in my shoulder, right at where my collar bone and shoulder meet, front and top. It has been sensitive to the touch as well. The bone is protruding a bit or swollen at the top where the collar bone and shoulder meet. I frequent the gym 2-3 times a week. I have been icing and using a heating pad. Has not gotten any better, seems to be getting worse. Tonight after icing I have noticed the muscle on my shoulder, front inside is swollen. Any possible ideas on what I m looking at, before I go to the doctor?
