My shoulder is KILLING ME right now! Please help?

Well sounds like burcitos in your rotar cuff. Do u do sports? If so that's what causes it. I have burcitos and iknow it's very painful and it won't go away tell you go to a physical therapist to have them give you excersises. If you don't take care of it you'll never be able to do sports again till it's not inflamed anymore wich will take a while. I suggest not moving ur arm for about 3 weeks. You might not be able to Start the excersises for a month.
