I HATE pain that can't be identified! I too, have an area between the clavicle area. About 1 inch down. It hurts to lay on my side because of the pressue it puts on it. I have been taking 2 Darvocett about 2-3 times aday. That seems to help, it sure helps with the arthritis stuff. But on every scan nothing shows up. Dr said it could be from the radiation I had in that area at the beginning of last year?? Not sure-but I, like you, want to know what it is!
