I had a tender lump at the end of my right clavicle (at base of neck) that was very tender. Saw doctor who ordered a cat scan (?), everything looked fine. She had a surgeon look at it, both said it was unusual but not sure what it was. Suggested anti-imflammatory for a month. I now have another lump and swelling further up the clavicle, towards the shoulder. This one is not tender, and it tends to move around when I press on it. The other lump is hard like bone. What should be the next step?
