I have had a small, hard,left clavical bone lump for years and never bothered me. Recently, it started to become uncofortable and painful to the touch and has grown bigger and has gotten red. It isnt real hard, feels like a cyst but doesnt move. Since the sudden change, i have developed a case of "really bad stiff, sore, achy, neck as if you slept on it wrong and has not gone away. I also now have a cough. Feels tight in throat/neck area. There are other tiny, mild, "play it off due to other reasons or unexplained odd" symptoms that I have had that now concern me as to whether it all is related or not. Father passed of leukemia and mother has had thyroid cancer. mother side has had tuberculosis and a death from throat cancer. I dont wanna go to dr unneccesarily but could cancer be a possibility?
