Still having problems after sternum fracture after 4 years...I get the same answer from every doctor I see; even after x-rays, the bone will heal on its own. Its something I have to learn to live with, nothing is wrong and I need not to worry or become anxious. However, whenever I lift washing clothes or many simple tasks, the sternum area (especially on the left side of chest) will swell up the size of a cell phone and is very visible and painful. Doctor says just put heat on it. I am new on your site and noticed a condition called Costochondritus. Could this be happening to me and if so, how do I approach a physician who continues to tell me I have nothing to worry about. I would appreciate suggestions that I may print to back up my concerns. Thank You
