Hi Doc I have a very tender indentation on my left side in rib cage. Pain radiates in back of should blade and in front. Had chest X-ray...all is good. I had a bad fall a year ago and broke my left elbow. Could this be related. It is so very tender and flares up and gets worse at times. The indentation is alarming me. Can you help? Ive read about slipped ribs and nerve damage? I have also have a couple of chest exams because sometimes the pain radiates thru the from of my left chest. All checked out good there too.
