Several years ago I was playing softball on the company team. I dove for a catch in short right field and didn't think anything about.....until the next day. My chest and back both hurt like the dickens. Went to my D.O. after several days of the pain getting worse and he let me know that I had dislocated 3 ribs. He also bent me around some and they popped back in. By that evening everything was back to "normal".
