My "friend" thought it would be funny to punch me in the right rib so hard that it started to hurt. It doesn't hurt when I breathe or cough or sneeze but when I sit, it feels swollen. And I also noticed there is a small dent in my chest, the exact spot a doofus punched me. Did it crack or break? Or is it just a minor bruise? Do I need to see a doctor? Please help Yahoo Answers!
