So I broke a bone in my foot. Have stayed off it for 6 weeks and with no shown improvement my doc is sending me back to work... I have also noticed that my piercings healed like around the metal but I took a set of piercings out 2 yrs ago and I just recently noticed that the holes were still there and the jewelry slipped back into the holes with no problem is there a medical explanation? Is it possible that I just don't heal?
