The only bad thing that has happened to me is that I got a staff infection from one of my incisions. I will also state that this is completely my fault as well. I waited too long to get my sutures out and was way too active way to fast. I went back to work after three days and was climbing stairs and putting more pressure on my body then what I should have. The one major piece of advise that I can give you is to slow down and follow your doctor's orders. In hindsight, I wished I would have followed the instructions completely.
