My husband has wound separation on his lower left leg near his knee from a surgery he had over two decades ago. He had surgery to prevent his left leg from continuing to grow at a faster rate than his right leg and the doctors performed a skin graft. He experiences frequent scabing, and bleeding at the site of the wound, sometimes to the point of bleeding through his pant leg. He is an avid runner and the wound does not cause pain, but is a constant struggle otherwise. My question is- what sort of doctor or specialists should we see and what kind of treatment can we anticipate ?
