I had a double mastectomy 5 weeks ago. At first the incision looked good. after a couple weeks notice a split with a black scab. My doctor gave me silver sulfadiazine cream applied once a day and covered. It looks now like something is eating at my skin. Feels like its burning. Could I be having a reaction to the cream. Doctor now wants to go back in surgery to cut infected and dead skin off and reclose. He plans on taking some saline out of implant. My other breast is starting to do the same thing
