I am 3 weeks post op from breast reduction surgery. Since the 2 week mark, I've developed a red, itchy rash. All tape is off, Lotrimin for 3 days, didn't work. Now trying hydrocortisone, but it's only the second day. No improvement. All incision lines are red as well. Today I took Benedryl, hoping for some itch relief. Any advice will be appreciated.
