I had my breast reduction 7/26/16 and had some major problems with my left nipple and areola. I lost my nipple, and I have a rather deep fistula. I keep having this disgusting, smelly discharge from the fistula, and my surgeon thinks it is fat necrosis. I'm getting super discouraged because it won't heal. How long does something like this usually take to heal up? I've been packing it twice a day with strip gauze. Thanks in advance!
