I had a f/u the next day and my dr prescribed nitro bid, I have seen him multiple times for follow up, he believes the top part has circulation and the nipple and bottom part may slough off- I am worried that i will have a large open wound. One side of the Areola that is kind of a shiny brown, and my nipple and the left side of Areola are black and leathery. My nipple also seems to be flattening. What is the normal progression?
