I am seven months pregnant and in the last two and a half weeks I've noticed several mole-like brown and black bumps developing on my nipples and the areola, only in the cracks, and it leads up to the ducts. There is no pain, itchyness, tenderness or swelling; unfortunately my nipples are virtually 100% numb and they get worse daily and I get more moles daily. What in the world are these bumps, what can I do about them and is there any way that the sensitivity will return to my nipples? Is there any chance this will affect breastfeeding? I'm getting so many some of them are starting to look like they run together and make bigger moles! I've had three other children and never seen or heard of anything like this before. Is it even pregnancy related?
