I am 16 years-old girl. And one day, out of no where, I got what looks like a rash on both my nipples. It got to the point where I scratched so hard they bled, though I think that was my own fault. And this morning they hurt, I couldn't even put on a bra. When I look at them they look scaly, like if they were chapped and in need of moisturizing, but no matter how much lotion I put on, they still itch and the skin still flakes. I thought that maybe it was just some form of allergy to my bra. I changed to all cotton type of bra's and it still didn't stop the itch. I later read that it was common in women who were lactating... I'm not pregnant nor have I given birth, I'm not even sexually active! I also read that it could be from menstruation. And I did get my period a month after (I didn't get my period the month I got the rash.) the rash came to be. I'm confused and scared. I've read it could be cancer... I really don't want to think about that possibility just yet. Can someone please help me?
