About two years ago, when I was 12, I noticed small lumps under each of my areolas. I asked a few of my friends about it and one of them was experiencing the same sore, rubbery lumps. After about a year, the soreness and the lumps left, but then it caused my areolas to expand and puff out. I can still feel a pillow of tissue under each one, and it makes me self-conscious. I've heard different things about it, that its gynecomastia or a strange disease which has to do with X & Y chromisones, but I'm not sure.

I would greatly appreciate any advice you could offer. I'm hoping this will clear up within a year.
