Okay I've had these lumps under my nipples about half way through 7th grade and still have them at the end of 9th grade. I saw the doctor about it and he said just leave them alone. There really annoying and I've been rubing them. They kept getting bigger now my left one is small and recently my right one EXPLODED!! No joke I don't know how to explain it but I would love to know how to get rid of them. I've been trying not to rub them but nothing is happening!
