Hard & puffed out nipples
I've had this hardish tissue behind my nipples for about 4 years now. One more than the other. This makes them puff out and protrude about 5/8 of an inch on the right one. It is getting to be really embarrassing. I'm 16, 5'7, 136, I'm moderately skinny. I wear small shirts and my nipples noticeably stick out. My pediatrician told me they would've gone away eventually 4 years ago, but I see no signs of improvement. I thought maybe developing chest muscle by going to the gym would help, but it didn't. Is it likely for it to leave on its own, or do I have to get them removed?
