HI, I just turned 16 years old, and for about 3 months one of my nipples has been puffy, it feels like a soft/firm lump is under it.
I've had this before, on both nipples 2 times. And both times it went away, and and this time it came back only on one nipple. It's never lasted this long either.
By the way, I AM a late bloomer, my voice as recently changed, and I'm finally starting to grow armpit hair.
I've already heard that the puffy nipples are from puberty, it's "breast tissue" that forms in 60% of boys when they go through puberty... I just want to know if I should be worried because it's lasting so long.
