I am a 13 year old male with one puffy nipple i started getting it when i was 11. i am not over?

weight or anything. This is really bothering me it is embarrassing to play sports with my shirt off and to swim. I need some answers to why this is happening to me and if possible please tell me when it will go away and what i can do to make it go away faster.

Jeff, most of us here aren't doctors. So my advise is to talk with your dad or your mom about seeing a doctor about this. Don't wait, this is too important to you.
