Hey, I'm 14 years old and for the last few days my right nipple/breast has been hurting. It feels like there is some sort of lump or growth or something underneath it that is hardish to the touch and also hurts. I'm freaking out because I have no idea what it is and don't see my mom for the next couple days to ask her about it. Plus I'm terrified to ask her. Please help!

If this helps any, I started my period when I was 11. Idk If that helps any, but maybe it has something to do with hormones...? Idek
