itching breasts ?

Shelby

i have a problem i think? i’m not sure if it’s necessarily a problem but either way i could use someone wise to help answer some questions. my breasts tend to get get randomly itchy (especially around the nipple) and no matter how much i itch them it doesn’t stop until i don’t notice it anymore. some times when i itch them i even scratch too rough just trying to get them to stop itching and then red spotted marks were left over expanding out towards under my arms. it gets annoying after a while and i’m curious if it’s normal or not. i’m only 13 so my breasts are still developing and that may have something to do with it but i am still not sure. is this normal?
