Nipple Pimple?

Meaghan • don`t look backwards or you`ll fall down the stairs.
This is super embarrassing but I have pimples on my nipples. I have acne, but this is different and weird. Should I be concerned? Do other people have this? I feel like ever since I've had breasts they've been there. They just make me feel uncomfortable and weird. Not that anybody can see them or anything. Is this normal?
