I've had that before if you have Farley large breast you can sweat or just have moisture under your boobs and if it sits there too long it irritates the skin and can have a nasty stitch to it..when I first got it I panicked and my dr just said it's normal just clean area make sure the area is dry so then I started using baby powder under my boobs and it never happens anymore.
id just to get checked. like she said above, could be a moisture or fungal issue. ive had it happen before but mine was due to moisture. just to be on the safe side. but here lately I get chaffing bc of moisture and wearing wire supported bras.
Could be either just moisture or a fungal infection. I had it and my dr said it was a fungal infection. Get it checked out to be safe
double d and I stay in the water. I think it's my addiction lol
