Okay, so this isn't necessarily pcos related, but hoping someone out there can help. Lately I've developed a kind of rash under my breasts. I know it is from it being so hot and now that I am bigger, the fold under my breast is too and it is from sweating so bad there and having my bra rub. Any suggestions from anyone. I have already tried using baby powder to absorb the extra sweat and I even decided to try my son's desitin to see if that would help. It is getting pretty painful under there.
