hi, i have a small rash in my cleavage (consisting of a few small spots and a pale red colour) which is very itchy when i am wearing a bra as my breasts are pushed very closely together! when i dont have a bra on the rash doesnt bother me at all. i was just wondering what could be causing this and what home remedies i could use to clear it up quicker? in my opinion, i feel it could be a sweat rash but not entirely sure thanks in advance
