lanza Redness and soreness under your breasts is because two folds of skin are perhaps together trapping the dampness between - it can also happen in the groins - it is called intertrigo. In the UK there is a cream for this may be on prescription called TIMODINE - speak with your Doctor or pharmacist. When you wear a brassiere this separates the skin but at night the skin folds are together unless you wear a night bra. Ordinary emollient cream will help but important that you separare the folds of skin with gauze after applying even a piece of cotton it's a bit like nappy rash.     

sorry i'm not a doctor , but could it possible be breast cancer, why take chances get to a doctor as soon as possible..

Boraxo soap produces a rash when used in the laundry. Boric acid, well water filtered through sea sand, fiber glass insulation, old velvet that is rubbed off easily, dry rotted wood and many dusty types of plants, grasses and pollen can produce a rash and or intense itching.   Washing clothes in machines that have been used to wash rugs or carpeting can produce itchy clothing.  

sounds like a form of sweat rash but I would get it checked out with your Doctor

It might be breast cancer

could be a fungus from trapped perspiration. See a dermatologist, then go to your gyn , or  your family Dr. and ask him/ her for a mammo gram.- - - - since you mentioned pain, too

This must be very uncomfortable for you.  Why not ask your doctor?
