I am very large chested and occasionally I do get heat rashes
under my breasts.. Usually I just treat it with some powder, keep the
area clean and dry as possible and within a few day's it goes away. Here lately, the rash underneath my right breast has increasingly gotten worse.. It is itching, and the skin is peeling, and it's bright red and it is so intense that it look's like it's scarring my skin..The parts that are healing, are turning a brownish color...
