I have a rash on the inner sides of both breasts that both look like giant hickeys. they do not itch or burn and d not have any texture?

The most likely : cause would be a candidal skin infection. It is a bit puzzling that it does not itch or irritate at all. A quick look by a physician is probably in order. Over-the-counter antifungal creams that are often recommended include clotrimazole (Mycelex), miconazole (Monistat), and tioconazole (Vagistat). This type of treatment can kill Candida and reduce the spread of the infection.
