I'm a 21 years old female and I've noticed a rash developing on my beasts. It began on my right side but now is on both breasts. The rash kind of look like pimples. Is this something that I should be worried about? It doesn't itch unless my nipple gets dry, and the rash is confined to my nipple. I do drink a lot of caffeine b/c i'm in school, and I'm also taking birth-control (tricyclin low). What should I do? Thanks!
