I am sixteen, and I am nursing my infant son. About four weeks ago, I noticed a rash developing on my left breast. I didn't think anything of it, and just put anti inch cream to stop the itch and soreness. It slowly starting spreading and now covers my breast. There is also red pimple looking things on my niple. I went to my doctor yesterday, but he really didn't look at it, he just gave me a cream, and said that it is probably some type of fungus. But then I received an e-mail about Paget's disease, and am concered. Can you give me more information?
