For about five weeks, I have had a red rash underneath and on top of my breasts, and extending down a little onto my stomach area. I have large breasts, so I am accustomed to some heat rash and discomfort at times, but this is more and very painful. Also, I have begun to itch (without a rash) on my scalp, arms, and legs and have no rhyme or reason. I have tried zinc oxide, calamine lotion, neosporin, Gold Bond itch creme, and Monistat chafing cream - no relief. I have changed nothing in my daily habits or eating habits!!
