I have been having problems with both of my breasts again. Right side I figured out had a crack and the left side may also but the whole breast hurts off and on. No bumps and no red spots. Anyway, tonight I noticed a rash under my breast. Not on it, under it. Like on my stomach. It doesn't itch or anything though. I am very large chested (F). I googled and yeast infections came up but everyone talked about how badly they itched and I don't at all. Wth??
