Right before I got dark patches of skin under my breasts (and stop right here if you do not like TMI) I was getting really sweaty (hot flashes) and my breasts would have a sweetish smell. Anyway, I thought about it, and I looked up rashes on the internet. I'm wondering if the dark patches under my arms and under my breasts might be from yeast/candidia - and maybe is related to IR??? or having too much sugar in one's body....anyway as an experiment, I tried using some clormitazole (sp??) the cream you use for athlete's foot/jock itch...under my breast area and under my arms (3 days now), and it seems to be helping a little. So, not sure if this will be helpful to anyone, but what's there to lose???
