I was plagued by yeast infections when taking cipro and flagyl. I got them in my leg pits mostly but a few were bad and spread all through my groin and underside of my scrotum. A combination of blow drying the area, Zeabsorb, and rotating onto xifaxin which is not systemically absorbed, knocked it out. I had a really bad one that spread because I was putting Desitin on it. My dermatologist told me it spread because Desitin has a high water content and I was just locking in moisture and feeding the fungi. I would see a dermatologist if it doesn't get better soon. There are antifungal pills and I took them once for the one that got real bad.
