I'm not so sure that a fungal skin infection isn't related to systemic yeast overgrowth. I've had these fungal skin spots that would show up on all the moist places on my body for over ten years now. Since they were mild and they didn't itch or hurt, I just applied tea tree oil and they would eventually go away, only to pop up again in another month or two somewhere else. Finally I had one that didn't seem to respond to tea tree oil and it wouldn't go away. Now that I've finally gotten serious about dealing with my yeast/fungal overgrowth, even the most stubborn one has gone away. When I cheat on my diet (for me that means cheese!), they pop back up again. So it seems clear that they are a symptom/result of yeast overgrowth in my body.
