I had this condition. My parents were told that "shepherds in the mountains that have never had human contact" have been found to have this condition. The prescription medication worked but was very expensive. Once I was "on my own" I couldn't afford it, but my first question was, "If shepherds didn't have human contact, how do we know they had it?" The doctor just gave me that stupid look. LOL
I have tried anti-fungal creme and it works wonders. Mostly mine pops up when it's warmer. Of course, I avoid the sun during treatment and until it's gone, because it's much more noticable after sun exposure.
Hope this helps. If you need more information, you can send me a private message.
