I have a pretty persistent fungal issue. It doesn't seem to really matter how clean I keep things (clothing and myself) - I have to do a round of antifungal cream treatment about twice a year. Before I finally gave up and went to the doctor I must have had it over half my body, basically anywhere where sweat accumulated - under arms, feet, calves under socks, crotch, even in my sideburn area under a bit of hair and my helmet strap.

A few days of antifungal every 12 hours clears it all up. Sometimes I wish I could buy the stuff by the pint though.

When I've got it, it itches so bad that I almost can't stop before tearing the skin right off.
