I also use a hairdryer, do not share towels with anyone, and have used Lamisil (
Terbinafine)
for 2 weeks as of today. I change my underwear once per day though, but I avoid sweating or walking much during the day as much as possible. And apply talcum powder on my groin every 2-3 hs during the day. That's all I've been doing and as I wrote, the skin at first sight looks back to normal, BUT if I see it from an angle, I can still see the circles where the jock itch used to be........
