Three weeks ago I contracted a painful (not itchy) rash in my upper inner thighs, where the leg folds into the groin, after a very sweaty day in the hot
heat, and lack of shower until the night. I assumed it was
jock itch, and accordingly began to treat it with lamisil. The medicine helped reduce the intensity of the rash, but it didn't fight it all the way off.
Soon, the rash became itchy (and remains itchy), and spread to my groin and, though not as heavily, my penis.
