In brief: If you have both

Jock itch and athlete's foot, you have fungal spores on most of your clothes, which don't wash out and are not killed in the heat of a drier. So it might be best to go on an oral medication to get rid of this.
Lamisil (terbinafine) has a very long half life and a 2 week treatment will stay in your system for 30 days, the time needed to treat fungal infections, since spores live for 30 days. See a dermatologist.
