The drug Podofilox used for genital warts when accidentally applied to the unaffected areas is very painfull and basically a burning of the skin. Any advice on what to apply to get rid of the pain?

A topical ointment. Same thing you would put on a cut. Polysporne is what I use. It is a chemical burn, not unlike a fire burn, and should be treated as such.

Cortaid or Cortizone might be another - ones that start with cort, short for cortisone.
