A plantar wart problem

Wart is from viruses: Vague question, but a wart is a skin lump caused by papilloma viruses (it sometimes spreads to other people). A corn is a lump of dead skin cells formed where there is repeated pressure or friction on the skin (happens without viruses). Both lumps can push into the bottom of a foot because on the sole, a person stands or walks on the lumps all day.
