A plantar wart and callus are two different things. A callus is a thickening of the skin in an area of high pressure. The outer layer of the skin is "dead" but puts adds to pressure beneath the foot, often causing pain. Treatment for a callus includes padding and the safe removal of the dead skin, often by a foot doctor in Houston.

A planters wart is a manifestation of a virus on the foot, known as a verruca. A wart can occur anywhere, but a "plantar" wart is specific to the bottom of the foot. While a wart and callus appear similar, they are treated in different ways. A wart becomes intertwined with the healthy skin and is fed by blood vessels. The goal of treatment for a wart is to eliminate the wart tissue but preserve the healthy skin without injury or scarring.
