Plantar Warts

Plantar warts are common viral skin infections that occur on the bottom of the foot. Infection is promoted by breaks in the skin and warm, moist conditions. Walking around public showers or locker rooms in bare feet is a common risk factor for plantar warts. The warts resemble calluses but can have small black dots that are capillary endings.

Warts will usually disappear by themselves, but you should seek treatment if they cause pain. Your physician may recommend the use of salicylic acid patches or may remove it by freezing it with liquid nitrogen or cutting it off.
