Plantar warts are painful growths on the bottom—heel, sole, or ball—of the foot. Warts are caused by HPV (human papillomavirus) and can develop on their own or in clusters. Plantar warts often grow deep into the foot, are a common cause for foot pain, and can bleed if they are scraped.

The virus that causes plantar warts usually is transmitted by walking barefoot on a contaminated surface, such as a locker room floor or the deck of a swimming pool. Treatment for plantar warts is an important part of foot care and may include acid applications, surgical wart removal, cryotherapy, and laser treatments.
