Plantar warts are caused by a virus that is most commonly found in warm, moist environments like pools and public locker rooms, but can be found in carpets and other hard surfaces. Usually the skin is enough of a barrier to protect you from getting a wart however some people are just more susceptible to warts. A small break or scratch in the skin is a perfect entry point for the virus. Once the virus invades the skin, you will start to feel a hard lump forming, followed by changes in the skin appearance. Warts are contagious and often multiply and spread to the surrounding tissues.
Warts are more common in children and young adults, but may present at any age. If left untreated, warts often spread and become unsightly and painful to walk on. A variety of conservative treatments are available for plantar warts. Surgical removal is not usually recommended.
