Warts are small growths that may occur anywhere on the body. Plantar is a term derived from a Latin phrase which means the sole of the foot. Plantar warts therefore are those that occur on the soles of the feet.
Plantar warts are caused by your body’s reaction to a viral infection that penetrates the skin of the foot. Once there, it may remain for many months before causing the development of the wart itself. Because of the pressure of body weight during walking, plantar warts tend to grow inward and develop hard callused tissue over them. Therefore, they often are confused with corns or calluses.
Warts contain many blood vessels and nerve endings, and can bleed profusely when cut. It is recommended that you never attempt to cut or trim plantar warts. Pressure against the nerve endings can produce considerable pain.
Warts can spread from one part of your body to another and may occur singularly or in clusters, and range in size from a small pinhead to larger than a half dollar.
Warts occur more commonly in younger age groups. It seems a certain degree of resistance or immunity is acquired by adulthood. Certain persons are more prone to develop warts, and it appears to be related to their general body defense mechanisms and immune status.
