Warts are common growths that can develop on practically any part of the body, but especially on the hands and feet. Because they are caused by a virus, they can be spread to other areas of the body or to other people via shaking hands or walking barefoot in an area that someone else with a wart has stepped.
In some cases the body will eliminate warts without any treatment. In other cases, however, this does not happen and the wart(s) continues to grow, spread, and in some cases become painful. Luckily, several treatment options are available. Small and new warts sometimes resolve with a single treatment while many warts require multiple treatments.
