Plantar Warts/Foot Warts
A plantar wart is a skin lesion that develops in response to a viral infection of the skin on the sole of the foot. Plantar warts are similar to warts that occur on other parts of the body. Because they are on a weight-bearing part of the body, such as the foot, they are usually deeper and appear flat rather than elevated from the surface of the skin.
Plantar warts spread by increasing in size and/or forming "satellite" lesions in the same or other areas of the foot.
Most treatments involve using a topical chemical applied to the wart, surgical excision, or medication that is injected into the wart to weaken the virus so that the body's immune system can then eliminate the wart. Some warts respond quickly to treatment, while others require many weeks or months of repeated treatments to allow the lesion to resolve.
While there are some over-the-counter medications to apply to the wart, medical treatment should be sought to rule out other skin changes that can affect the foot.
