Wart(s)

What Kinds of Warts Occur on the Feet?

Warts are caused by a virus called HPV or human papillomavirus. They are quite common, affecting approximately seven to 10 percent of the population. The virus causes skin cells to increase and grow more thickly, leading to the characteristic circular bulge in the skin. They can be spread from one area of the body and in some cases can burrow under the skin and cause pain. Plantar warts (warts on the bottom of the foot) are probably the most common warts on the feet.

How Are Warts on the Feet Treated?

Warts, especially plantar warts, can be difficult to treat and tend to recur. Treatments include the use of cryotherapy (using liquid nitrogen to freeze off the wart) and topical medications like salicylic acid, which are usually applied and then dressed with an occlusive dressing. Medications may be injected directly into the wart to kill the virus. In some cases, especially in the case of deep burrowing warts that cause significant pressure or pain, surgery is necessary.

How Can a Podiatrist Help?

Although in many cases, a wart is not a matter of great concern (although it may be unsightly or uncomfortable), some skin cancers can present with a wart-like appearance. A podiatrist can identify these suspicious lesions and perform a punch biopsy to confirm whether there are any abnormal cells. Podiatrists can also provide or perform any of the standard treatments for warts.

Can I Prevent Warts on My Feet?

HPV typically thrives in warm, moist environments, like public swimming pools and locker rooms. The virus is transmitted by direct contact and may be more likely to cause an infection if the patient has small cuts or abrasions on the skin. Wearing water shoes can help protect the feet, and if there is an option to use a decontamination foot bath, it can help prevent the spread of the virus. Feet should be washed with soap and water and dried at least once a day; socks should be changed at least once a day.
