Plantar warts consist of small, rough growths that develop on the bottoms of the feet. Though contagious, they typically aren't serious, and a foot doctor may easily treat them. Here's what to know about this condition and how to avoid problems. 

Causes and Symptoms

Plantar warts develop as a result of an infection caused by human papilloma virus (HPV). When this virus enters tiny cuts, breaks, or weaknesses in the skin, small, rough growths may form, often on the heels, balls of the feet, or bases of the toes. They might appear lighter than the skin around them and have black pinpoints, which are small, clotted blood vessels. The growths can also cause pain and tenderness while standing or walking.

How They Spread

If the virus beneath the skin spreads, it may cause clusters of warts to form on the soles of the feet, known as mosaic warts. Though not common, the virus may spread to other people as a result of direct contact. Since the virus that causes plantar warts thrives in warm, damp environments, such as pool areas and locker rooms, walking around barefoot in these spaces can result in transmission. 

Treatment and Prevention 

Though plantar warts usually go away on their own, a foot doctor can typically expedite the process with cryotherapy, which involves applying liquid nitrogen to the affected areas. This causes blisters to form around the growths and stimulates the immune system to fight off the infection. Alternatively, a foot doctor may use salicylic acid to remove them one layer at a time and boost the body's immune response to accelerate healing. 

Washing the hands after making contact with warts may reduce the likelihood of contracting them. If you ever develop one, try not to pick or scratch at it, as this can cause clusters to develop. Keeping your feet clean and dry is one of the most effective prevention tactics. Additionally, avoid walking around barefoot, especially in pool areas and locker rooms. Every few months, swap out pumice stones and emery boards that you use on your feet, and sterilize nail clippers to lower the risk of making contact with HPV.
