Plantar Warts: Treatment and Prevention
Plantar warts (verrucae) are rough growths on the sole caused by the human papillomavirus. They are harmless but can be painful and persistent, especially when they grow inward under pressure.
What plantar warts are
Plantar warts develop when HPV enters the skin of the sole through tiny cuts, often picked up on damp communal floors. Because they grow inward under body weight, they can feel like a stone in the shoe and may show tiny black dots (clotted blood vessels).
Wart or corn?
A handy test: warts interrupt the skin's natural lines and are painful when pinched from the sides, while corns leave the skin lines intact and hurt more with direct downward pressure. If you are unsure, a podiatrist can tell them apart.
Treatment options
Many plantar warts clear on their own within months to a couple of years. To speed things up, over-the-counter salicylic-acid treatments used daily after filing, and cryotherapy (freezing), are the mainstays. Stubborn warts may need stronger clinic treatments. The NHS notes that warts often resolve without treatment and that no method guarantees a cure.
Preventing spread
Wear flip-flops in communal showers and around pools, keep the wart covered, do not share towels or socks, avoid scratching or picking, and keep feet dry. Treat your own warts before they multiply.
