…plantar warts caused by the human papillomavirus (HPV).

Plantar warts are small growths that usually appear on the heels or other weight-bearing areas of your feet. They are caused by HPV, which enters the skin through tiny cuts, cracks, or breaks. While they are not typically dangerous, they can be painful and contagious, spreading to other parts of your body or to other people through direct contact or shared surfaces.

These warts often have a rough, grainy appearance and may feature tiny black dots—clotted blood vessels—on their surface. Over time, they can become embedded deeper into the skin, causing discomfort when walking or standing. Plantar warts are common among people who frequently walk barefoot in communal areas such as swimming pools, gyms, or locker rooms.

The virus thrives in warm, moist environments, making proper foot hygiene essential. Wearing flip-flops in public showers, keeping feet dry, and avoiding direct contact with warts—either your own or someone else’s—can significantly reduce your risk of infection.

Treatment options include over-the-counter salicylic acid solutions, cryotherapy (freezing), laser therapy, and minor surgical removal. In some cases, the immune system will clear the wart on its own, but this process can take months or even years. If a wart becomes painful, spreads, or persists despite home treatment, it’s important to seek medical advice from a dermatologist or podiatrist.

Although plantar warts are generally harmless, neglecting them can lead to discomfort, spread of the virus, and even secondary infections if the skin becomes damaged. Early treatment and preventive measures are key to keeping your feet healthy.

Remember: if you spot these growths on your feet, treat them promptly, maintain good hygiene, and protect others by covering the area until it’s fully healed.
