Warts

What are plantar warts?

Plantar warts are viral skin growths that appear on the soles of the feet. Unlike common warts that grow on the hands or fingers, plantar warts grow inward due to pressure from walking or standing. This makes them particularly uncomfortable and sometimes painful.

What causes plantar warts?

Plantar warts are caused by HPV entering the skin through small cracks or breaks. The virus thrives in warm, moist environments such as public showers, locker rooms, and swimming pool areas. Not everyone exposed to HPV develops plantar warts — it depends on your immune system’s response.

What are the symptoms of plantar warts?

Typical signs of plantar warts include:

• Small, rough lesions on the sole of the foot
• Black pinpoint dots (clotted blood vessels)
• Callused or thickened skin over the wart
• Tenderness when walking or standing
• Lesions that interrupt the normal lines of the skin on your foot

How are plantar warts treated?

Treatment options include:

• Prescription-strength salicylic acid treatments
• Cryotherapy (freezing the wart with liquid nitrogen)
• Laser therapy to destroy wart tissue
• Minor surgical removal when conservative care fails
• Immune-boosting medications to help fight the virus

Some warts resolve on their own, but many persist and require podiatric care for full removal.

Can plantar warts come back?

Yes. Because plantar warts are caused by a virus, they may reappear after treatment, especially if the immune system is weakened or the feet are frequently exposed to contaminated surfaces. Proper foot hygiene, wearing shoes in public areas, and following your podiatrist’s aftercare instructions can help reduce recurrence.

Are plantar warts contagious?

Yes. Plantar warts can spread through direct contact with the virus, often in warm and damp places like locker rooms or pools. They can also spread to other parts of your own feet if untreated.

How do I know if I have a plantar wart or a corn?

Plantar warts often have black dots and disrupt the natural lines of the skin, while corns are simply thickened skin from friction. A podiatrist can confirm the difference with an exam.

When should I see a podiatrist for plantar warts?

You should seek care if the wart is painful, spreading, interfering with walking, or not improving with over-the-counter treatments. Diabetic patients should always see a podiatrist promptly for any foot lesion.

Can children get plantar warts?

Yes. Children and teenagers are more likely to develop plantar warts because their immune systems are still building defenses against HPV. Treatment helps prevent spreading to family members and classmates.

Do plantar warts always need treatment?

Not always. Some plantar warts go away on their own, but many persist for months or years and can become painful. Professional treatment ensures safe and effective removal.
