A health care provider usually diagnoses a plantar wart by looking at it or cutting off the top layer with a scalpel and checking for dots. The dots are tiny clotted blood vessels. Or your health care provider might cut off a small section of the growth and send it to a lab for testing.


Most plantar warts are harmless and go away without treatment, though it may take a year or two in children, and even longer in adults. If you want to get rid of warts sooner, and self-care approaches haven't helped, talk with your health care provider. Using one or more of the following treatments may help:

  • Freezing medicine (cryotherapy). Cryotherapy is done in a clinic and involves applying liquid nitrogen to the wart, either with a spray or a cotton swab. This method can be painful, so your health care provider may numb the area first.

    The freezing causes a blister to form around your wart, and the dead tissue sloughs off within a week or so. Cryotherapy may also stimulate your immune system to fight viral warts. You may need to return to the clinic for repeat treatments every 2 to 3 weeks until the wart disappears.

    Possible side effects of cryotherapy are pain, blisters and permanent changes in skin color (hypopigmentation or hyperpigmentation), particularly in people with brown or Black skin.

  • Stronger peeling medicine (salicylic acid). Prescription-strength wart medications with salicylic acid work by removing a wart a layer at a time. They may also boost your immune system's ability to fight the wart.

    Your health care provider will likely suggest you apply the medicine regularly at home, followed by occasional office visits. It might take weeks to remove the wart using this method.

Surgical or other procedures

If salicylic acid and freezing medicine don't work, your health care provider may suggest one or more of the following treatments:

  • Minor surgery. Your health care provider cuts away the wart or destroys it by using an electric needle (electrodesiccation and curettage). This method can be painful, so your health care provider will numb your skin first. Because surgery has a risk of scarring, it's not often used to treat plantar warts unless other treatments have failed. A scar on the sole of the foot can be painful for years.
  • Blistering medicine. Your health care provider applies cantharidin, which causes a blister under the wart. You may need to return to the clinic in about a week to have the dead wart clipped off.
  • Immune therapy. This method uses medications or solutions to stimulate your immune system to fight viral warts. Your health care provider may inject your warts with a foreign substance (antigen) or apply a solution or cream to the warts.
  • Laser treatment. Pulsed-dye laser treatment burns closed (cauterizes) tiny blood vessels. The infected tissue eventually dies, and the wart falls off. This method needs to be repeated every 2 to 4 weeks. Your health care provider will likely numb your skin first.
  • Vaccine. HPV vaccine has been used with success to treat warts even though this vaccine is not specifically targeted toward the wart viruses that cause plantar warts.

If a plantar wart goes away after treatment and another wart grows, it could be because the area was exposed again to HPV.

Lifestyle and home remedies

Many people have removed warts with these self-care tips:

  • Peeling medicine (salicylic acid). Nonprescription wart removal products are sold as a patch, gel or liquid. You'll likely be instructed to wash the site, soak it in warm water, and gently remove the top layer of softened skin with a pumice stone or emery board. Then after the skin has dried, you apply the solution or patch. Patches are often changed every 24 to 48 hours. Liquid products are used daily. It might take weeks to remove the wart using this method.
  • Freezing medicine (cryotherapy). Nonprescription medicines that freeze the wart include Compound W Freeze Off and Dr. Scholl's Freeze Away. The Food and Drug Administration cautions that some wart removers are flammable and shouldn't be used around fire, flame, heat sources (such as curling irons) and lit cigarettes.
  • Duct tape. Using duct tape to remove warts is a harmless but unproven approach. To try it, cover the wart with silver duct tape, changing it every few days. Between applications, soak the wart and gently remove dead tissue with a pumice stone or emery board. Then leave the wart open to the air to dry for a few hours before covering it with tape again.

In general, no matter which treatment you try, do these two things:

  • Cover the wart to help prevent it from spreading to other parts of the body or to other people.
  • Wash your hands after touching the wart.

If a plantar wart goes away after treatment and another wart grows, it could be because the area was exposed again to HPV.

Preparing for your appointment

You'll likely start by seeing your primary care provider, who may then refer you to a specialist in disorders of the skin (dermatologist) or feet (podiatrist). The following tips can help you prepare for your appointment.

What you can do

Bring a list of all medications you take regularly — including nonprescription medications and dietary supplements — and the daily dosage of each.

You may also want to list questions for your health care provider, such as:

  • If I have a plantar wart, can I start with at-home care?
  • If I use a home treatment, under what conditions should I call you?
  • If the first treatment doesn't work, what will we try next?
  • If the growth isn't a plantar wart, what tests do you need to do?
  • How long will it take to get results?
  • How can I prevent warts?

What to expect from your doctor

Your health care provider may ask you questions such as:

  • When did you first notice the wart?
  • Has it changed in size, color or shape?
  • Is your condition painful?
  • Have you had warts before?
  • Do you have diabetes or poor sensation in your feet?
  • Do you have any condition or take any medication that has weakened your ability to fight disease (immune response)?
  • Have you tried any home remedies? If so, how long have you used them and have they helped?
  • Do you use a swimming pool or locker room — places that can harbor wart-causing viruses?

What you can do in the meantime

If you're sure you have a plantar wart, you may try nonprescription remedies or alternative medicine approaches. But talk with your health care provider before trying self-care treatments if you have:

  • Diabetes
  • Poor sensation in your feet
  • Weakened immunity

If pressure on the wart causes pain, try wearing well-cushioned shoes, such as athletic shoes that evenly support the sole and relieve some of the pressure. Avoid wearing uncomfortable shoes.
