Warts and verrucas

Warts and verrucas are small lumps on the skin. Most people have them at some point in their life. They are caused by a virus. They usually go away on their own but it may take months or even years.

Check if you have a wart or verruca

Warts and verrucas come in different shapes and sizes.

Common warts

A common wart may be round or oval-shaped and feel firm and rough. It sometimes looks like a tiny cauliflower.

Warts usually appear on palms, knuckles, knees and fingers, but they can appear on other parts of the body too.

Verrucas (plantar warts)

Verrucas are usually on the bottom of your feet. They are usually flat and have tiny black dots under the hard skin.

Plane warts

Plane warts are round, flat and can be yellow, brown, or pink in colour. You can have many of them. Plane warts mainly affect the hands, face and legs.

Genital warts

Genital warts are a common sexually transmitted infection (STI). You can get it from any kind of physical or sexual contact of the genital area - even if you use a condom.

Sexual contact includes:

  • any skin-to-skin contact of the genital area
  • vaginal, oral or anal sex
  • sharing sex toys

They can be treated by your GP or at an STI or GUM (genitourinary medicine) clinic.

Treating warts

Warts do not cause you any harm. Some people find them itchy or painful.

Non-urgent advice: Talk to your GP if:

  • you're worried about a growth on your skin
  • you have a wart or verruca that keeps coming back
  • you have a large or painful wart or verruca
  • a wart bleeds or there's a change in how it looks
  • you have a wart on your face or genitals

Salicylic acid

You can buy creams, plasters and sprays that contain salicylic acid from your pharmacy. These treatments can take up to 3 months to work.

They may irritate your skin and do not always work.


Do not use these treatments on your face.

Freezing a wart (cryotherapy)

Your GP freezes a wart or verruca so that it scabs over. Usually it falls off a few weeks later. This may take a few sessions. Your GP may prescribe creams or other treatments if freezing does not work.

How to stop warts and verrucas spreading

Warts and verrucas can be spread through skin-to-skin contact or contaminated surfaces with the virus. You're more likely to spread a wart or verruca if your skin is wet or damaged.

It can take months for a wart or verruca to appear.


  • wash your hands after touching a wart or verruca

  • change your socks everyday if you have a verruca
