Warts and verrucas are harmless skin growths caused by the human papillomavirus (HPV). Warts usually appear on the hands and fingers, and verrucas are warts on the soles of the feet.
What they look like
- Rough, raised bumps, often skin-coloured or slightly darker
- Small black dots (tiny blood vessels) within the surface
- On the feet, verrucas can be flattened by pressure and painful when walking
How they spread
The virus spreads through direct contact and from damp surfaces such as changing rooms and swimming pool floors. Warts are more likely to take hold on skin that is broken or soft from being wet.
Treatment
Many warts clear up on their own, although this can take months or even a couple of years. Pharmacy treatments containing salicylic acid can help if used regularly. If a wart is painful, spreading, bleeding or has not responded, or if you are unsure of the diagnosis, it is worth having it assessed. Other options may be discussed after examination.
Self-care
Cover verrucas with a waterproof plaster when swimming, avoid sharing towels and socks, and do not pick or scratch warts, as this can spread them.
When to seek advice
Seek advice if a growth bleeds, changes in appearance, is on the face or genitals, or if you have a weakened immune system or diabetes.
