What is verruca?
A verruca is a small, rough lump on the sole of the foot caused by the human papillomavirus (HPV). Verrucas are harmless but can be uncomfortable or painful when walking. They usually have tiny black dots in the centre (clotted blood vessels) and a hard, cauliflower-like surface. Most verrucas clear up on their own within months or years without treatment.
When NHS resources suggest seeing a GP
- The verruca is painful or bleeding
- The verruca changes appearance or spreads
- You have diabetes (foot problems need extra care)
- You have a weakened immune system
- Self-care treatments have not worked after several months
- You are unsure whether it is a verruca
Self-care information from NHS
- Cover the verruca with a waterproof plaster when swimming
- Avoid walking barefoot in public places like pools and changing rooms
- Do not share towels, socks, or shoes
- Try over-the-counter salicylic acid gels, creams, or plasters from a pharmacy
- Soak your foot and gently file the verruca with a pumice stone once a week
- Do not pick at the verruca — this can spread the virus
Common questions
How long does a verruca take to go away?
Most verrucas clear up on their own, but this can take months or even up to 2 years. Treatment can speed up healing but is not always necessary, especially if the verruca is not painful.
Are verrucas contagious?
Yes. Verrucas are caused by HPV and can spread through direct contact or contaminated surfaces like swimming pool floors. Cover the verruca with a waterproof plaster in public wet areas to reduce the risk.
What is the difference between a verruca and a wart?
A verruca is simply a wart on the sole of the foot. The pressure from walking pushes it inward, which is why verrucas can look flat and feel painful, unlike raised warts on other parts of the body.
Can I treat a verruca at home?
Yes. NHS resources describe over-the-counter salicylic acid treatments and freezing kits from pharmacies as reasonable self-care options. Always follow the product instructions, and speak to a pharmacist or GP if unsure.
When should I see a GP about a verruca?
See a GP if the verruca is painful, bleeds, spreads, changes appearance, or if you have diabetes or a weakened immune system. Self-care treatments that do not work after several months are also worth discussing with a healthcare professional.
