That small rough patch on the sole of your foot might be causing more worry than pain. Verrucas are one of the most common conditions we see at our Finglas clinic, and the question patients ask most often is simple: do I actually need to treat this? The answer depends on several factors, and getting it wrong in either direction can mean unnecessary treatment or prolonged discomfort. This post covers what causes verrucas, when treatment makes sense, what options actually work, and when you should see a podiatrist in Dublin.
What causes verrucas?
Verrucas are caused by the human papillomavirus (HPV), which enters the skin through tiny cuts or breaks in the outer layer. The virus thrives in warm, moist environments, which is why swimming pools, gym changing rooms, and shared showers are common places to pick one up.
Not everyone who comes into contact with HPV develops a verruca. Your immune system plays a significant role. If your immune response is strong, it often fights off the virus before a verruca forms. If your immune system is suppressed or simply has not encountered that particular strain before, the virus can take hold and cause the characteristic rough, hard growth.
Children and teenagers tend to get verrucas more frequently than adults. This is partly because their immune systems have not built up resistance to as many HPV strains, and partly because they spend more time in barefoot environments like swimming lessons and sports halls. Direct skin-to-skin contact can also spread the virus, though this is less common than environmental transmission.
Walking barefoot on rough surfaces can create the micro-abrasions that allow HPV entry. Once the virus is in the skin, it causes rapid cell growth in the outer layer, forming the raised, grainy texture you see on the surface.
What are the symptoms of a verruca?
A verruca typically appears as a small, rough, grainy lesion on the sole of the foot. The surface often has tiny black dots, which are small blood vessels that have grown into the verruca. Unlike corns, which develop over bony prominences due to pressure, verrucas can appear anywhere on the foot.
Pain varies considerably. Some verrucas cause no discomfort at all. Others, particularly those on weight-bearing areas like the heel or ball of the foot, can feel like walking on a small stone. Squeezing the verruca from the sides often produces sharper pain than direct pressure, which helps distinguish it from a corn.
If your verruca is multiplying, growing larger, becoming increasingly painful, or has been present for more than two years without signs of clearing, it is time to stop waiting and book an appointment. The same applies if you are unsure whether the lesion is actually a verruca or something else requiring different treatment.
How is verrucas treated at Foot Focus Podiatry?
Treatment at Foot Focus begins with a thorough assessment. Our CORU-registered podiatrists examine the lesion, confirm the diagnosis, and discuss your symptoms, how long the verruca has been present, and any previous treatments you have tried.
The decision to treat depends on several factors: pain levels, how long the verruca has been there, whether it is spreading, and your personal preferences. For verrucas that are not causing problems, watchful waiting is often appropriate. Most resolve within two years as the immune system eventually recognises and clears the virus.
When treatment is indicated, we use evidence-based approaches. Debridement removes the hard outer layer, allowing any topical treatments to penetrate more effectively. Acid-based treatments, applied professionally and at higher concentrations than over-the-counter products, work by gradually destroying the infected tissue while stimulating an immune response.
For stubborn verrucas that have resisted other treatments, cryotherapy using liquid nitrogen freezes the affected tissue. This method can be uncomfortable during application but is often effective for persistent lesions.
Treatment timelines vary. A small, recent verruca may clear within a few weeks. Long-standing or multiple verrucas may require several months of treatment. We set realistic expectations from the start and monitor progress at follow-up appointments.

What patients in Stillorgan are asking about verrucas
Q: Can I go swimming with a verruca?
A: Yes, you can swim with a verruca if you cover it with a waterproof plaster or verruca sock. This reduces the risk of spreading the virus to others. Remove the covering after swimming and dry your feet thoroughly.
Q: How long does verruca treatment take to work?
A: Treatment duration depends on the size, depth, and age of the verruca. Small, recent verrucas often clear within 4 to 6 weeks of treatment. Long-standing or deep verrucas may take 3 months or longer to resolve completely.
Q: Should I treat my child’s verruca or leave it alone?
A: If your child’s verruca is not painful and not spreading, leaving it alone is often reasonable. Their immune system will usually clear it within two years. Treatment is recommended if it causes pain, multiplies, or your child is self-conscious about it.
Q: Why do verrucas keep coming back after treatment?
A: Verrucas can recur if the virus was not completely eliminated or if you are re-exposed to HPV. Sometimes what looks like recurrence is actually a new verruca developing nearby. Ensuring complete treatment and reducing exposure in high-risk environments helps prevent recurrence.
When should you see a podiatrist in Dublin?
Book an appointment if your verruca has been present for more than a year without shrinking, if it is spreading to form a cluster, or if it causes pain when you walk. Any lesion that bleeds easily, changes colour, or does not look like a typical verruca should be assessed promptly to rule out other conditions.
If you have tried over-the-counter treatments for several months without success, professional treatment is likely needed. Patients we see from Stillorgan and the surrounding area often tell us they wish they had come sooner rather than persisting with ineffective home remedies.
Our clinics in Mount Merrion and Finglas offer convenient online booking, and we can usually see you within a few days.
CONCLUSION: Verrucas do not always need treatment, but when they cause pain or refuse to clear on their own, professional help makes a real difference. At Foot Focus Podiatry, one of Dublin’s largest podiatry providers, we assess each case individually and recommend the most effective approach for your situation.
