That hard, rough patch on the sole of your foot with tiny black dots in the centre — you have probably been ignoring it for months. If you are based in Santry or the surrounding area, you are not alone. Verrucas are one of the most common foot complaints we see at our Dublin clinics, and the biggest question patients ask is simple: should I treat it or leave it alone? The answer depends on several factors including pain, location, and how long you have had it. This post explains what causes verrucas, when treatment makes sense, what options actually work, and when you can safely wait it out.
What causes verrucas?
Verrucas are caused by the human papillomavirus (HPV), which enters the skin through tiny cuts or abrasions on the sole of the foot. The virus thrives in warm, moist environments — swimming pools, gym changing rooms, and shared showers are common sources of infection.
Once the virus takes hold, it triggers rapid growth of skin cells in the outer layer of skin, creating the characteristic hard, raised lesion. The black dots you see are not roots — they are tiny blood vessels that have grown into the verruca.
Your immune system plays a major role in whether a verruca clears on its own or persists. Children and teenagers are more susceptible because their immune systems have not yet developed full resistance to HPV strains. Adults with weakened immune systems may also find verrucas harder to shift.
Walking barefoot in communal areas increases your risk significantly. Direct contact with contaminated surfaces allows the virus to enter through any small break in the skin. Sharing towels or footwear with someone who has a verruca can also spread the infection.
What are the symptoms of a verruca?
A verruca typically appears as a small, rough growth on the sole of the foot. It often has a cauliflower-like texture with a harder outer ring of skin. The tiny black dots in the centre are clotted blood vessels — a reliable sign you are dealing with a verruca rather than a corn.
Pain is the main symptom that brings patients to our Dublin clinics. Verrucas on weight-bearing areas like the heel or ball of the foot can feel like walking on a small stone. Squeezing the sides of the verruca often causes sharp pain, which helps distinguish it from a callus.
Some verrucas cause no discomfort at all. But if yours is painful, growing, spreading to other areas, or has been present for more than two years, it is time to stop waiting and book an assessment.
How are verrucas treated at Foot Focus Podiatry?
Treatment decisions depend on how much the verruca affects your daily life. At Foot Focus, our CORU-registered podiatrists assess each case individually to determine whether active treatment is needed or whether monitoring makes more sense.
For verrucas that need treatment, we use several evidence-based approaches. Salicylic acid treatment involves carefully applying a concentrated acid solution that breaks down the infected tissue layer by layer. This requires patience — multiple applications over several weeks are typical.
Cryotherapy uses liquid nitrogen to freeze the verruca, destroying the infected cells. This can be uncomfortable during treatment but is often effective for stubborn lesions.
For persistent or painful verrucas, we sometimes recommend needling — a procedure performed under local anaesthetic where the verruca is punctured repeatedly to trigger an immune response. This helps your body recognise and fight the virus.
Most patients see improvement within six to twelve weeks of starting treatment, though some stubborn verrucas take longer. We schedule follow-up appointments to monitor progress and adjust the approach if needed.

What patients in Santry are asking about verrucas
Q: Can I treat a verruca myself at home before seeing a podiatrist?
A: Over-the-counter treatments containing salicylic acid can work for mild verrucas. Apply after soaking the foot and file away dead skin between applications. If the verruca persists after eight weeks of consistent home treatment, professional assessment is worthwhile.
Q: How long does verruca treatment take to work?
A: Treatment typically takes six to twelve weeks depending on the size and depth of the verruca. Some clear faster while others need several months. Your podiatrist will monitor progress and adjust the treatment plan based on how the verruca responds.
Q: Should I cover my verruca when swimming?
A: Yes, covering your verruca with a waterproof plaster reduces the risk of spreading the virus to others. Wearing flip-flops in changing rooms and around the pool also helps protect you from picking up additional infections.
Q: Why does my verruca keep coming back after treatment?
A: Recurrence usually means the virus was not fully cleared or you have been re-exposed. Some people are more susceptible to HPV than others. A podiatrist can assess whether the original verruca persisted or if you have a new infection, then recommend a more targeted approach.
When should you see a podiatrist in Dublin?
Book a podiatry appointment if your verruca has been present for more than two years without improvement. Pain that affects how you walk or stand is another clear signal — you should not have to adjust your gait to avoid discomfort.
Seek professional assessment if the verruca is spreading to other parts of your foot or to family members. Changes in colour, bleeding, or rapid growth also warrant a closer look to rule out other conditions.
