Overview

Warts and verrucas are caused by human papillomavirus infecting the top layer of skin. A verruca is simply a wart on the sole of the foot — the same thing, pressed inwards by your body weight, which is why it hurts.

They are harmless. They also go away on their own — around two-thirds clear within two years in children, though it can take longer in adults. That is genuinely a legitimate option, and worth weighing before starting months of treatment.

Two safety points that matter more than anything else here:

  • Never use over-the-counter wart treatments on the face or the genital area. They are far too harsh for that skin and cause chemical burns. Genital warts need entirely different treatment
  • If you have diabetes, poor circulation or reduced sensation in your feet, do not use salicylic acid or freezing treatments on a verruca. The skin damage they cause is a genuine route to an ulcer or infection. Get it looked at instead

And one myth worth clearing up: the little black dots are not seeds or roots. They are tiny clotted blood vessels. Warts have no roots, and nothing needs digging out.

Common symptoms

Common warts

  • Firm, raised lumps with a rough, cauliflower-like surface
  • Usually on hands, fingers, around nails, or on knees
  • Skin-coloured or slightly darker
  • Tiny black dots within them — clotted capillaries, not seeds
  • Usually painless, unless knocked or beside a nail

Verrucas

  • On the sole of the foot, flattened by body weight and growing inwards
  • Often with a rough surface surrounded by hard skin
  • Painful on standing or walking — characteristically like a small stone in the shoe
  • Sometimes in clusters

Other types

  • Plane warts — small, flat, smooth, often numerous, and commonly on the face or backs of the hands in children. Do not use shop-bought treatments on facial warts
  • Filiform warts — thread-like, typically around the eyes, nose or mouth

How to tell a verruca from a corn or callus

A genuinely useful distinction, since they are treated differently:

  • A verruca interrupts the skin lines — the normal fingerprint-like ridges of the sole run around it rather than through it. A corn or callus keeps them running straight over
  • A verruca hurts when pinched from the sides. A corn hurts when pressed straight down
  • Verrucas often have the black dots; corns have a hard central core

What needs assessment rather than treatment

  • Any lesion that bleeds, ulcerates, changes colour, or grows rapidly
  • A "verruca" that has not responded to months of correct treatment — some skin cancers on the foot are mistaken for verrucas for a long time
  • Widespread or numerous warts in an adult, which raises immune status
  • Anything on the genitals — see genital warts
  • Warts in anyone immunosuppressed

Causes and risk factors

The virus

Human papillomavirus — low-risk types, which do not cause cancer. Warts on the hands and feet come from different types than those affecting the genital area, and hand warts do not become genital warts.

How they spread

  • Direct skin contact
  • Damp communal floors — swimming pools, changing rooms, gym showers. The virus survives well in moisture, and softened skin lets it in
  • Shared towels, shoes and socks
  • Scratching, picking or biting, which spreads them along the same person's skin — which is why they appear in rows
  • Shaving over an affected area
  • Sharing nail files and clippers

What makes them more likely

  • Children and teenagers, in whom they are extremely common
  • Broken or macerated skin, and swimming
  • Nail biting and finger picking
  • Immunosuppression — where warts can be numerous, large and persistent
  • Handling raw meat and fish occupationally

What they are not

  • Not a hygiene problem
  • Not caused by touching frogs or toads
  • Not rooted. Warts sit in the top layer of skin. The black dots are clotted blood vessels, and there is nothing beneath to remove
  • Not dangerous, and not pre-cancerous

How it is diagnosed

Diagnosed by appearance, and a clear close-up photograph is usually enough — which suits a remote consultation well.

What we assess

  • Appearance, number and site
  • How long, and whether they are spreading
  • Whether they hurt, and whether they affect walking or work
  • What you have tried, for how long, and how consistently — which is nearly always the reason treatment has "failed"
  • Diabetes, circulation and sensation in the feet — asked in every case involving a verruca, because it changes what is safe
  • Immunosuppression or medication affecting the immune system

The distinction that matters on the foot

Verruca or corn: look at whether the skin lines run through it or around it, and whether it hurts more when pinched sideways or pressed down. Getting this wrong means months of the wrong treatment.

What needs to be seen in person

  • Any lesion that bleeds, ulcerates, changes colour or grows
  • A "verruca" not responding after several months of correct treatment — which needs examining rather than another round of freezing, because skin cancers on the sole are genuinely mistaken for verrucas
  • Facial warts, where scarring risk means treatment should be specialist
  • Numerous or very large warts in an adult
  • Any foot lesion in someone with diabetes or poor circulation

How we treat it online

1. Doing nothing — a real option

Around two-thirds clear on their own within two years in children. If they are painless and not bothering anyone, waiting is entirely reasonable and avoids months of effort. Treatment is worth it where they hurt, spread, catch on things, or genuinely bother you.

2. Salicylic acid — the mainstay

Available over the counter, and the treatment with the best evidence. What decides whether it works is technique and persistence:

  • Soak the area in warm water for five to ten minutes first
  • File the surface down with an emery board or pumice — kept only for that purpose and never used elsewhere
  • Apply the acid to the wart alone, protecting the surrounding skin with petroleum jelly
  • Cover it
  • Repeat daily, for at least twelve weeks

Almost everyone who says it did not work stopped at three or four weeks, or skipped the filing. That combination is the treatment; the acid alone is not.

3. Cryotherapy

Freezing, usually every two to three weeks over several sessions. Comparable results to properly used salicylic acid rather than dramatically better — and often used alongside it. It stings, and it can blister.

4. Duct tape

Genuinely studied, with modest and mixed evidence. Harmless, cheap, and reasonable to try alongside filing and acid, particularly in children who dislike the acid stinging.

5. Where we refer

Dermatology or podiatry for resistant, painful or extensive warts, facial warts, or anyone immunosuppressed. Other treatments — including stronger acids, curettage and immune-based treatments — are available there.

6. What we will not do

  • Recommend over-the-counter treatments for the face or genital area
  • Recommend salicylic acid or freezing for a foot lesion in someone with diabetes or poor circulation
  • Keep treating a lesion that has not responded over months instead of arranging examination
  • Suggest cutting, burning or digging anything out at home

Important

When to seek urgent help

Warts and verrucas are not an emergency. Seek prompt medical attention for:

  • Spreading redness, warmth, swelling or pus around a treated area, particularly with fever — infection following treatment
  • Any foot wound, blister or ulcer in someone with diabetes or poor circulation
  • Severe pain or blistering after treatment
  • Bleeding that will not stop

Book an appointment for:

  • Any lesion that bleeds, ulcerates, changes colour, or grows rapidly
  • A verruca that has not responded to several months of correct treatment — which needs examining, because skin cancers on the foot are genuinely mistaken for verrucas
  • Painful verrucas affecting walking, work or sport
  • Warts on the face, where treatment should be specialist
  • Numerous, large or persistent warts in an adult — which raises the question of immune status
  • Warts in anyone immunosuppressed or on chemotherapy
  • Uncertainty about whether it is a verruca or a corn
  • Anything on the genital area, which needs different treatment entirely

Prevention and self-care

If you have diabetes or circulation problems

Do not treat a verruca yourself. Salicylic acid and freezing both damage surrounding skin deliberately, and in a foot with reduced sensation or blood supply that is a genuine route to an ulcer. See a podiatrist or a doctor instead. This is the most important line on this page for anyone it applies to.

Making treatment work

  • Soak, file, apply, cover — daily, for twelve weeks. All four parts, consistently
  • Keep a dedicated file or pumice and never use it on healthy skin
  • Protect surrounding skin with petroleum jelly
  • Do not apply to broken or inflamed skin
  • Be patient. This is slow by nature, and stopping early is the main reason it fails

Stopping them spreading

  • Do not pick, scratch or bite them — the main way they multiply, and why they appear in lines
  • Cover a verruca with a plaster or verruca sock for swimming
  • Wear flip-flops in communal showers and changing rooms
  • Do not share towels, socks, shoes, files or nail clippers
  • Keep feet dry; change socks daily
  • Do not shave over an affected area
  • Wash hands after touching them or applying treatment

School, swimming and sport

There is no exclusion from school, swimming or sport for warts or verrucas. Children should not be kept out of the pool. Cover a verruca and carry on — the virus is far too common to be worth restricting anyone over.

What is not worth it

  • Cutting, burning or digging at them — there is nothing underneath to remove, and you risk infection and scarring
  • Home freezing kits used on the face
  • Banana skin, garlic, apple cider vinegar and similar — harmless, unevidenced, and vinegar in particular burns children's skin
  • Expensive laser treatment marketed for verrucas, where the evidence is poor

A note on perspective

Warts are harmless, extremely common, and say nothing about hygiene or health. For most children the sensible approach is to file them, cover them for swimming, and let time do the work.

NHS or private

Most warts and verrucas disappear on their own without any treatment — around two-thirds within two years in children, more slowly in adults. Doing nothing is a legitimate and often sensible choice, and it costs nothing.

Salicylic acid preparations and home freezing kits are available over the counter for a few pounds, and salicylic acid is the treatment with the best evidence. It requires persistence — daily application for up to twelve weeks, with the dead skin filed down between applications — and the commonest reason it fails is stopping after a fortnight.

The NHS generally does not treat warts and verrucas, regarding them as self-limiting and cosmetic. That is not rationing so much as an accurate reading of the evidence.

Where money is genuinely wasted: repeated private cryotherapy, which has similar outcomes to salicylic acid at considerably greater cost and discomfort; and the various duct tape, homeopathic and “wart removal” products with no reliable evidence.

Where a consultation is worth it: if the diagnosis is uncertain — a lesion assumed to be a wart that is growing, bleeding, changing or painful needs a proper look, since some skin cancers are mistaken for warts; if you have diabetes or poor circulation, where foot lesions need care; or if you are immunosuppressed, where warts can be extensive and persistent.

Evidence and guidelines

NICE Clinical Knowledge Summary, Warts and verrucae, is the principal reference. It notes that most resolve spontaneously without treatment and that treatment is not necessary unless lesions are painful, unsightly, persistent or causing distress.

CKS recommends topical salicylic acid as first-line, applied daily with regular paring, and notes that treatment may need to continue for up to twelve weeks.

CKS notes cryotherapy is no more effective than salicylic acid for most lesions, is more painful, and requires repeated treatments — the basis for the cost point above.

CKS advises particular caution in people with diabetes or peripheral vascular disease, where salicylic acid and cryotherapy carry a risk of ulceration.

CKS sets out referral criteria — diagnostic uncertainty, immunosuppression, extensive or facial lesions, and any lesion with atypical features. NICE NG12 underpins the advice on a lesion that is growing, bleeding or changing.

Common questions

Do I need to treat them at all?

Not necessarily. Around two-thirds clear by themselves within two years in children, and treatment takes months of daily effort. If they are painless and not bothering anyone, waiting is a perfectly sensible choice. Treat them if they hurt, spread, catch on things, or you simply want them gone.

Why hasn't the treatment worked?

Almost always because it was stopped too early or the filing was skipped. The method is: soak, file, apply, cover — every day, for at least twelve weeks. Most people stop at three or four weeks, or apply the acid to an unfiled surface it cannot penetrate. Persistence is the treatment.

What are the little black dots — are those the roots?

No. Warts have no roots. The black dots are tiny clotted blood vessels within the wart, which sits entirely in the top layer of skin. There is nothing beneath to dig out, and trying to do so causes infection and scarring rather than a cure.

Is it a verruca or a corn?

Two useful checks. A verruca interrupts the skin lines — the ridges of the sole run around it rather than through it — while a corn keeps them running straight over. And a verruca hurts when pinched from the sides; a corn hurts when pressed down. Getting this right saves months of the wrong treatment.

Can my child still swim?

Yes. There is no exclusion from swimming, school or sport. Cover a verruca with a plaster or a verruca sock and carry on. Keeping a child out of the pool for this is unnecessary and unfair to them.

I have diabetes — can I use the treatment from the chemist?

No, please do not. Salicylic acid and freezing work by deliberately damaging skin, and on a foot with reduced sensation or blood supply that is a genuine route to an ulcer and infection. Get it looked at by a podiatrist or doctor instead — this is one of the clearest do-not-self-treat situations in this whole area.

Could hand warts turn into genital warts?

No. Different HPV types cause each, and warts on the hands do not become genital warts. Both are caused by low-risk types that do not cause cancer.

It looks like a verruca but it is not getting better after months.

Get it examined. A lesion on the sole that has not responded to correct treatment over several months needs looking at properly, because some skin cancers on the foot are mistaken for verrucas and treated for a long time before anyone questions the diagnosis. It is usually nothing — but it is worth confirming rather than repeating the freezing.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
