sudden wart

Overview

A wart is a small, rough growth on the skin. A sudden wart is one that appears quickly, usually after contact with a common virus called human papillomavirus (HPV). Most are harmless.

Very common. At any given time, millions of people have warts, with children and teens affected most often.

Anyone can get a sudden wart, but they are more common in children and people with weakened immune systems.

Symptoms

Common symptoms

• A small, firm bump on the skin.
• The surface may be rough, smooth, flat, or raised.
• Skin-colored, pink, or brown. Sometimes with tiny black dots.
• Usually painless, but might hurt if on a pressure area like the sole of the foot.

Symptoms in children

• Warts often appear on hands, elbows, knees, and the face.
• They may come in clusters, but are usually harmless.

Symptoms in older adults

• Warts can last longer and may be harder to treat.
• Changes in number or appearance should be checked, as skin cancer can sometimes mimic a wart.

Causes

Main causes

• Infection with human papillomavirus (HPV).
• The virus enters the skin through tiny cuts or scrapes.
• Direct skin-to-skin contact with another person's wart.
• Contact with surfaces like locker room floors or shared towels.

Risk factors

• Childhood or teenage years.
• Biting nails or picking at hangnails.
• Having a weakened immune system, such as from certain illnesses or medicines.
• Walking barefoot in public showers or pools.

When to see a doctor

See a doctor urgently if:

• If a wart becomes swollen, red, or begins to drain fluid, you may have an infection and should be seen the same day.

Book a routine appointment if:

• If the wart does not go away after a few months, spreads, causes pain, or returns after treatment.

Diagnosis

A doctor can usually tell if a growth is a wart just by looking at it. They may use a small handheld magnifying glass called a dermatoscope to see the details more clearly.

Tests that may be done

• Usually no tests are needed.
• In rare cases, a doctor may take a small sample (biopsy) to confirm the diagnosis.

What to expect at your appointment

A simple, painless exam. The doctor will ask how long it has been there and whether you have had warts before.

Treatment

Many warts disappear without any treatment, but you can also try self-care methods. If they are painful, spreading, or bothersome, your doctor can discuss medical options.

Self-care at home

• Wash the area gently with soap and water.
• File the wart lightly with a disposable emery board, but keep it separate from your other toiletries.
• Cover the wart with a waterproof plaster or tape to help it peel away while protecting nearby skin.
• Do not pick, scratch, or cut the wart yourself — that can spread the virus.

Medical treatments

For warts that do not go away, doctors may use cryotherapy (freezing), prescription topical treatments, laser therapy, or immunotherapy. These are done in a clinic or at home with a doctor's guidance. The right choice depends on the wart's location, size, and your overall health.

When is surgery considered?

If other treatments have not worked or the wart is very large, a specialist might remove it with a minor procedure. This is not often needed.

Living with this condition

Keep the wart dry and clean. Wash your hands after touching it. Use your own towel and avoid sharing personal items.

Lifestyle tips

• Do not bite your nails or pick at the wart.
• Wear flip-flops or water shoes in communal showers and pool areas.
• Moisturize the skin to prevent cracks where the virus can enter.

Diet and exercise

A healthy diet and regular exercise help keep your immune system strong, which can help your body fight off the virus. No specific food will cure a wart.

Mental health and emotional wellbeing

Warts can feel embarrassing, especially for children. Remind yourself (or your child) that they are common, not dirty, and usually temporary.

Prevention

You cannot always prevent warts, but you can lower the risk by avoiding skin contact with warts, keeping your skin intact and moisturized, and not walking barefoot in public places.

Vaccines

The HPV vaccine protects against some types of HPV that cause genital warts and cancers, but it does not protect against the strains that cause most common warts on the hands and feet. Still, it is recommended and worth asking your doctor about.

Screening programmes

There is no routine screening for common warts. If you notice any new or changing skin bumps, a doctor can check them.

Complications

If left untreated

• The wart may stay the same, slowly grow, or spread to other parts of the body.
• Warts on the soles of the feet (plantar warts) can become painful when walking.
• Very rarely, a harmless-looking bump can actually be a different kind of skin growth, so getting a diagnosis is wise.

Long-term outlook

With time and patience, most warts fade away or respond well to treatment. Your immune system is your best ally, and there are plenty of safe options to help you feel comfortable in your skin again.
