wart flare ups

Overview

Wart flare-ups happen when one or more warts reappear or spread on your skin. Warts are small, firm growths caused by certain types of the human papillomavirus (HPV). This virus enters through tiny breaks in the skin and makes skin cells grow quickly, forming a wart.

Yes. Warts are very common, especially in school-age children and teens. Most people will get at least one at some point.

Anyone can get warts, but children, people with weakened immune systems, and those who frequently use shared showers or gyms have a higher chance.

Symptoms

Common symptoms

• A small, rough bump on the skin that may feel like cauliflower
• Skin-colored, pink, or slightly brown, depending on your skin tone
• Tiny black dots (these are small blood vessels, not wart 'seeds')
• On the hands, feet, face, or around nails

Symptoms in children

• Warts can appear in clusters or as a single bump
• They are more likely to appear on hands, knees, and faces
• Children may feel self-conscious or embarrassed by visible warts

Symptoms in older adults

• Warts may be less common but can appear if the immune system is weaker
• Older skin may have growths that look like warts but need checking
• Warts on feet may become more painful with age-related foot problems

Causes

Main causes

• Infection with certain types of the human papillomavirus (HPV)
• Direct skin-to-skin contact with a wart or with something that touched a wart
• The virus entering through cuts, scrapes, or other breaks in the skin

Risk factors

• Being a child or teenager
• Having a weakened immune system (for example, from illness or certain medicines)
• Biting your nails or picking at cuticles
• Walking barefoot in public showers, locker rooms, or pools
• Sharing towels, razors, or nail clippers with someone who has warts

When to see a doctor

See a doctor urgently if:

• Warts that are painful, bleeding, or growing quickly
• Warts that change color or look unusual
• You have diabetes, kidney disease, or a weakened immune system
• You suspect the growth may not be a wart

Book a routine appointment if:

• Warts that do not go away after a few months
• Warts that spread or appear in large numbers
• You are bothered by how a wart looks
• Warts on your face, genitals, or near your nails

Diagnosis

A doctor or nurse can usually diagnose a wart by looking at it. Sometimes they use a small handheld magnifying tool called a dermatoscope to see it more clearly.

Tests that may be done

• Visual examination of the skin
• Dermatoscopy (skin magnification) to look at the surface pattern
• Rarely, a skin biopsy (taking a tiny sample) if the growth is unusual

What to expect at your appointment

Checking a wart is quick and usually painless. If your doctor needs to take a sample, they will numb the area first. You can ask questions during the examination.

Treatment

Treatment for warts aims to remove them and help your immune system fight the virus. Because warts can be stubborn, a combination of home care and professional treatment may work best. Not every wart needs treatment.

Self-care at home

• Keep the wart clean and dry
• Cover it with a plaster or bandage to help prevent spreading
• Avoid picking, scratching, or biting the wart
• Wash your hands after touching the wart
• Do not share towels, shoes, or personal items

Medical treatments

A healthcare professional may offer treatments such as freezing (cryotherapy), laser therapy, or a minor procedure to remove the wart. They can also recommend safe, prescription-strength skin treatments that you apply at home. Always follow their advice, and never use surgical instruments on yourself.

When is surgery considered?

Surgery is only occasionally needed for very large or deeply rooted warts. It is usually done under local anesthetic, so you stay awake but feel no pain.

Living with this condition

Treat warts patiently — flare-ups can take weeks or months to resolve. Keep the area protected and avoid activities that might cause the virus to spread to other parts of your body.

Lifestyle tips

• Wear flip-flops or shower shoes in public pools and changing rooms
• Use a separate towel for the area around the wart
• If you have a wart on your hand, avoid nail-biting and cuticle picking
• Change socks and shoes daily if you have a foot wart

Diet and exercise

Eating a balanced diet with plenty of fruits and vegetables supports your immune system, which can help your body clear the virus. Regular exercise is fine and does not make warts worse.

Mental health and emotional wellbeing

Visible warts can feel embarrassing, but they are very common and not a sign of poor hygiene. It is normal to feel self-conscious. Talking to a trusted friend, family member, or a counselor may help.

Prevention

You can lower your risk by avoiding direct contact with warts, keeping your skin intact, not walking barefoot in shared wet areas, and not sharing personal items. The wart virus is easily spread, but these habits help.

Vaccines

A vaccine for HPV exists, but it protects against certain high-risk HPV types, not all the types that cause common warts. Ask your healthcare provider whether HPV vaccination is recommended for you or your child.

Screening programmes

There is no routine screening for common warts. However, if you have any skin growth that changes or doesn't heal, see a healthcare professional for evaluation.

Complications

If left untreated

• Warts may spread to other areas of your body or to other people
• They may become more numerous or uncomfortable
• In people with weakened immune systems, warts can be harder to treat

Long-term outlook

Most warts are harmless and resolve on their own within months to a few years. With treatment, they often clear faster. Even if they return, there are many safe and effective options available. You do not have to accept being uncomfortable or self-conscious.
