Verruca

What are Verrucas?

Verrucas (also called plantar warts) are small, rough growths that appear on the soles of the feet. They are caused by a viral infection of the skin, specifically human papillomavirus (HPV).

They are contagious but usually harmless and often resolve over time.

Causes

• HPV infection – virus enters through small cuts or abrasions on the skin
• Walking barefoot in public areas – swimming pools, gyms, and communal showers
• Weakened immune system – increases susceptibility
• Skin trauma – minor injuries on the feet allow virus entry
• Moist environments – encourage virus survival and infection

Symptoms / Appearance

• Small, rough, or grainy bumps on the sole of the foot
• Hard, thickened skin (callus) over the verruca
• Tiny black dots (“seed warts”) inside the lesion – clotted blood vessels
• Pain or tenderness when standing or walking
• May appear alone or in clusters (mosaic warts)

Treatments

Professional Treatments

• Cryotherapy – freezing the verruca with liquid nitrogen
• Salicylic acid treatments – peel or gel to gradually remove the wart
• Laser therapy – targets blood vessels feeding the verruca
• Needling / surgical removal – for persistent or resistant warts
• Immunotherapy – stimulates the body to fight the virus in stubborn cases

Many verrucas clear naturally within months to a couple of years, but some persist without treatment.

Q3. Can I remove a verruca at home?
Mild cases can be treated with OTC salicylic acid, but persistent or painful warts should see a healthcare professional.

Q4. Can verrucas come back?

Children, teenagers, and people with a weakened immune system or frequent barefoot exposure in communal areas.
