Plantar Warts (Verrucae)

A plantar wart, also known as a verruca pedis or simply a verruca, is a small growth that develops on the sole of the foot. Verrucas are caused by certain strains of the human papillomavirus (HPV), which can enter the skin through tiny cuts or areas of damage. They are common and generally harmless, although they can sometimes become uncomfortable or painful.

Verrucas may appear as small, rough or flattened areas of skin, sometimes with tiny dark dots within them. Because they develop on weight-bearing areas such as the heel or ball of the foot, pressure can cause them to grow inwards beneath a layer of hard skin. This may make walking or standing uncomfortable. Several verrucas can also appear together in a cluster, known as a mosaic wart.

The virus can spread through direct contact or from contaminated surfaces, particularly in warm, damp communal areas such as swimming pools and changing rooms. Wearing flip-flops or pool shoes, avoiding sharing towels, socks or footwear, and covering the verruca when swimming can help reduce the chance of spreading it. Try not to scratch, pick or cut the area, as this may irritate the skin and spread the virus further.

Some verrucas disappear naturally without treatment. However, treatment may be helpful if the verruca is painful, persistent, spreading or interfering with your normal activities. A podiatrist can assess the area to confirm whether it is a verruca and discuss the treatment options most appropriate for you.

Treatments are available and may include professional reduction of the overlying hard skin, topical preparations or cryotherapy. Cryotherapy involves carefully freezing the verruca, usually with liquid nitrogen, to target the affected tissue. More than one treatment session may sometimes be required, and your podiatrist will explain the procedure and what you can expect.

If you think you may have a verruca, or if a growth on your foot is painful, changing in appearance or repeatedly returning, please get in touch to arrange an assessment. Professional advice can provide reassurance, ensure the correct diagnosis and help you choose a treatment suited to your needs. People with diabetes, poor circulation or a weakened immune system should most definitely seek professional guidance before attempting any treatment themselves.
