What is a plantar wart?

Warts are small, rough, thick and often painful lumps on the skin that are caused by a virus called the Human Papilloma Virus (HPV). When a wart is present on the bottom of your foot, it’s called a plantar wart.
Causes
Common warts are caused by the human papillomavirus (HPV). Most forms, however, are spread by:
- casual skin contact
- through shared objects, such as towels or washcloths
- The HPV virus thrives in warm, moist environments. Consequently, you may contract the virus by walking barefoot around swimming pools or locker rooms.
Transmission
The virus usually spreads through breaks in your skin, such as a hangnail or a scrape Each person’s immune system responds to the HPV virus differently, so not everyone who comes in contact with HPV develops warts.
Symptoms
Plantar wart signs and symptoms include:
- A small, fleshy, rough, grainy growth (lesion) on the bottom of your foot, usually the base of the toes and forefoot or the heel
- Hard, thickened skin (callus) over a well-defined “spot” on the skin, where a wart has grown inward
- Black pinpoints, which are commonly called wart seeds but are actually small, clotted blood vessels
- Pain or tenderness when walking or standing

Treating plantar warts
- Using a mild acid in a safe and controlled environment, applied by an experienced Podiatrist. This usually requires multiple applications over several weeks and removes the viral cells slowly, allowing healthy skin cells to replace them.

- Cryotherapy to freeze warts using liquid nitrogen. W e often use this treatment together with other treatments to maximise the effects.
Plantar warts can resolve on their own, though the timing is highly unpredictable with some warts taking weeks and other being present for years. If your wart is causing you pain, discomfort, or is affecting the way you walk, we highly recommend having it treated.
