Overview

Warts on the feet, often referred to as plantar warts, are small, benign growths on the skin caused by the human papillomavirus (HPV). They typically develop on the soles of the feet and can appear as rough, grainy growths or thickened patches of skin. Here’s a detailed breakdown of what plantar warts are, why they occur, their common causes, and the best treatment options recommended by podiatrists.

What are Plantar Warts?

Appearance

Plantar warts are usually flat and hardened, often resembling calluses, and they can have a pinched or dotted appearance due to the blood vessels inside.

Location

They typically form on weight-bearing areas, such as the heels or the balls of the feet, which may cause discomfort, especially during standing or walking.

Why do Plantar Warts Occur?

Plantar warts occur due to infection by certain strains of the human papillomavirus (HPV). The virus enters the skin through tiny cuts, abrasions, or breaks in the epidermis. While most people are exposed to HPV at some point in their lives, not everyone develops warts. Factors influencing the occurrence of warts include:

Skin Condition

Compromised skin barriers, such as calluses or cuts, can make it easier for the virus to enter.

Moist Environments

Warts are more likely to develop in moist environments, such as public swimming pools, showers, and locker rooms, where the virus can thrive.

Immune Response

Individuals with compromised immune systems may be more susceptible to developing warts.

Common Causes of Plantar Warts

Direct Contact

Walking barefoot in areas where the virus is present, such as public pools or communal showers, increases the risk of transmission.

Skin-to-Skin Contact

While less common, direct contact with an infected person can lead to the virus spreading.

Weakened Immune System

Those with weakened immune systems or skin conditions may be more prone.

Treatment Options

Our Podiatrists at Sydney Podiatry have several effective treatment options for plantar warts, which may include:

Salicylic Acid

Often in the form of pads or solutions, salicylic acid works to gradually exfoliate and soften the wart so it can be removed.

Cryotherapy

This involves freezing the wart using liquid nitrogen, causing it to blister and eventually fall off. This method often requires multiple treatments.

Electrosurgery

This technique uses an electric current to remove the wart and is generally reserved for larger or stubborn warts.

Laser Therapy

Podiatrists may use laser treatment for warts that do not respond to other treatments, targeting the blood vessels within the wart.

Cantharidin

A blistering agent applied by a podiatrist that causes the wart to blister and eventually be removed.

Immunotherapy

In cases where warts are resistant to other treatments, immunotherapy using topical agents that stimulate the immune system can be considered.

Surgical Removal

For persistent warts that do not respond to other treatments, minor surgical removal may be necessary.

Preventive Measures

Avoid Walking Barefoot

Especially in communal areas such as pools or locker rooms.

Personal Hygiene

Keeping feet dry and clean, and changing socks regularly can help.

Buy Proper Footwear

Wearing shoes that fit well and provide proper support can prevent skin damage that allows the virus to enter.

If you suspect you have plantar warts, it’s important to consult one of our Podiatrist at Sydney Podiatry for an accurate diagnosis and appropriate treatment tailored to your needs.
