What is a Plantar Wart?
A plantar wart is a hard, grainy growth that usually appears on bottom of the foot, in areas where the most pressure is absorbed. Plantar warts occur when the human papillomavirus (HPV) makes contact with the skin on the soles of feet. The virus is usually introduced into the body through small cuts or openings on the bottom of the foot.
Types of Plantar Warts
Because they are spread through viral infections, those with weakened immune systems—such as children and senior citizens—are more likely to develop these warts. While most warts are visible, some plantar warts grow inwards—due to too much pressure—and form a callus. The two most common types of plantar warts include:
- Solitary wart: When there is just one single wart that increases in size and may develop into additional “satellite” warts.
- Mosaic wart: In some cases, multiple warts cluster together in one area—these warts are usually more difficult to treat.
Symptoms of Plantar Warts
While most cases of plantar warts can go away on their own with time, most people want faster relief. The goal of podiatric treatment for plantar warts is to completely remove the wart, not cover it up. Common warning signs of plantar warts include:
- Small, fleshy and rough growths develop
- Hard, thickened skin forms
- Formation of small clotted blood vessels
- Pain when walking or standing
- Tenderness in the affected area
Your doctor can usually diagnose a plantar wart by completing a simple physical exam. He or she may remove a section of the lesion to send out for further testing.
Treating Plantar Warts
If walking becomes painful or the warts are spreading, there are over-the-counter treatments available—though these often require multiple treatments and are still ineffective. When self-care and home remedies fail, visit your podiatrist. Your doctor may recommend these conservative, non-invasive treatments:
- Prescription-strength wart medications
- Cryotherapy (freezing off the wart)
- Immune therapy
- Minor surgery to cut away the wart
- Laser treatment
