Plantar Warts
Plantar warts grow on the sole of the foot, pushed flat by body weight until they resemble a callus with tiny dark dots (clotted blood vessels). They're caused by HPV entering through small cuts or breaks in the skin — often picked up at pools, locker rooms, or shared showers.
Symptoms
- A hard, thickened patch of skin on the sole of the foot
- Tiny black or dark-brown dots visible within the lesion (clotted blood vessels)
- Pain when standing or walking, as if there's a pebble in the shoe
- Multiple small warts clustered together (mosaic warts)
- Pain when pinching the lesion from the sides (rather than pressing directly on it)
Who Gets It
Anyone who walks barefoot on shared surfaces — pools, gym locker rooms, yoga studios, communal showers — can pick up the HPV strain that causes plantar warts. Children and teenagers are especially susceptible, as are people with weakened immune systems. The virus enters through small breaks in the skin, often invisible to the naked eye.
Austin's active community uses shared facilities constantly — trail running groups, cycling studios, community pools. Kids playing barefoot at Barton Springs or Brushy Creek are exposed. Plantar warts are extremely common here, and most patients wait too long with OTC treatments that aren't working.
Treatment
In-office treatment options include:
- Cryotherapy — controlled freezing that destroys the wart tissue
- Chemical treatment — prescription-strength acids, stronger than OTC products
- Surgical excision for resistant warts that haven't responded to other methods
Most plantar warts resolve in one or two office visits. Dr. Wokasien will recommend the approach that fits the wart's size, location, and your pain tolerance.
When to Call
Call (512) 250-0444 if the wart has persisted despite weeks of home treatment, it's painful when walking, you have multiple warts or they're spreading, you're diabetic or have a compromised immune system, or you're not sure whether it's a wart or a callus.
Frequently Asked Questions
Can I treat a plantar wart at home?
OTC salicylic acid treatments work for some warts, particularly smaller, newer ones. Apply daily, keep the wart covered, and file away dead tissue weekly. If you haven't seen improvement after 4-6 weeks, it's time for professional treatment. Stubborn warts often need the higher concentrations only available by prescription.
Will a plantar wart go away on its own?
Eventually — immune response typically clears warts over 1-2 years. But walking on a painful wart for a year isn't necessary when treatment can resolve it in one or two visits. Waiting also allows them to spread to other areas or transmit to household members.
Does plantar wart treatment hurt?
Cryotherapy causes a cold, burning sensation during application and a throbbing feeling afterward that typically fades within a few hours. Chemical treatment is less immediately uncomfortable. Dr. Wokasien chooses the approach based on the wart's size and location. For children, he explains what to expect in terms they can handle.
How do I prevent plantar warts?
Wear sandals or water shoes in communal changing areas, showers, and pool decks. Keep feet clean and dry. Cover any cuts or breaks in the skin. Don't share shoes, socks, or towels. Inspect feet regularly if you frequent shared facilities.
How do I know if it's a wart or a callus?
Warts often hurt more when you pinch them from the sides; calluses hurt when you press directly on them. Warts typically show tiny dark dots (blood vessels) when you look closely; calluses don't. The skin lines on the sole also interrupt at a wart but continue through a callus. When in doubt, Dr. Wokasien can tell you definitively.
Can plantar warts spread to other parts of my body?
The HPV strains causing plantar warts typically don't spread beyond the feet. They can, however, spread to other areas of the sole or to other people through shared surfaces. Treating the wart promptly limits spread.
My child has a plantar wart. Should I bring them in?
If OTC treatment hasn't worked after a few weeks, yes. Children's warts respond well to professional treatment, and Dr. Wokasien has 47 years of experience working with kids. Saturday morning appointments are available if weekday scheduling is difficult.
