Plantar warts cause a patch of thicker skin on the bottom of your foot. They can be painful when you stand, and may be small or may spread to a larger part of your foot. Most warts go away on their own, but you can also treat them.
Once your doctor has confirmed that you have a plantar wart and not another skin issue, you may be able to use over-the-counter treatments for the warts. For those treatment you will apply a medicine to the wart on a regular schedule. If you have other foot conditions, are diabetic, or have an infection, talk to your doctor about your treatment options.
To help keep the warts away, always wear flipflops in public pools and locker rooms, dry your feet thoroughly with a clean towel, and don't wear sweaty socks.
