What are the best ways to treat plantar warts?

Ask the doctor

Q. I have recently developed plantar warts. I looked at over-the-counter medications, but are they the best treatments for this?

A. Plantar warts are hard, grainy growths that often appear on the heels or balls of your feet. They are caused by the human papillomavirus that enters your body through tiny cuts or breaks on the bottom of your feet. Plantar warts usually aren't a serious health concern and most resolve spontaneously. However, in some people the warts can persist for months and require treatment.
