Diseases and Conditions
Plantar warts are small growths that usually appear on the heels or other weight-bearing areas of your feet. This pressure may also cause plantar warts to grow inward beneath a hard, thick layer of skin (callus).
Plantar warts are caused by HPV. The virus enters your body through tiny cuts, breaks or other weak spots on the bottom of your feet.
Most plantar warts aren't a serious health concern and usually go away without treatment eventually. You may want to try self-care treatments or see your doctor to have the warts removed.
