These noncancerous growths or bumps, caused by the human papillomavirus, come in a variety of shapes and sizes. The virus enters through cuts or breaks in the skin and manifests beneath pressure points on your feet, such as the balls of the feet or the heels. Pressure from standing and walking push these warts beneath the skin’s surface where friction causes a rough patch of thickened skin to develop over the top.
Plantar warts are not a serious health concern but they may become painful. As the overgrown callus becomes larger, placing weight on the affected area can be painful. This condition is an aggravating inconvenience that you don’t need to endure. Self treatments may take months or years to give you relief.
