What is a Plantar Wart?
A plantar wart is a small growth that develops on the bottom of the foot when the skin is infected by a virus. There are two kinds of plantar warts: solitary (single) or mosaic, in which several smaller warts grow in a cluster at one area.

Signs and Symptom

• Thickened skin resembling a callus
• Pain while walking, standing, or when the sides of the wart are squeezed
• Tiny black dots on the surface of the wart. These are dried blood contained in the tiny blood vessels called capillaries

What Causes a Plantar Wart?
Plantar warts are caused by direct contact with the human papilloma virus (HPV), usually by going barefoot in public places like locker rooms or swimming pools.

Diagnosis
Diagnosing a plantar wart is relatively simple. The podiatrist will examine the patient's foot and look for any signs or symptoms. It should be noted, though, that although diagnosis is simple, treatment may not be, and a patient should never attempt to remove a wart themselves, is it may cause more harm than good.
