They should each be treated differently. A wart is a small bump on the skin caused by a virus that infects the top layer of skin cells. This virus is contracted and lies dormant in the body. Periodically the virus will infect layers of the skin resulting in a wart. Removing the wart does not remove the virus from the body but it does remove the unsightly growth and can reduce the discomfort.
Common warts occur on the fingers, back of hands, arms, top of feet and other areas of the body.
They are usually free of pain. Common warts occur in people of all ages. Plantar warts occur on the bottom of the feet. They are spotted in appearance due to blood vessels that have become clotted within the wart. Plantar warts can be painful.
