Plantar warts (verrucae pedis) are caused by a virus. Warts are caused by the human papilloma virus (HPV). The virus enters the body through a break in the skin. This can easily occur when you are walking in bare feet in public bathing areas. The virus grows in warm moist environments like change rooms and pool areas. The virus is a common organism that we are all exposed to at some point in our lives.
Plantar means the bottom of the foot, but warts can occur anywhere on the foot. Plantar warts can be painful especially if they are on a weightbearing location of the foot. Sometimes they are mistaken for calluses because of layers of hard skin can build up on top of the wart. Warts have a clearly defined border. Warts appear spongy and bumpy. They may have tiny black spots in the centre. These are tiny blood vessel capillaries that supply blood to the wart. Most of the wart is below the surface of the skin. Often the wart is twice as big as the portion you see on your skin. Warts do not have roots.
The body's natural immune system can often destroy a wart without any treatment. Treatment options are varied. There are many drug store over the counter, acid plasters, gels or ointments which can destroy the wart.
You should seek professional help, if the wart becomes larger, becomes painful, spreads or does not respond to the over the counter wart remedies.
