Plantar warts are skin viruses that usually appear on the bottom of feet or on toes. Other variations of warts may appear on top of feet as well. Plantar warts tend to be well defined flesh colored circular lesions. Most plantar warts are not serious but can be extremely painful to walk on and may spread and multiply if not treated in a timely fashion.
Causes of Plantar Warts
Plantar warts are caused by a skin virus called Huma Papilloma Virus (HPV). They can infect ones foot when the compromised skin comes into contact with moist surfaces like bathroom tiled floors and bathtub surfaces. After the skin has been infected it may take a while for a plantar wart to become visible. Due to walking pressure the wart continues to push inward and a layer of hard skin usually forms over it. There are also risk factors for the development of plantar warts, such as; use of communal showers, skin trauma and a weakened immune system.
Signs & Symptoms of Plantar Warts
Signs and symptoms for plantar warts include foot pain localized to a thickened or callused area of the sole. Warts may take on different forms. They can be rough or spongy, while others can appear thick and scaly. Plantar warts may appear as multiple cells with little dark spots which are tiny blood vessels that have clotted. They are often found over areas of pressure like the ball of the foot and the heel. Although rarer they can also appear on toes. They are similar to calluses but warts tend to be painful on pressure on either side of the lesion, while corns and calluses tend to be painful on direct pressure.
