What are Warts?
Warts are harmless outgrowths on the skin caused by human papillomavirus (HPV) infection. They grow on all body parts including face, fingers, feet, legs, hands, knees, inside your mouth, and the genital and rectal areas.
Plantar warts - appear on the bottom or soles of your feet, light brown bumps with tiny black dots on them.
Warts can spread from one person to another with skin contact. Warts may also be spread by using the towels or other personal items that have been used by a person with warts. Warts can bleed if picked or cut and can cause pain, especially plantar warts.
Diagnosis of Plantar Warts
Warts will be diagnosed by simple observation of the lesions. Your doctor may scrape the top layer of the wart and check for clotted blood vessels and at times a biopsy may be ordered.
Treatment for Plantar Warts
Warts disappear naturally but may take months or even years to disappear. Warts can be treated with different types of chemicals such as salicylic acid, liquid nitrogen to freeze warts, and also by laser treatment. Applying salicylic acid once or twice a day will help to destroy warts. If warts do not heal, then they may be removed surgically. Warts can recur even after treatment.
Other treatments include:
Cantharone, a medicine derived from the Japanese blister beetle, is applied with a Q-tip on warts. It causes a blister at each site and after some time the warts are destroyed. This treatment is very effective for most warts and is painless.
Bleomycin, an anti-cancer agent is also used. The pulsed dye laser is magnetized to the blood vessels which feed on warts, and carbon dioxide (CO2) lasers are also used for the removal of warts.
