What are plantar warts?

A plantar wart is a lesion on the sole of the foot that can cause pain, especial when they are found on the ball of the foot or the heel. Warts are caused by a virus, human papilloma virus (HPV), and appear as a soft central core that is surrounded by thick hardened skin resembling a callus. Multiple tiny black spots can sometimes be seen on the wart as this is the wart’s blood supply.

Around 50% of warts will disappear without treatment, while some warts remain for years. If your warts are causing you pain or discomfort, please see a foot specialist to receive the appropriate treatment to relieve your symptoms.

How can you treat a wart?

  • Over-the-counter wart pads – contain small traces of salicylic acid to remove the wart.
  • Topical acids – stronger concentrations of salicylic acid or use of cantharidin to produce a blister to help remove the wart.
  • Freezing (cryotherapy) – kills the wart but may be too painful for children to tolerate.
  • Laser therapy – uses light to destroy the blood vessels that supplys the wart, hence killing the wart.
  • Microwave treatment (SWIFT) - creates an immune response forcing your own body to fight and destroy the wart virus
  • Surgical excision – requires numbing the area and physically removing the wart and applying a chemical to the area to help reduce chance of reg.

Ways to lower chances of getting plantar warts:

  • Wear flip flops or water shoes in public places such as pools, water parks or locker rooms.
  • Wear a clean pair of socks everyday.
  • If you live with someone who has plantar warts, make sure they always wear something on their feet as it is contagious.
  • Do not share socks or shoes with someone who has a plantar wart, it is contagious.

Warts are notoriously stubborn and tough to get rid of. Even when the wart appears to be gone, the virus remains in the skin and the wart grows again. Please see a foot specialist who can help develop a proper treatment plan for you wart complaint.
