What are they?
Warts are a commonly misunderstood condition affecting the feet. While typically non-contagious to others, they can spread within the same individual. Warts are essentially viral growths that are encapsulated or walled off. Plantar warts, which appear on the soles of the feet, often cause pain when pressure is applied. They usually develop after a puncture or injury to the skin, which allows the virus to enter and establish itself. Many people report acquiring warts after using public showers or swimming pools, where moist conditions can weaken the skin and increase susceptibility. Once a wart is established, it can spread to other parts of the foot. Whether we all carry dormant wart viruses or contract them through a specific injury remains unclear.
A key distinction must be made between plantar warts and certain calluses. Skin lines or striations pass through calluses but circumvent warts. Painful calluses, particularly on the ball of the foot, are often mistaken for warts. Plantar warts, however, typically show small black dots, which are tiny blood vessels trapped in the growth and absent in calluses. Furthermore, warts usually cause significant pain when squeezed, unlike calluses which are less painful under direct pressure.
How do you treat them?
Warts on the hands and fingers generally respond better to treatment than those on the feet. Treatments for plantar warts vary widely, including chemical applications, surgical removal, and even duct tape. The variability in treatment effectiveness indicates that while some methods work well, others may not. Foot specialists often have preferred treatments that are effective in most cases. Initial treatment typically involves topical medications applied over a 6-10 week period, with an emphasis on keeping the feet dry. In some cases, medications to reduce sweating may be used. If topical treatments fail or warts spread, more invasive options like surgical excision may be considered.
