Verrucae are a common foot problem that can affect a person at any age, although the more often you are barefoot in communal surroundings, the more likely you are to catch them.
A verruca (or wart) is caused by an infection of the skin. They can occur anywhere on the foot, The build-up of hard skin may cause discomfort, but more often they are purely a cosmetic problem.
A verruca can last for several years and may become more painful with time and treatment options can vary depending on the infection.
Most over the counter verruca treatments contain salicylic acid, which is applied to the skin on a daily basis. To be effective, it is necessary to rub down the build up of callus/hard skin so that the acid can work. You should be prepared to treat the verruca for 3 months of daily application to increase your chance of success.
This method freezes the infected skin using very cold gas. When the verruca are frozen, the fluid inside expands and bursts, exposing the virus to the immune system.
For stubborn verrucae that have resisted all other treatments, a local anaesthetic is injected into the foot to numb the verruca. The verruca is then perforated with a needle to break it down and to push the viral fragments deeper into the tissue so that the immune system can come into contact with it and produce the cells required to destroy it. This can take 2-3 weeks to fully heal.
