Sometimes, it may be necessary to treat a verruca if it is VERY painful.
If yours is causing pain, there are a number of treatment options available
– though no one particular treatment can guarantee a cure.
Verrucae generally resolve spontaneously within six months in children.
In adults, they can persist for years.
In short, you can treat your verruca with an over-the-counter medicine
unless you have diabetes or circulation problems.
If you do however, or find that the verruca appears to be getting bigger,
consult a podiatrist.
