Verrucae are caused by the Human Papilloma Virus (HPV). They can occur at any age, and on any area of the feet, but are most common in children and people frequenting communal changing areas, e.g. gyms etc. They are a completely harmless 'benign' growth, which, given time (in the vast majority of cases) will resolve untreated.

However, this can take many months, sometimes even years, and left without treatment may develop into a larger growth, or become more numerous. There is, therefore, no right or wrong answer as to whether you should treat them it depends on your personal circumstances.

Home treatment involves applying either acid-based treatments or a cold cryogenic spray, based on those offered by healthcare professionals, called dimethyl ether. Both have the same goal, which is to damage the cells of the verruca, which ultimately will stimulate the body's immune system to eradicate the virus. Home treatment is generally successful if offered before the verruca becomes too large, in which case professional treatment should be sought.
