Verrucas are a common condition and effect roughly 7-10% of the population. Verrucas are caused by human papilloma virus (HPV). Various conservative treatments are available such as chemical and physical which aim to distrupt the integrity of the verruca so that the cells in the skin can recognize and mount an immune response. Verrucas can take multiple treatments to clear. Your Podiatrist will give you a treatment plan that will take into account your medical conditions, severity, size, pain, and the length of time you have had the verruca.
