Verrucae are plantar warts that commonly occur on the soles of the feet or around the toe area. They are caused by the Human Papilloma Virus (HPV), which is contagious through direct person-to-person contact. There are various forms of HPV, which all relate to various parts of the human body.
If you are worried about your verruca and/or self-treatment is not working and/or the verruca appears to be getting larger or more painful, visit a chiropodist/podiatrist.
