If you see a callous or hard skin anywhere on your feet, chances are it could be a wart, also known as a verruca; A subtle difference that only a podiatric specialist may be able to diagnose. They are viral in origin and most usually are spread from contact with another person . Left untreated, a wart can spread and multiply, making treatment potentially more difficult and prolonged. Plantar warts can be raised or involuted depending on where they are located. Moist environments, as your feet may be when wearing thicker socks and boots this winter, allow warts to thrive. Treaments include topical and oral medications, as well as different lasers. We use a carbon dioxide surgical laser, as well as pulsed dye and Nd-YAG lasers that are less traumatic and require no down time. Remember, a callous is not always a callous !!!
