Verrucas may at some point appear on the soles of your feet and look circular with tiny black dots under the hard skin. They are obtained through coming into contact with contaminated surfaces or close skin contact with someone who already has it themselves. It is a virus and so it can be spread from person to person and is more likely to happen if your feet have any broken skin, are damaged or wet. Verrucas can go away naturally or last anywhere between 2 to 10 years. A technique we use to treat stubborn cases for adults only involves ‘needling’. This is a procedure whereby the verruca is repeatedly punctured with a small needle many hundreds of times to cause bleeding and this in turn, stimulates the body’s own immune system to tackle the problem with the best chance of success.
