Verrucas are small, rough lumps, warts or growths found in the heels and balls of the feet that bear pressure. If you have ever experienced a verruca before, you will know the stigma that often comes with them; they can be painful, a source of embarrassment and impact you partaking in the activities you love.

Verrucae are the result of a viral infection known as the Human Papilloma Virus; they are highly contagious and can be extremely difficult to treat. More often than not, verrucas will usually resolve on their own, but several treatments are available if they begin to cause problems, such as Swift microwave therapy. The most conventional methods of treatment are cryotherapy and acid therapy. However, these can be painful and often quite inconvenient due to the aftercare dressings affecting day-to-day life.

Swift Microwave Therapy is a new innovative form of treatment developed in Scotland and licensed for the general treatment of skin lesions in podiatry and dermatology. Swift uses microwave energy delivered through a special probe applied to the skin to treat the affected tissue.

How does it work?

A single-use applicator tip is used to deliver energy into the skin at a predetermined depth, several mm below the skin’s surface. This precise and highly controlled energy dose rapidly elevates the tissue temperature. As the microwave energy travels into the tissue, the water molecules attempt to align with the microwave field, causing them to collide and create friction. The heat generated creates a highly effective zone of treatment.

Once this short treatment has been completed, the healing cascade begins immediately. Treated tissue is quickly repaired, replaced and regenerated.

Similarly to many treatments for skin lesions, you may experience a small amount of discomfort during the procedure. Most people who have undergone Swift microwave therapy compare the pain to a scratch or injection, lasting a few seconds but promptly subsiding. One of the significant benefits of Swift microwave therapy is that no dressings are required afterwards, and the skin does not need to remain dry, meaning you can quickly return to your daily routines.

With a few exceptions, almost anybody with a verruca can undertake this treatment. However, it is always best to see your podiatrist beforehand as they can carry out assessments before the procedure and provide expert advice.
