The New Way to
All our podiatrists regularly attend conference seminars where we continually aim to expand on our knowledge as well as keeping up to date with new methods of treatments, this enables us to provide the best evidence based treatment plan and advice for our patients.
Cryotherapy, also known as liquid nitrogen, is a treatment option for treating verrucae/warts and has been around for many years. Cryotherapy involves destroying the viral cells by subduing the virus to very cold temperatures, destroying them.
The area is frozen creating an ice ball which causes destruction to the virus and surrounding cells. The damaged cells rupture releasing the virus into the bloodstream where they are removed from the body by the immune system.
What Does Cryosurgery Involve?
- The skin is prepared removing any callus and dead skin surrounding the verruca/wart and then sterilised with skin disinfectant.
- The liquid nitrogen is sprayed for couple minutes with intervals of rest and re-application
- The area is dressed and the podiatrist will give you the appropriate aftercare advice necessary.
Will It Be Painful?
During the treatment, very little pain is experienced and usually feels very cold with a little stinging sensation which would ease off within a few minutes. After the treatment, the area should blister within 24-48 hours (this can be delayed in some patients). If discomfort is felt during this time it is advised to take painkillers such as paracetamol which will help to eases the discomfort.
On some occasions the lesion can bleed under the skin forming a blood blister. This is a common consequence and is nothing to worry about. The area needs to blister to eradicate the verrucae/wart. If you have any concerns our team are available on a 24-hour emergency telephone number.
Follow Up & Redressing?
Your podiatrist will advise on the appropriate dressing to use in between appointments.
The verrucae/wart will be assessed 7-10 days post-treatment. If necessary, the podiatrist will freeze the area again. Some verrucae/warts can be resilient so may require multiple treatments. Your podiatrist will discuss this with you during your initial appointment.
