The aim of treatment is to remove the wart with no recurrence and to induce lifelong immunity; the immune system plays an important part in this process.
Most patients with verrucae will already have tried several over the counter self treatments without success. This is often because the verruca is pushed inwards with callus forming, so presenting a barrier for salicylic acid and freezing treatments and making the file that comes with the kit ineffective. The only way to remove it sufficiently is with a scalpel (which is not painful) and this can only be done by a foot health practitioner or podiatrist, do not attempt to do this yourself. You will be advised to discuss with your pharmacist which topical treatment is best suited to you although no treatment has been proven to be 100% effective.
Avoid touching or scratching verrucae as they may spread into a cluster of warts. Instead, cover them up with a plaster. If you wish to go swimming, verrucae socks are available to stop you spreading the condition to others.
If verrucae remain troublesome, you have the option of being referred to a podiatrist who is qualified in more advanced treatments including:
acid based treatments which are stronger than regular ‘over the counter’ (OTC) treatments
cryotherapy which involves freezing the verruca with liquid nitrogen or nitrous oxide gas
electrosurgery which requires a local anaesthetic to be given
excisional surgery which is similar to the above
laser surgery, particularly for larger areas of verrucae
