When it comes to treating a plantar wart, burning or cutting it out is only really advisable if it is not on the part of the foot that touches the ground. If it is on a weight bearing surface, these methods shouldn’t be used as a first resort as they will leave a scar that will probably cause painful corns in later life. In our clinic, we commonly use chemical cautery as it is one of the most friendly of approaches for removal. Depending on the size of the warty lesion, the wart may be shrunk first with a three day application of a slow acting chemical. This generally does not cause any pain at all – but it rarely will get the job completely done. When the size of the growth is more manageable, the wart is then killed with a quick acting chemical which takes just a couple of minutes to work. It is done under local anaesthetic injection.
This approach is also likely to be the least painful in the long run as the chemical forms an immediate scab over the area, protecting the new wound and at the same time cauterizing the nerve endings. We don’t need to take a margin around the wart and can leave the dermis intact, meaning that scarring of the foot is unlikely, as the chemical used shows a distinct preference for dissolving the wart tissue rather than normal skin tissue. Freezing of the growth is another option. While good for warts on softer skin, on the plantar surface / sole, it will usually require multiple applications and may be as much or more painful than chemical cautery, both at the time of application and over the following days. On the upside, it does not require an injection and may be more suitable for children or for killing off a wart that is still quite small.
