This is one that you must discuss with your doc, or if you are able to refer yourself to a podiatrist.
Verucca treatments destroy not only the verucca but damage the skin around and beneath it. Many people with diabetes have problems with the blood circulation to their feet and may not heal well. They may also have a loss of feeling to their feet and not realise the damage that is being done, This can very quickly lead to serious problems.
I has a small verucca when diagnosed, it had been there for ages but wasn't any problem. My doctor referred me to a podiatrist but I delayed it for a while, then one day I realised it was gone!
