as said its a viral infection (hpv virus)
we are told nowadays that treatment should only be offered if the lesion is painful or spreading otherwise leave it be for your own immune system to take care of.
most treatments centre around tissue destruction.
cryotherapy (freezing) is the first line treatment modality offered or salicylic acid (try to find something strongish 'verrugon' is my favourite at 50%. READ the label and dont use if contraindicated or you may end up with holes in your feet) bazooka etc are around 26% acid so gentler, another good one is occlusal.
the gaffa tape thing you should gently file the lesion apply the tape then leave for 6 days remove file and repeat etc etc it is thought that the adhesive in the tape stimulates an immune response.
above all they are very contagious so if you live with others then cover it up!!!!
there are no quick fixes for some people, i used to work in an nhs wart/verrucae clinic and we had people coming back for treatment once a week for 6years!!!!! (extreme cases though admittedly)
hugo… the local nhs PODIATRIST (as we are now called) wont treat a verrucae under the nhs unless it is very bad, unfortunately for the general public our services are now generally reserved for high/at risk patients nowadays.
banana skins lol if i had a pound for every time i have heard that
