My ds has a wart on his finger. We went to the chemist and they gave us Wartner which we used for four days. The wart changed colour and now today around the base it is all red and slightly bleeding. It's not hot to touch and he says it doesn't hurt. It looks like it is going to fall out (if that is possible) but I am slightly concerned about the redness. Does anyone know if this is all part of how warts die?
