What sqad says sounds horrific, but it works a charm.
I had a verruca when i was very small. I'm a bit of a picker though.. Like i love picking scabs etc..
As i picked at this verruca, yes it hurt but in a odd nice way, like picking a scab the whole thing came off root and all. It was like a wart, with a solid white hard root going into my foot. The whole thing came out, and there was no blood. Never got one again. Very odd i know, but maybe try pick it off?
It's important to know, my verruca was dead, as there was no blood flow to it. I imagine if the verruca is alive, it will hurt and bleed more.
