Hi-ya ImHat
You should not try to gouge warts or anything to cause them to bleed (if possible) as i have heard it can bleed back into the boodstream and then you have the virus for life (in yr bloodstream) which can pop up anywhere on the body.
Both of my kids had warts on their hands and fingers for a few years (my sons were the worst) we were told (an old superstition) that if some1 buy's them off you they will go away. So my kids grandfather brought my daughters warts & they did go after a couple of months (we had had hers burnt off at the doctors also & it didn't work).
My son (who had also been treated by a doctor many times for them and never worked either) then asked his uncle to buy his warts, he asked how much would you like...my son said anything will do

so he brought them for $1.60 or somthing...well that didn't seem to work so i treated them with "extra strengh Duofilm Gel (which needs to be applied once a day for as long as it takes) this did work although it took quite a while...they have never returned.
