Hello,
I've had a verruca on my foot for maybe 5 years now 
Last summer it was painful where I was wearing sandals/flip flops but nothing would get rid of it.
Now we are back in sandal weather I really want this bloody thing gone!
So far I have tried;
Bazooca (or however you spell it.)
Superglue
Cider vinegar with cotton wool left on at night.
An over the counter freezing one which had a freezing "wand." Oddly that removed my son's verruca when he was about 4 (he's now 9) but not mine.
Wartie.
Nail varnish.
It's annoying me now because it's so flipping stubborn! Any more suggestions?
