Ordinary plaster will not do. It reduces the pain but does
nothing to help. You need to get Corn Plaster from the pharmacies
which will treat the infected area. Alternatively, visit a GP for
treatment. Most likely, you'll be given liquified nitrogen to
freeze the infected area until it reduces and drops
off..........
If you want to go commando and save money, , pluck it off! Once it
comes off with the roots, you'll be fine once the wound heals and
there'll be no regrowth. But if only the head comes off but the
roots remain, it'll regrow.......... Good luck!
