Ive had the vessels in my nose cauterized, due to excessive bleeding. I think that it ranks right up there with the most painful ordeals that I've ever experienced. The doc used a tool that was no different from a blow-torch. BTW the anesthetic is minimal due to the location of the vessels. Lets just say that my ass didnt touch the chair the entire 2 minutes that he was operating. ( I must have really pissed that SOB off, maybe thats why he didnt use the anesthetic)
