I'm sure others have tried viscous lidocaine? John was given an rx for it and he tried it optimistically three times w/absolutely no results--very disappointing! He's just using gobs of Orajel to what is the worst area so far, the right side of his tongue, although the throat is catching up fast. Norco helps some, but he's just completed week three and by all accounts here things are only going to get worse in terms of pain.
