Tongue is in extreme pain after co2 laser procedure it has been five days now I am taking norco which is hydrocodone and acetamenaphin. I have also been taking some advil as well and have rinsed my mouth with hydrogen peroxide. Can not eat anything does anyone know how long the pain will last and any ideas to help which I guess is a burn heal faster. It is about 2.5 inches wide and goes down the entire side of my tongue is this a large area or typical?
