Five days post op from tonsilectomy. As of last night I have an intense burning sensation on the right back side of my tongue. It is excruciating and I am unable to drink water, or even allow any liquid to touch the tongue without dropping to my knees in

See doctor. Typically post-operative symptoms should improve gradually with time. With such severe pain causing you to drop to your knees 5 days post-op, I would be seen by physician in person so a comprehensive physical exam can be completed to look for any signs of infection or surgical complications.
