I'm surprised that the doctors went with the NG tube instead of a PEG. Given the size of the tumor I'm sure they had to have some kind of ideas of following up with radiation treatments. I had a PEG in from the surgery until about 2 weeks after radiation treatments ended. It was an annoyance having it there since I wasn't using it at all. Then I got to that last week of treatment and was very glad to have it. Anything other than water was unbearable on the mouth sores. I'm sure the NG tube is just as annoying, and with radiation it may become downright painful. I would definitely talk to docs about getting a PEG though. Even if it's just to throw down some extra calories while giving the tongue a break.
