I did not have that happen with my nostril, but I have to tell you that NG tube is the worst thing I have ever had happen to me, as well.
With 2 natural childbirth deliveries [probably wouldn't do it that way now, though ] and my 2 major open abdominal surgeries within 13 months of each other...the NG tube was hands-down the worst. I developed Ileus after my 2nd surgery last July and needed one for a mere day and a half and thought I would die.
I thought it was in wrong...HA! Now, after reading of others' experiences I know that is just the nature of the beast. My throat hurt so bad and every time I finally would drop off to sleep with it, I would have to swallow and wake right back up.
