Welcome to Ask The Doctor.
I understand your concern.
This really happens when you are for a long time on feeding tube. This goes away with time. In my opinion, you should wait for a few days.
You should start with liquid diet initially and then progress to semi solid and later normal diet.
In severe cases, we prescribe Xylocaine Viscus which helps greatly.
Share my opinion with your doctor.
I hope it helps.
