My father had a cancer in his oesophagus so they removed a part of him stomach and reattached it to his oesophagus. It has been a year since his surgery and every time he eats he feels his throat burn, his eyes begin to water and he moans in pain. He has done a endoscopy and an x-ray and nothing appears to be wrong. Every day it gets worst and we don’t know what to do. Our only hope is an ENT doctor.. please has anyone felt like this?

Sounds like he needs to see another GI surgeon.

I'd get a second gastroenterologist opinion because that definitely doesn't sound right. Wishing him the best.
