Why does it hurt every time I eat rice?

Might be a good question for a doctor. I used to get those types of pains when I was a teenage and ate bread. It was like a knot stuck in my chest that hurt like crazy. But mine would go away if I drank something. I'd get it checked with a gastrointestinal doctor. Perhaps a stricture of your esophagus is the reason, which they could find with a scope. Good luck!
