I have that happen randomly. It can happen a few times a week, or not for a few weeks. It can happen with hot food, cold food, or just spit. It's as though my throat or esophagus spasms, and maybe that IS what happens.

Sometimes I can just wait a few seconds, try to relax, and let it dissipate. Other times, if I'm trying to swallow food, it's sort of like GERD on steroids. It won't go down or come up, and it almost feels as though my chest is clenching. Or something.
