Spasms for sure or the other one is feeling and knowing the food hasn't gone down and is on it's way out again - usually either in the car at traffic lights (true story) or on a train (seriously, I'm not making this up!)
Sometimes, on good days I can work through them, on others it feels like I'm about to have a heart attack.
I've also had a twisted esophagus during a spasm which resulted me in being rushed to the hospital - the cardiologist thought I might be having a heart attack and very quickly slipped beta blockers under my tongue.
