Anyone else have a “tight” esophagus?

This is kind of where my harder days started. A pain/lump feeling in my stomach that’s now followed me around for a couple of years. I also feel like air gets trapped, and it’s hard to burp it out. Then I get tightness in my esophagus where it feels uncomfortable to swallow food sometimes, and it sort of spasms when I swallow, and some air can come up at the same time. I’ve had a manometry and upper endoscopy done, but to no avail. I’m in a flare (dysautonomia or MCAS, not sure) and this tightness is especially bad today. Ugh.
