So sorry to hear that you are as miserable as I was a few years ago…
Bloated stomach, like 8 months pregnant, an hour after every meal. No matter how tiny it was. Gastro doc did no tests except barium swallow which was ok, and told me to follow the FODMAP diet, no other info. 😱
Reached a point where swallowing sounds like your horrible issues.
I went to a local health supplement store, (not chain-but probably a chain might be able to help you,) and told them my problems after I couldn’t eat and I’d lost about 10 pounds in about 3 weeks. I was dizzy and didn’t feel really that safe driving. They recommended a
“porcine enzyme” (pig) to help with digestion. Surprised. I was desperate and took them. Amazingly, it worked!
If I remember, capsules and powder, capsules could be opened and mixed with water, etc.
Scheduled visit with Gastro and brought them with me to show him what helped. Anyway, he looked at them and said there were better things than this(?)Then he walked out…
Stunned, that was the motivation to move on.
Got an appt with new Gastro and had 4 tests within 2 weeks. And an upper endoscopy
1 week after that.
I had SIBO, (diet and expensive medication to fix;) bellybutton hernia, hiatal hernia, acid reflux, and my esophagus was tight and he stretched it when did the endoscopy. Not painful after.
I also have severe scoliosis, don’t notice it, thank the Lord, and that can also be pressing on my esophagus. I’ve had the stretching a couple times, and sort of an instant fix for swallowing.
I take famotidine, 20mg, down from 40.
It’s hard work to get things in order, and it took a couple years to really get the concept of “small meals”, after 3 meals a day, my whole life. Learned that a meal can really be just a tasty snack.
Of course, you may not have any of these things, but the porcine enzyme and the stretching helped me reach a point where I could work on the rest…

Maybe a new doctor?

Good luck!
