Have you ever heard of Jack Hammer Esophagus? That’s what I have and I had the same symptoms. It’s a rare disorder of the lower esophageal sphincter that malfunctions and the only cure for that is surgery unfortunately. They referred me to a motility specialist and did a test called Esophageal Manometry and found what was causing all my problems and symptoms. It’s a very uncomfortable test but it’s the only way to confirm diagnosis of the Jack Hammer Esophagus. Look it up and see if this sounds like your issue.
