It sounds like esophageal spasm followed by globus hystericus. Itīs all triggered by GERD asnd anxiety. I ended in A&E last week with this symptoms fearing the worse and they said it was an esophageal spasms. Itīs very painful and the only thing that might relieve it is Prilosec or muscle relaxants. They can come and go I have been dealing with them for the last 10 years and always come to visit me when I am anxious about something. The best thing is relax but sometimes itīs difficult depending on what is giving you anxiety.
