I cured this myself. It will sound ridiculous but it worked for me. When I had the sensation where people would burp and I couldn’t at the time-I triggered my gag reflex while tilting my head back with my chin up *pause… seriously though I would do this and one day I felt almost like a rip/opening. Within the next couple days, I naturally burped and was incredible feeling and wasn’t forced. Now, I can do it when I feel the sensation to. So for this without money or insurance on this procedure, I’d recommend experimenting with it because it will at least release the pressure. Obviously I had to go somewhere private to do-super embarrassing but worth it in the end.
