This may seem weird, but I'm not sure if it happens to anyone else? For a few months now, I've been so worried about LPR that I've stopped myself from belching. I swallow gas back down again; of course that means my body keeps trying to belch, but I'm so worried about pepsin getting to my nose and ears that I've kept at it and kept the gas down. This is probably what caused my throat to gurgle so much.
Now I've been trying to let a few burps out, just to see what happens. Every time I do, my nose begins to run and my throat tightens up. I also seem to taste" the burps a lot more, and mucus moves up my throat. I'm not sure if this is down to anxiety or not, but you might say I have a phobia of belching, as it always reminds me "I might have an incurable illness here."
