Hi there, this part of my story is SO mild compared to yours. When you say, need to burp, have you considered using club soda: no flavor, but nothing that might make it worse. My throat just randomly seems to get really narrow, I've only missed the sink, garbage can, toilet 1x, I pulled my shirt up and let it all out. I also use the club soda to gargle, hard and deep (over the sink of course), it feels like it breaks through either the thick mucus and/or opens up my throat. I get the pressure from throat-neck-shoulder-top and back-down into chest-down ribs to hips, mostly left side. The burning, I swear my chest is actually on fire, I squeeze it so hard, I think I might break a rib. My motility is really almost dead in my intestines small and large...hence constipation that is worse than childbirth. Anyway, I bring this up, because I have had CIC for 17 yrs, literally tried everything meds, natural, etc... I just got my second opinion that I have had PRIMARY Hyperparathyroidism for probably 10+ years. So I have to get surgery, I am actually relieved, and I'm hoping that this will help with my OMG multiple issues. My case is screwy but my doctors never ever mentioned that high calcium levels, 15 yrs ago when it took them. (PCP, ENDOCRINOLOGY AND GI) 4 yrs to diagnose me with secondary Hyperparathyroidism caused by malabsorption... I have Celiac disease, congenital but asymptomatic. Elevated calcium levels wreak havoc on our smooth muscles ( our intestines) . I don't know if your motility issues extend into your pooping life... but mine just doesn't seem to work at all, has gotten much worse after obstructions. So, I have to keep my body in a very liquidy state. Anyway, I thought I would share this. BTW: parathyroid has NOTHING to do with thyroid, they are just in your neck.
Good luck with your health 🌼
