I can't burp (manually or otherwise) and so frequently feel awful/bloated/nauseous after meals. What is this?
I'm trying to track down the cause of a problem that isn't heartburn, isn't just gas, and isn't anything else in particular insofar as it seems to have a very particular set of symptoms and (lifelong?) traits. To wit:
1. You never, ever vomit (and it's totally debilitating if/when you do)
2. You are unable to burp, manually or otherwise
3. Air/gas gets caught somewhere between the stomach and mouth, making an up-and-down gurgling noise/sensation, followed by a sense of pressure in the lower throat which can become almost painful and causes waves of nausea
4. Because of these, the person tends to avoid carbonated drinks totally as they can ruin the evening of such a person by causing lots of pressure and nausea
5. Standard treatments for gas/heartburn/acid reflux (including things like Pepcid, Rolaids, and Tums) either don't affect the symptoms, or do so poorly and slowly
Anecdotally, one night I took the maximum dosage of Gas-X for as long as I had the sensation starting at 8:00PM (the nausea was very bad that night and I was sick of it) until eventually, at 3AM driving home, I thought for sure I was about to throw up (to reiterate, this is the worst thing I can imagine short of losing a limb). I pulled over, there was a horrible wrenching sensation, and giant geyser-burps shot out of my throat. Shaking, I drove home without any further symptoms.
I Found a few people describing this same basic thing here.
Any ideas what would cause this? As someone who doesn't currently have health insurance, my options for addressing/professionally diagnosing this aspect of my life are pretty limited but I'd like to at least know what might be causing it. Is it perhaps a hiatal hernia, aggravated by overeating and compounded by infrequent GERD?
