I am 19 years old, female, healthy, normal eating habits, etc, but I do not burp. I've tried drinking soda, swallowing air, etc, and it just makes me feel uncomfortable but doesn't make me burp. Instead, my throat gurgles. The best way to describe the sound is like a stomach growling, only in the throat. It's incredibly embarrassing and I can't prevent it from happening. It tends to happen a lot after I drink juice or soda, but also sometimes after meals where I only drank water. Along with the gurgle I feel some light pressure in my lower throat, near my collarbone, like there's air trying to get out (no pain). The pressure is momentarily relieved after I "gurgle", but then it comes back and I need to "gurgle" again.
I have met one or two other people who experience the same thing, including my sister, and seen other complaints online, but have found no explanation for why this happens, or how to prevent it. Any help?
I very rarely throw up either (only once in the past 8 years), I don't know if that's connected at all but I thought I should mention it.
