It is possible that some amount of soft foods are sticking in your throat -- probably your epiglottic vallecula; this might be more apparent when you are having a mild allergic reaction, making that area of your throat more sensitive. (Wiki fails to mention that one of the functions of your vallecula is to catch bits of food that might be trying to fall into your windpipe).
It is also possible that one of your epiglottic sphincters, or the peristalsis in your epiglottis, has gone wonky, and food is having trouble making it to your stomach in a timely manner. As TezlaKoil says, in many cases this is accompanied by acid reflux. If you feel pain, see a doctor. Otherwise, don't worry too much, but eat sitting up straight and take a swallow of water when you have this feeling.
Since you know something about these things, may I ask you a question? (I have consulted doctors, they didn't find anything, and it's just an annoyance really, but I don't know what it is.)
Sometimes, after I have lowered my head forward, or pillowed my neck on my arm, or just tightened my scarf too much, I straighten (or not) and am unable to talk or swallow. I breathe fine, only my throat (lower forward) pains a bit and feels as if it has bent backwards. I rotate my head from sides and massage my Adam's apple, and it goes away.
It's mostly just inconvenient, but sometimes scary, too:( (when I think that it might happen when I'm asleep.)
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
