I get hiccups all the time, but thats the phrenic nerve. I too get the feeling that I have something stuck in my throat, even if I havent swallowed anything.

you must be very mindful of every bite you swallow. Dont eat while distracted. sit at the table and concentrate on your food, your nourishment, and sustanance. Slow down, taste your food and swallow eat bite thoughtfully till this passes. Mine comes and goes so I hope yours does too.
