Causes of air bubble in the throat while eating or drinking may result from swallowing air and when you eat food that is not chewed properly or drinking large amounts. Sometimes it really hurts really badly. You can visit a doctor for more advice.
were you drinking carbonated Soda?? if not then air got stuck in your throat...it hurts because the throat is very tender....gargle with some warm salt water...then do 30 push ups and 50 sit ups. then more sit ups...you will be so sore from those that you will forget about the air bubble...good luck hopes this helps...and Quit eating Bugs food..:)
I've the pain when I swallow spit, but not so much while swallowing mouthfuls of food or drink. I recently found out what my problem is. It's not actually the pharynx (swallow). It's the air that don't elevate to the ears while swallowing, because the channels are clogged. When swallowing air, it stuck in the swallow, which don't let it out, and every time I swallow spit (small amount of anything, actually) it just builds up to terrible highs.
I've found one way of relieving it. Use a "nose-horn" (or what you call it in English) pour several buckets into your nose, rinse with air, THEN use the "Vasalvas mamaneuver(blowing air while closing your nose with your fingers). When doing this several time, the opening to the ears clears, and next time you swallow, there will not go (so much) air down into your swallow - and you might hear your ears "click", because they are relieving the swallow from getting air inside it.
I haven't found this explanation anyplace. I've just had to find it out my self, after months of pain-hell...
