I have a problem swolling some foods frequently, mostly meat whether chicken, pork, steak or hamburger meat...it doesn t matter (although it doesn t usually happen with fish). At least a couple of times I have had it stuck all night long because I couldn t get the food to move up or down, even drinking liquid...it just sit on top of the obstruction and I throw it up (this happened again last night and I was afraid to lie down, afraid I might choke). It finally moved down into my stomach this morning but it was a very painful night and that area still feels sore. The offending food last night was one bite of hamburger meat.
