Hi,
I have something very similiar to that. Same pain, food won't go down, etc. My doctor called it dysphagia (or something like that) and put me on some pills to take once a day. They HELP! But, stress makes it worse. I tend not to take the pills all the time now, and most of the time I am okay, but sometimes I can't eat anything, especially bread products. Also, and this is weird, but raw baby carrots trigger it too. I end up having to "spit up" the food that is trying to go down. I have found if I do that, and then just wait, and relax, I can resume eating (although I have to eat very slowly and make sure I chew extremely well). When I take the medicine, I don't have this problem, or not near as much.
Hopefully, it will be something simple and you won't have to worry. It probably isn't a true blockage. I think with mine, it feels like the esophagus gets a spasm or something and closes almost completely, therefore, making the food stick there and it HURTS!! I also cannot swallow liquid at that point either, to get it to go down. Eventually, it all comes back up and I try again. But, the pills help. They have me on Protonix.
Good luck! Definitely go to the doctor though, ok?
