I have this thing that happens when I eat or drink things that are very cold, like ice cream, or cold drinks. it feels like the food gets stuck in my throat, and even sometimes regurgitates. it is at the bottom of my neck near where the collar bone connects with the neck. What could that possibly be. I saw a head and neck doctor, and he look down my throat and did not see any growths, he said because of my age it was possibly muscle spasms, but I am not yet satisfied with that as it seems to be getting worse.
