I have the same problem!
I went to the hospital to have it looked at. They had me swallow (barium?) so they could see what was going on in the xray.
I guess it was not an emergency so they didn't seem to care and nothing was done about it. Still a big pain though and I constantly even get an air bubble in my throat that stops me from swallowing water sometimes.
Makes it really annoying when I have a cold and stuffed up nose too because swallowing is that much tougher.
Hope you figure it out!
