Nelie,
I hope this is not a dump question. I am sure you have had a swallow test. Right? They need to do one and see how you are processing it and how far. I can not believe you are still having so much trouble. I think they are missing something.
I had one done and they could see how far and where it was hanging up. They also found on the first Dilation a web like scare that would go up and down when I would breath. This accounted for the times I could swallow fine and other times I could not. I just had my 2nd dilation done.
Hope you call & tell them what is going on.
Take care,
Diane
