Oh yes!!! it's an awful sensation isn't it!! It almost gags me, feels like my throat is collapsing... it got so bad once my voice coudln't come threw my collapsed throat - i would try to talk and almost sounded like kermit the frog- of course I had a lovely nasal voice as well.. it was AWFUl for a few days until I got IVIG .. it completely went away all winter long - and now that it's warming up it's coming back grrr.. (again, I don't have a firm diagnosis though - but seroneg MG is high on the list).
