I finally found a great ENT, the one who scoped me, who diagnosed me with a muscle spasm in
my larynx. I don't recall the medical
term, but he pretty much said take a muscle relaxer and if it goes away, that's what you have. And boom, I took one, and relief. It took a while for it to register in my brain that it was not something more serious and that it wasn't going to kill me, so I still had episodes for a while until I got control of the fear of it all.
