Hi AJ,
I find your post very interesting. I also have the spasms. Do yours come in the middle of the night? Mine always come in the middle of the night and I've had them for years before I ever knew that I had GERD or LPR. I've had a sensitive throat for as long as I can remember. I don't really know much about them except they are very scary. My brother and father both have them so I thought it had something to do with our genes.
I hope someone here has some ideas as to what causes it.......maybe the vagus nerve? Although I've given up carbonated drinks, I will definitely keep one at my bedside for the next time I have one in the middle of the night.
Thanks for the suggestion.
I'm not sure what is a vasovagal attack?
