Every time i talk or sing my throat closes up and hurts for hours and I think my vocal cords are swollen, i drink water and i don't eat a lot of acidic foods at all, i have really bad acid reflex and i think i have the silent reflex, i have all of those symptoms. I just don't know what is happening, this only started about 1-2 years ago out of the blue, i have had really bad acid reflex all my life, but now it doesn't burn like normal reflex, it just is a little painful in the stomach, my throat just hurts all the time and if i talk for more than 3 minutes it closes up and it feels like i am being choked, does anyone know what this could be?
