I'm not sure if this is in the right section, but I'll give it a shot anyway.
So I had some heartburn -- this is pretty frequent for me. I think it's genetic; in fact, I think I have some form of Acid Reflux disease, as my mom does. We'll get this checked out.
But first things first... I had heartburn. So I took some tums. About 5 minutes later, I just burbed -- JUST burped [I assumed from the chemical reaction between the HCl and the tums.] Suddenly, though, everything just turned to pain -- my entire throat, the back of my tongue, and even in my nose. At one point it felt like it was going to drip out. Mind you, this was no powerful burp. Just a small one. Another thing -- I've had heartburn before, but it's NOTHING like this was. This was awful -- painful, nauseating, and the taste was just terrible, very sour and metallic like, nothing like I've ever felt/tasted in my most extreme cases of heartburn. Also, I could feel what felt like sand inside my throat and coating my nasal cavity. This may just be the bits of the tums I took, but I'm not sure.
I know this all sounds disgusting... but it was frightening. It's never happened to me before, and I frequently get heartburn. This was not the same.
One thing: Two days ago I had a tetanus shot and meningitis shot to prep me for college next year. My right arm is still sore from the tetanus.
I don't know if these shots have anything to do with it or not, but I thought I'd include that.
