It went away Monday morning, and came back Wednesday night. But this time, as the sore throat progresses, it feels more like heartburn or something. It starts pretty much in my mouth, and goes down to my stomach, and it just feels kind of...acidy? I don't even know how to explain it, but it kept me up all night. It makes my stomach upset, and makes me feel a constant need to burp (too much information yet?).
So, I'd appreciate any ideas on what it might be, and anything I could do to make it go away. Thanks!
