I all of the sudden cannot drink water, or basically anything. It leaves a rancid aftertaste in my mouth. It is semi-present in lemon-lime Gatorade, but it just all of the sudden popped up. I haven’t eaten or drank in the past couple of hours now, I’ve been crying, I don’t know what to do anymore. Please help me.

If it helps, I’m 17, and like I said, it’s day 10 of a Tonsil removal, I had my adenoids out when I was a little kid.
