Does it ever burn when you take a sip of a soft drink?

Why? Or is it “Why me?” I just took a sip of Diet Coke, my first of the day, and it burned all the way through my chest. It took like 2 minutes for the burning to stop and then I thought about it for a little while and tried another sip of Diet Coke and it was fine. I don’t think it went down the wrong pipe or anything since I didn’t cough, I just ran around in circles trying to burp and saying “owwwowwwowww!” Nothing helped until it faded. I’ve done this a few times before, but its been a long time. I don’t think its anything to do with the Diet Coke since I drink them every day instead of coffee or other things like that.

So two questions.
1. Does this ever happen to you?
2. Why?
