I had that last week. My throat burned for about 2 days...I couldn't even talk, it hurt. I tried Thayer's Slippery Elm Throat Lozenges and it helped. It also went away in 2 days, but would have regardless of the lozenges. My doctor said the irritation can last a few days. You can get these lozenges in a health food store. Try not to eat for 2 or 3 hours before bedtime so this doesn't happen again, but all of us occasionally get a "sour burp" even without reflux disease. What you are feeling is normal after the acid...it is very strong. You will be fine. Let me know when it stops and good luck.
