idk what you want to call this but I have been drinking milk and water for hours now when I burp I have a little burning sensation in the back my throat my mom says it's heartburn I took tums but it's not going away!!!
Could also be some mild acid reflux. Go to a drug store and get Maalox. It's a liquid anti acid. Works wonders. Otherwise instead of regular tums I find Tums smoothies taste better and are cooler and "smoother" to take.
drink warm water like with no ice or coldness..i get heartburn so bad that anything i drink gives me it and only thing that works is sitting straight up when i sleep and warm water because i choke on the acid :/
