Heartburn!

Sunny

I've been facing severe heartburn for 2 days now! Never been one to have heartburn so don't even know if that's what I'm facing but it's like food is stuck at the chest or throat for hours. It's so uncomfortable and I can't eat for hours until the feeling goes away normally once I sleep and wake up. Any help or suggestions?? I've tried Tums but it doesn't seem to work wonders like I thought.
