what does heartburn feel like?


I've been having this pain in the middle of my chest it comes and goes. Today it started when I laid down on the couch on my back. Ive been googling what heartburn feels like at it says burning in your chest. I don't understand how you can feel burning in your chest. I just don't get it. I feel like I swallowed a whole Dorito or something really sharp and it's in my chest. Whats a good explanation besides burning?
