Heartburn, sometimes called acid indigestion, is a painful,
burning feeling in the middle of your chest or the upper part of your stomach. The pain, which can also spread to your neck, jaw, or
arms, can last just a few minutes or stick with you for hours. There’s a muscle
at the entrance of your stomach, called
the lower esophageal sphincter (LES), that acts like a gate: It opens to let
food move from your esophagus to
your stomach, and it shuts to stop food and acid from coming back out.
