A burning pain in the chest or throat, caused when stomach acid backs up into the esophagus.

Abdominal discomfort with retrosternal pain usually associated with gastroesophageal reflux.

Heartburn is a painful burning feeling in your chest or throat. It happens when stomach acid backs up into your esophagus, the tube that carries food from your mouth to your stomach. If you have heartburn more than twice a week, you may have GERD. But you can have GERD without having heartburn. Pregnancy, certain foods, alcohol, and some medications can bring on heartburn. Treating heartburn is important because over time reflux can damage the esophagus. Over-the-counter medicines may help. If the heartburn continues, you may need prescription medicines or surgery. If you have other symptoms such as crushing chest pain, it could be a heart attack. Get help immediately.

Substernal pain or burning sensation, usually associated with regurgitation of gastric juice into the esophagus.

Heartburn is a burning pain in your chest, just behind your breastbone. The pain is often worse after eating, in the evening, or when lying down or bending over.
