For the novel, see Heartburn (novel) . Heartburn, also known as pyrosis, cardialgia, or acid indigestion, is a burning sensation in the chest, just behind the breastbone or in the epigastrium, the upper central abdomen. The pain often rises in the chest and may radiate to the neck, throat, or angle of the jaw.
Three out of every 10 people experience heartburn on occasion, so it can be somewhat arbitrary to decide when heartburn should be called acid reflux disease. Also known as gastroesophageal reflux disease (GERD), acid reflux disease is a chronic irritation of the lining of a person's esophagus by stomach acid.
