What is heartburn? It has nothing to do with the heart. The term is used to describe a painful burning sensation in the throat and chest. It often originates in the chest and may then radiate to the neck or throat. This pain results from the reflux of digestive juices containing hydrochloric acid from the stomach into the oesophagus or gullet. The medical term for it is GERD (gastro-ssophageal reflux disease).
