<unk>  is the feeling of burning or pressure inside the chest. Due to its location, it can be mistaken by chest pain and presented in life-threatening diseases such as acute coronary syndromes, aortic dissection and pericarditis. The pain can last for several hours and may worsen after food ingestion, in contrast with chest pain due to cardiac reasons which worsen with exercise. Some patients may also have a peculiar acid taste in the back of the throat accompanied with excessive salivation, regurgitating gas and bloating. The most common cause of<unk>  is gastroesophageal reflux disease (GERD), in which the lower esophageal sphincter allows for gastric content to reflux into the esophagus. This may also cause atypical symptoms which includes: coughing, wheezing or asthma-like symptoms, hoarseness, sore throat, dental erosion or gum disease, discomfort in the ears and nose.<unk>  is a symptom though, and it can have other causes besides GERD, such as esophagitis (infections, eosinophilic) and esophageal cancer.
