Common causes of a burning sensation affecting the throat include a sore throat or a condition called gastroesophageal reflux disease, or GERD, according to WebMD. Laryngopharyngeal reflux, or LPR, is a similar condition that causes throat pain due to rising stomach acid, reports Everyday Health.
Many people occasionally experience heartburn after eating large meals or spicy foods, according to WebMD. This leads to a painful burning sensation in the chest and throat. Patients report that the feeling resembles a hot, acidic fluid rising from the stomach to the esophagus. While heartburn is usually not a cause for concern, it can be a symptom of a serious health condition called gastroesophageal reflux disease. If left untreated, GERD can result in a chronic pulmonary disease or in ulcers and inflammation in the esophagus.
Laryngopharyngeal reflux, also known as silent reflux or LPR, is similar to GERD but with the absence of heartburn, which is one of its primary symptoms, says EverydayHealth. Despite lacking a burning pain in the chest, many patients with LPR experience a wide range of symptoms brought about by the damage that acid causes to their throat, such as hoarseness, throat irritation, respiratory problems, tooth decay and nagging cough. Acid reflux into the back of throat causes atypical symptoms including constant hiccups and trouble swallowing as well.
