Esophagus usually refers to the esophagus. Pain in the esophagus when eating and swallowing may be caused by esophagitis, pharyngitis, esophageal injury and other reasons. 1. Esophagitis: Inflammation of the esophagus causes damage to the esophageal mucosa and erosion, which is why you feel pain in the esophagus when you eat and swallow. 2. Pharyngolaryngitis: Acute inflammation caused by pathogenic bacteria infection in the throat, such as acute tonsillitis, acute pharyngolaryngitis, acute epiglottitis, etc., which causes local tissue congestion and edema, and causes pain in the throat when swallowing, which is reflected back to the entrance of the esophagus, causing pain in the esophagus. 3. Esophageal injury: Eating hard food or bone piercing the throat area can cause pain in the esophagus when swallowing. If you feel pain in the esophagus when swallowing, there may be other reasons, such as laryngeal cancer, esophageal cancer, etc. It is recommended to consult a doctor in time to find out the cause of the disease and follow the doctor’s instructions to avoid delaying the condition.
