Difficulty swallowing food

Swallowing disorder, or dysphagia, occurs when a patient experiences pain while swallowing. Sometimes they cannot swallow at all, and food may enter the nose or trachea. Pain caused by inflammation of the oral cavity, pharynx, or esophagus often leads to a swallowing disorder. Ulcers, injuries, or less commonly, glossopharyngeal or lingual pharyngeal nerve neuralgia, can also cause this disorder. Sometimes, a tumor affecting the esophagus, scar tissue after injury, or congenital defects impair swallowing.
