The feeling of blockage when swallowing in the throat, i.e. the feeling of swallowing a foreign body, may be related to laryngitis, esophageal cancer, epiglottis cyst and other reasons. 1. Pharyngolaryngitis: the mucous membrane of pharynx in patients with pharyngolaryngitis is congested and swollen, which can lead to narrowing of pharynx and blocking sensation when swallowing. 2. Esophageal cancer: some esophageal cancer foci are near the entrance of esophagus, with the development of the disease, there may be a sense of obstruction when swallowing. 3. Epiglottis cyst: when the mucus gland ducts in the epiglottis area are obstructed, resulting in mucus retention and cyst formation, there will be a sense of obstruction when swallowing. Throat swallowing with a sense of obstruction, may also be caused by psychosomatic factors, it is recommended to go to the regular hospital in a timely manner to clarify the cause of the disease, under the guidance of the doctor for standardized treatment.
