Chest pain when swallowing may be related to pharyngeal infection, reflux esophagitis, esophageal foreign body, esophageal cancer and so on. 1. Pharyngeal infection: upper respiratory infection causes redness, swelling and oozing of throat tissues, which can stimulate the throat tissues to produce pain and discomfort when swallowing, and patients feel chest pain when swallowing. 2. Reflux esophagitis: gastric contents and acid reflux irritate the esophageal mucosa, which causes pain and discomfort when swallowing, and is often accompanied by belching (burping), heartburn and acid reflux. 3. Foreign body in esophagus: When the esophagus is scratched by foreign body or foreign body remains in the esophagus, it will cause damage to the surrounding mucosa during swallowing, which will cause pain and discomfort. 4. Esophageal cancer: the tumor infiltrates and invades the surrounding tissues, causing ulceration of the esophageal mucosa, resulting in dysphagia, pain in swallowing, emaciation and other symptoms, and the symptoms continue to worsen. There may be other reasons for chest pain when swallowing, so you should go to the hospital in time to check it out and find out the reasons and then treat it under the guidance of doctor.
