Chest pain when drinking and swallowing is mainly considered to be related to the damage of esophageal mucosa, such as pharyngeal infection, reflux esophagitis, esophageal foreign body, esophageal cancer and so on. 1. Pharyngeal infection: after upper respiratory tract infection, redness, swelling and oozing in the throat will lead to pain and discomfort when swallowing. 2. Reflux esophagitis: gastric acid burns the mucosa of esophagus, which will cause related symptoms when swallowing, mostly accompanied by belching, heartburn, chest pain and other symptoms. 3. Foreign body in esophagus: if the esophagus is scratched by foreign body or the foreign body remains, it will cause damage to the surrounding mucous membrane when swallowing, which will cause pain and discomfort and other symptoms. 4. Esophageal cancer: Tumor causing destruction and invasion of surrounding tissues will also cause related symptoms, and most of the symptoms will continue to worsen. Chest pain when drinking and swallowing can also be seen in other diseases, and it is suggested that patients should consult doctor in time to clarify the cause of disease and treat it actively.
