Chest pain when drinking water may be caused by reflux esophagitis, pleurisy, esophageal tumor and so on. 1. Reflux esophagitis: the reflux barrier in the gastroesophageal department is damaged, resulting in gastric acid easily entering the esophagus, the esophageal mucosa is damaged, and the chest will hurt when drinking and swallowing. 2. Pleurisy: if the patient has low immunity or does not pay attention to hygiene in eating, it is easy for germs to invade the chest wall and become infected with inflammation, and the irritation of inflammation will lead to chest pain when drinking and swallowing. 3. Esophageal tumor: patients with esophageal tumor itself may have chest pain symptoms, and when patients with esophageal tumor have esophageal stenosis, they may feel pain behind the sternum when swallowing. Clinically, patients with chest pain when drinking water can check the CT of both lungs and do esophagoscopy under doctor’s advice to clarify the nature and give symptomatic treatment as early as possible to avoid aggravation of the condition.
