Esophagitis may cause right chest pain and shortness of breath. After suffering from esophagitis, the superficial or deep tissues of the esophageal mucosa will be stimulated or damaged, which will lead to congestion and edema of the esophageal mucosa, causing inflammation, such as reflux esophagitis and radiation esophagitis, and the patients will mostly experience esophageal symptoms such as heartburn, dysphagia, acid reflux, belching, retrosternal pain, and epigastric pain. The clinical manifestations of esophagitis have extra-esophageal symptoms in addition to the esophageal symptoms, and the common ones are throat discomfort, foreign body sensation in the pharynx, cough, asthma and shortness of breath. Patients with esophagitis who are accompanied by uncomfortable symptoms should go to the hospital in time for examination, diagnosis and treatment under the guidance of the doctor to avoid delaying the condition.
