Reflux esophagitis can cause come back pain, mainly due to irritation of the esophagus by reflux material causing chest pain, which can appear as radiating pain in the back. In addition to back pain, it can also radiate to the neck, shoulders, and behind the ears, similar to the onset of angina pectoris. Therefore, many people with severe reflux esophagitis often visit the emergency room and are one of the main causes of non-cardiogenic chest pain. Because the chest pain is treated with emergency cardiology for coronary angiography, the coronary angiography examination is not problematic, and then the gastroenterology department is consulted for reflux esophagitis. So reflux esophagitis can also present with back pain, shoulder pain, neck pain, or chest pain symptoms, and when combined with heartburn and reflux, it is more important to consider if it is caused by reflux esophagitis.
