The typical symptoms of GERD are heartburn, acid reflux, regurgitation and pain behind the sternum, pain mostly behind the sternum or under the raphe, with pain or discomfort that can radiate to the upper chest, shoulder, back or even ear, and the pain is mostly intermittent, mostly related to meals, can wake up at night with pain, and affected by emotions, If stomach pain and shoulder pain occur and disappear at the same time, GERD is mostly considered. If the tumor tissue of gastric cancer metastasizes to the scapula, both pains can occur, but we should also exclude the possibility of stomach disease and frozen shoulder at the same time. In conclusion, when the above mentioned discomfort symptoms appear, it is necessary to consult a doctor in time, to conduct gastroscopy, X-ray or CT examination of the scapular region, to understand the cause of the disease, and to give symptomatic treatment under the guidance of a doctor. Patients who often have stomach pain should have a light, soft and easily digestible diet, and avoid the intake of spicy and irritating food.
