Hidden pain in the stomach and back pain at the same time may be related to diseases such as cholecystitis, gastroenteritis and angina pectoris. 1. Cholecystitis: Because gallbladder is also one of the digestive organs, when cholecystitis is in acute attack, the secretion of bile will be abnormal. If the patient eats greasy meat food at this time, without bile to help digestion, it may cause indigestion, which leads to hidden pain in the stomach. At the same time, the patient will also have severe colic pain in the right upper abdomen, and will radiate to the back of the right shoulder. 2. Gastroenteritis: If the gastrointestinal tract is inflamed due to unclean diet, bacterial infection and other reasons, when the stomach peristalsis is accelerated, the patient usually has clinical manifestations such as hidden pain in the stomach. If the diastolic movement of the intestinal tract involves the back, it can cause back pain. 3. Angina pectoris: when angina pectoris is in acute attack, it can also cause vague pain in the stomach and back pain at the same time. This is because the stomach is close to the heart, when the heart because of acute ischemia caused by angina pectoris acute attack, can involve the back and stomach blood vessels, so that the back and stomach due to insufficient blood supply and pain. It is recommended that patients who experience both stomach pain and back pain should go to the hospital for a detailed examination to clarify the cause of the disease and follow the doctor’s instructions for symptomatic treatment.
