Stomach and back pain is caused by diseases such as gastric ulcer, cholecystitis and pancreatitis. Gastric ulcers are one of the more common stomach disorders that occur due to the development of ulcerated surfaces in the mucous membrane of the stomach. The nature of pain in gastric ulcers is more intense, and when the site of the ulcer is on the back wall of the stomach, not only does it cause pain in the stomach, but it also causes pain in the back by pulling on the back. During the attack of cholecystitis, due to the stimulation of inflammation, it will cause invasion of the surrounding organs, many people during the illness of cholecystitis, accompanied by stomach pain, nausea, vomiting, back pain. Pancreatitis is a retro-membranous organ, and during an attack there will be radiating pain to the back, and in some cases to the shoulder area. The relative proximity of the pancreas to the stomach can cause stomach invasion, causing nausea, vomiting, and indigestion.
