What is the dull pain in the left stomach

It shows dull pain in the stomach, mainly in the left upper abdomen, mostly caused by gastritis, gastric ulcer or duodenal ulcer, and closely related to pain caused by stomach spasm. If you don't pay attention to regular diet, overeating or taking drugs that stimulate gastric mucosa greatly, it will cause increased gastric acid secretion, gastric mucosa damage and stomach spasmodic pain, which needs to be improved by acid-inhibiting stomach protection drugs and gastrointestinal antispasmodic drugs, and closely observe whether there are nausea, vomiting, acid reflux and other manifestations. If there is reflux, heartburn and chest pain, etc., and reflux esophagitis is closely related, after gastroscopy can understand the specific conditions of the lesion, repeated attacks also need to check whether there is Helicobacter pylori infection.
