Right chest pain indicates right upper abdominal pain, possibly under the right costal margin. It is common for gallbladder stones to be combined with cholecystitis, or a disease of the stomach, such as gastritis. When gallbladder stones are present, there may be pain in the upper abdomen, vague pain, or even radiating pain in the lower back and shoulders, sometimes accompanied by nausea, vomiting, and anorexia. In chronic gastritis or gastric ulcer, the pain can also be manifested in the epigastric region under the raphe, sometimes accompanied by abdominal distension, acid reflux, belching, burping, and even sometimes black stools occur. The examination can start with a liver and gallbladder ultrasound, if stones are found inside the gallbladder and there is inflammation in the gallbladder wall, it means that it is caused by gallbladder stones. If there are no lesions in the gallbladder, a gastroscopy is needed, and either inflammatory changes or ulcerative changes can be found within the stomach, both of which can lead to a more accurate diagnosis.
