To the right of the fossa of the heart are the lungs, liver, gallbladder, and part of the stomach, so if you are experiencing pain and discomfort to the right of the fossa of the heart, you need to consider the possibility of lesions in these areas. However, angina pectoris can radiate to this part of the body, so cardiac problems cannot be ruled out. First of all, we need to do an electrocardiogram to see if there is any heart problem, the common situation is coronary heart disease, angina pectoris, myocardial infarction, or symptoms caused by vegetative nerve dysfunction; if we exclude the heart problem, we can do a liver, gallbladder, pancreas and spleen ultrasound and liver function test to see if there is any cholecystitis or gallbladder stones, as well as hepatitis, cirrhosis and other conditions; if we exclude the problems of liver and gallbladder, we can take a chest radiograph to exclude the possibility of lung disease. If the liver and gallbladder problems are excluded, a chest X-ray can be taken to exclude lung and pleural diseases; if gastritis, gastric ulcer or duodenal ulcer are considered, a gastroscopy can be considered to clarify the situation.
