Vague pain inside the right sternal rib cage can come from a variety of causes, involving diseases of the pleura, lung tissue, liver and biliary system, etc. First of all, inflammatory irritation from the rib cartilage can cause vague pain in the rib cartilage. Pleural diseases, such as infectious diseases, especially tuberculous pleurisy, can cause vague pain. In addition, the presence of lung diseases should be excluded, and the presence of diseases of the hepatobiliary system, especially cholecystitis, gallbladder stones or various acute and chronic hepatitis and fatty liver, may cause vague pain in the right upper abdomen, which may be similar to vague pain in the thoracic ribs, and pain in this area may occur because the localization of visceral pain is not too accurate. Preliminary examination can be performed, including chest imaging, such as X-ray or CT, and ultrasound examination of the hepatobiliary system is needed to initially rule out some diseases, and further treatment is needed if there are problems.
