A vague pain under the right side of the chest should first be examined with a color ultrasound of the abdomen as well as a chest radiograph. Because the most common disease is a disease of the liver, it will show pain in the right side of the rib cage area and also symptoms of the digestive tract. Viral hepatitis is very common, and as the disease evolves, post-viral hepatitis cirrhosis is likely to occur. Patients may experience pain in the right quadrant of the rib cage, accompanied by acid reflux and belching, and the symptoms may be aggravated by eating fried foods and overeating. For mild pain, oral aminoglutethimide tablets can be used for treatment. For severe pain, enhanced CT examinations are required if necessary, and systemic intravenous chemotherapy can be used to relieve the patient’s pain and discomfort if the condition permits. Local soft tissue contusions or strains can also be painful and can be treated with oral broad-spectrum celecoxib or diclofenac tablets, and care should be taken not to strain during treatment.
