The causes of vague pain in the liver area without abnormal ultrasound may be chronic liver disease, alcoholic hepatitis, diseases of the gallbladder, and the use of drugs. 1. Chronic liver: in the early stage of the disease, ultrasound may not be abnormal, but it may cause pain in the liver area. 2. Alcoholic hepatitis: The lesion of the liver is caused by long-term alcohol consumption, which may also lead to pain in the liver area without abnormal changes on the ultrasound. 3. Gallbladder lesions: In cases of cholecystitis, pain may be caused in the liver area although there may be no abnormality. Sometimes it may involve the right shoulder or possibly the back. 4. Taking medication: For example, anti-tuberculosis drugs such as pyrazinamide can cause discomfort in the liver area. It is advisable to see a medical professional for further examination. Define the cause of the disease. The next step in the treatment, so as not to delay the condition, usually pay attention to a light diet.
