Hidden pain in the liver area during the recovery period of hepatitis B may be caused by many reasons, the common ones are dietary factors, disease progression, medication factors and so on. 1. Dietary factors: if patients consume high-oil and high-fat food for a long time and abuse alcohol, it will lead to liver cell lesions or even acute hepatic necrosis, resulting in vague pain in the liver area. 2. Disease progression: patients may also have sudden disease progression, such as liver edema and liver enlargement, etc. Edema or enlarged liver tissue will stimulate the liver peritoneum, resulting in vague pain in the liver area. 3.

Hidden pain in the liver area during the recovery period of hepatitis B may have a variety of reasons, and it is recommended that the patient consult a doctor as soon as possible to find out the cause of the disease and treat it as soon as possible.
