Headache
Headache is a common symptom of Hepatitis B, especially in the first stage of the disease. If patients have had a headache for more than three days, it may be related to their liver problems. Headaches can also be caused by stress, fatigue, and other health problems like high blood pressure or diabetes.
The liver makes more blood vessels than it needs to support the growing infection for one with Hepatitis B. This can cause headaches due to increased pressure on the brain and surrounding tissues.
