The pain in the back of the head may be caused by high blood pressure, tension-type headache, brain tumor and so on. 1. High blood pressure: High blood pressure may also cause pain in the back of the head, because when blood pressure is elevated, the cerebral perfusion blood flow in the brain will be relatively high, and the vascular regulation function of the brain will be abnormal, resulting in pain in the occipital region, temples, forehead and other places. 2. Tension-type headache: this disease is caused by head muscle or myofascial contraction or ischemia, the release of inflammatory mediators and other triggers, but also depression, anxiety and other factors. It is characterized by persistent head discomfort, such as throbbing pain, throbbing pain, pulling pain, etc., and the pain occurs in the occipital area and temples on both sides. 3. Brain tumor: Brain tumor may also cause pain in the back of the head, because the tumor in the brain may extrude the blood vessels near the back of the head, causing blood vessel blood circulation blockage or not smooth, resulting in hypoxia and ischemia of the brain tissue, and symptoms such as pain in the back of the head appear. If the symptoms are more serious, it is recommended to go to the hospital to find out the cause of the pain in the back of the head and then do the corresponding treatment.
