Pain on both sides of the back of the head may be related to trauma, or it may be caused by cervical spondylosis, posterior circulation ischemia and other reasons. 1. Trauma: If the two sides of the back of the head are accidentally hit or struck by an external force, resulting in trauma to the area, it may cause pain in the raised area on both sides of the back of the head, which may also be accompanied by localized bruising, edema and other symptoms. Sprains and contusions caused by over-exertion or incorrect posture may also cause pain. 2. Cervical spondylosis: If patients with this disease fail to pay attention to good daily care, and still maintain an incorrect posture for a long time, it is easy to lead to local vascular compression, resulting in insufficient blood supply to the vertebral basilar artery, which may cause pain on both sides of the back of the head, and can be accompanied by dizziness, numbness and weakness of the upper limbs and other manifestations. 3. Posterior circulation ischemia: usually due to cerebral atherosclerosis, cerebral embolism and other reasons, leading to the narrowing or embolism of the posterior circulation blood vessels in the brain, resulting in ischemia of the brain tissue in the area, which may cause pain in the back of the brain, and may be accompanied by dizziness, limb weakness and other symptoms. Pain on both sides of the back of the head may also be related to other factors, if the symptoms continue to be unrelieved, it should be taken seriously and go to a regular hospital as soon as possible, and after diagnosis, be guided by the doctor for treatment.
