The back of the head pain occurs when the head is bowed for a long time, which may be caused by muscle spasm in the neck and mouth when the head is bowed for a long time, which can involve the neurovascular in the back of the head, and the patient can have pain in the back of the head. If the patient has cervical spondylosis, which is generally more likely to occur, including cervical curvature straightening and cervical disc herniation, cervical spine MRI should be checked for clear diagnosis if necessary. If the patient looks down at the cell phone, plays computer for a long time, or works at a desk for a long time, it is easy to cause muscle spasm in the neck, and the patient is also prone to the above symptoms. Intracranial organic lesions, mainly seen in the posterior cranial fossa, such as brain tumor patients can appear, should be ruled out, and cranial MRI should be checked for a clear diagnosis. Prolonged head bowing may cause impaired blood supply to the brain, causing cerebral ischemia and hypoxia, and headache may also occur when there is severe hypoxia, and even dizziness may occur.
