Jumping in the back of the head at night can be caused by cervical spondylosis, diseases of the posterior cranial fossa, mental tension and other factors. 1. Cervical spondylosis: osteophytes and herniated intervertebral discs in patients with cervical spondylosis can lead to pressure on the nerves innervating the back of the brain. Constant changes in body position during sleep may cause significant nerve compression, which in turn may cause throbbing in the back of the head. 2. Diseases of the posterior cranial fossa: when brain tumors and other lesions occur in the posterior cranial fossa, the throbbing of the hindbrain may occur after sleeping, and it is necessary to consult a doctor for a clear cranial MRI to clarify the lesions as early as possible. 3. Mental tension: When the pressure of life and study is great, mental tension is excessive, and the quality of sleep is poor, it can cause spasm of blood vessels in the brain and abnormal pulsation, and the symptom of throbbing in the back of the brain can appear after sleeping. The throbbing in the back of the head at night may also be caused by other reasons. Patients should consult a doctor in time, and under the guidance of specialists, active treatment will help to alleviate the uncomfortable symptoms as soon as possible.
