Cervical spinal stenosis is a comprehensive type of cervical spine degeneration, a form of cervical spine degeneration in its final stage, including cervical disc herniation, cervical spine osteophytes, hypertrophy of the ligamentum flavum, and even small articular synapses, and congenital cervical spinal stenosis. Such diseases, which usually compress the spinal cord and even the nerves, can certainly cause headaches. Firstly, by directly compressing the nerves assigned by the cervical vertebrae, such as the large occipital nerve and the small occipital nerve assigned by the 1st and 2nd cervical vertebrae, which directly innervate the back of the head and the sensation to the top of the brain, it causes severe headache. In addition to this, some spinal cord compression can reflexly cause headache and dizziness. It is important to promptly diagnose the headache of cervical spinal stenosis compression. However, it should be reminded that although cervical spinal stenosis can cause headache, there are many causes of headache, so you should not treat the headache as cervical spondylosis, but must make a differential diagnosis. Some headaches may be caused by craniosynostosis, so the treatment of headaches should not be delayed because of cervical spondylosis. Because it is not rare for headaches to be caused in cervical spondylosis, we need to be reminded of this.
