How to Determine if a Headache is Caused by Cervical Spondylosis

Generally, methods such as assessing the location and nature of the headache, its relationship to neck movement, cervical spine X-ray examination, and cervical spine CT scan can be used to determine whether the condition is cervical spondylosis. The specific details are as follows:

1. Headache location: Headaches caused by cervical spondylosis typically concentrate in the occipital, vertex, or temporal regions and may sometimes radiate to the orbital or auricular areas. If the headache mainly occurs in the forehead or involves the entire head and is not significantly related to neck movement, the likelihood of cervical spondylosis being the cause is relatively low.

2. Headache nature: Headaches resulting from cervical spondylosis are mostly dull or aching in character, although they may sometimes present as sharp or throbbing pain. The intensity is generally moderate and rarely reaches a severe level. If the headache presents as pulsating or explosive severe pain, it is usually not caused by cervical spondylosis.

3. Relationship to neck movement: Headaches caused by cervical spondylosis are often closely related to neck movement. The headache may worsen or be triggered after prolonged periods of looking downward, looking upward, turning the head, or maintaining the same neck posture for an extended time. However, symptoms may improve with appropriate neck movement or rest.

4. Cervical spine X-ray examination: Cervical X-rays can clearly display the basic anatomical structures of the cervical spine, including the physiological curvature, vertebral body morphology, and intervertebral disc space width. Observing changes in these structures can help identify common signs of cervical spondylosis, such as osteophyte formation, straightening of the physiological curvature, or reverse lordosis.

5. Cervical spine CT examination: CT scans provide clearer visualization of detailed bony structures of the cervical spine and offer more accurate diagnosis of bony abnormalities such as posterior vertebral osteophytes and narrowed intervertebral foramina. CT provides cross-sectional images that help detect subtle bony changes that might be missed on X-ray imaging.

When experiencing headache symptoms, it is recommended to seek medical attention promptly. A physician can perform a thorough medical history review, physical examination, and necessary ancillary tests to establish a clear diagnosis and formulate an appropriate treatment plan.
