Is headache caused by cervical spondylosis?

Headache may be caused by cervical spondylosis, when the physiological curvature of the cervical spine becomes straight and compresses the vertebral artery, causing insufficient blood supply and oxygen supply to the brain. However, it should be noted that there are many other causes that can also cause headaches, such as hypertension, diabetes, lumbar disc herniation, etc. In addition, headaches can also be caused when mental stress is high, emotional excitement, and insufficient rest.
