Cervical spine pain and head pain with dizziness and nausea symptoms are commonly caused by cervical spondylosis causing cerebral blood supply insufficiency, which leads to the above symptoms. Among cervical spondylosis, sensorineural cervical spondylosis and vertebral artery cervical spondylosis, which can have a single attack or a mixed attack, can both cause symptoms of cerebral insufficiency of blood supply. Both types of cervical spondylosis are caused by a herniated cervical intervertebral disc compressing the hook vertebral joint and causing hyperplasia of the hook vertebral joint, and the vertebral artery traveling through the transverse foramen is compressed by both the cervical intervertebral disc and the hook vertebral joint, resulting in spasm and stenosis, causing cerebral blood supply insufficiency, resulting in head pain and nausea with dizziness. This symptom should also be distinguished from migraine, which can also cause headache, dizziness and nausea, but the attack site is on one side of the brain instead of the whole head.
