Cervical spondylosis can cause headache and dizziness, which is mostly seen in sympathetic cervical spondylosis as well as vertebral artery cervical spondylosis. Patients may also suffer from neck pain, palpitations and other symptoms. 1. Sympathetic type spondylosis: due to cervical vertebral osteophytes or cervical spine instability stimulate the sympathetic nerve endings around the cervical spine, leading to sympathetic nerve dysfunction, which will cause dizziness and headache symptoms. Patients may be accompanied by palpitations, chest tightness, arrhythmia and other manifestations, and may also be accompanied by dizziness, headache, memory loss and so on. 2. Vertebral artery-type cervical spondylosis: the protruding intervertebral disc compresses the vertebral artery, resulting in narrowing of the vertebral artery and insufficient blood supply to the brain tissue, thus causing headache and dizziness. The symptoms of headache and dizziness, it is recommended that patients go to the hospital in time for examination and diagnosis, to clarify the cause, and under the guidance of the doctor to carry out the corresponding treatment.
