Patients with cervical spondylosis who have headache and nausea can be relieved by the following methods: First, conservative treatment: bed rest as well as external fixation of the cervical brace can limit the activities of the cervical spine to avoid compression and stimulation of the vertebral artery, thus restoring the blood supply to the brain and relieving clinical symptoms such as headache and nausea. In addition, it can also be combined with massage, massage and local hot compress treatment, which can play a similar therapeutic effect. Second, surgical treatment: For severe vertebral artery stenosis, if the patient’s symptoms are heavy and cannot be relieved by conservative treatment, surgical treatment should be considered to enlarge the narrowed transverse foramen and relieve the compression of the vertebral artery, which can completely relieve the clinical symptoms such as headache and nausea. After surgery, patients need to cooperate with cervical braking and rehabilitation of neck muscles in the short term to consolidate the treatment effect and avoid recurrence of symptoms.
