Vomiting and dizziness are not associated with cervical spondylosis in most patients. The main clinical diagnosis of cervical spondylosis is the presence of nerve compression, such as nerve root type compression and spinal cord compression before cervical spondylosis is diagnosed. Symptoms of sympathetic nerve compression may be present with neck muscle pain, causing head discomfort or dizziness, which is generally less common. Cervical spondylosis causes headache and dizziness mainly due to cervical instability, such as vertebral misalignment can occur when lowering or tilting the head, causing dizziness. Only about 5% of patients with dizziness and vomiting have a direct correlation with cervical spondylosis, and most of them have somatic symptoms or neurological disorders, such as vestibular function problems, otoliths, etc. If dizziness and vomiting are encountered, symptomatic treatment can be given after excluding neurological diseases.
