The severity of cervical spondylosis largely depends on the clinical symptoms of the patient. If the patient with cervical spondylosis experiences discomfort and stiffness in the neck, along with headaches, dizziness, nausea, vomiting, blurred vision, hearing loss, unsteady walking, a sensation of stepping on cotton, numbness and weakness in both upper limbs, and swelling pain, it indicates that the cervical spondylosis is very serious and has caused significant compression on the vertebral artery and spinal nerve roots. Such patients need to be actively treated, and if necessary, surgical treatment should be carried out, involving the removal of the intervertebral disc and decompressive surgery to expand the spinal canal.
