Cervical cervical spondylosis is more common clinically, and the earliest manifestations are mainly neck symptoms, mainly neck pain and stiffness, which are often not given enough attention to make the disease worse by repeated attacks. When the cervical spine is in a certain posture for a long time, which makes the cervical spine bend for a long time, part of the intervertebral disc and its affiliated tissues gradually move in response to the displacement, stimulating the spinal cord or nerves and causing pain. The main discomfort is neck pain, swelling and stiffness, which often occurs in the morning after waking up or when waking up, it is difficult to lift the head, and patients often complain that they do not know what position to put their head and neck. About half of the patients have limited neck movement or forced position, and individual patients may have transient sensory abnormalities in the upper limbs. The pain increases with activity and can be relieved by rest. However, the performance varies due to different causes. The common typology and clinical manifestations are as follows: 1. 3.Vertebral artery type: often due to changes in head and neck position resulting in vertigo, nausea, headache and vision loss, some patients may be accompanied by nerve root irritation symptoms. 4. Sympathetic type: head symptoms: headache, head sinking, dizziness, occipital pain or posterior neck pain; facial symptoms: blurred vision, swelling and pain in the eye sockets, etc. Cardiac symptoms: panic, precordial pain and elevated blood pressure. 5. Esophageal type: less common clinically. This is mainly due to the protrusion of the bone spur at the front edge of the vertebral body to press the esophagus, causing difficulty in swallowing and other related clinical symptoms; or the stimulation or compression of the phrenic nerve by the bone superfluous makes the patient have difficulty in breathing, or the stimulation or compression of the recurrent laryngeal nerve causes hoarseness and other corresponding clinical manifestations.
