Cervical spondylosis, also known as cervical spine syndrome, is a general term for cervical osteoarthritis, proliferative cervicitis, cervical nerve root syndrome, and cervical disc prolapse, which is a disorder based on degenerative changes in the cervical spine, mainly due to strain and disc prolapse as a result of incorrect posture over a long period of time. Or due to osteophytes, ligament thickening, resulting in cervical spinal cord, nerve root or vertebral artery compression, a series of dysfunctional clinical syndrome. Clinically, cervical disc degeneration itself and a series of secondary pathological changes, such as vertebral joint instability, loosening, nucleus pulposus protrusion or prolapse, bone spur formation, ligamentous hypertrophy and secondary spinal stenosis, stimulate or compress the adjacent nerve roots, spinal cord, vertebral artery and cervical sympathetic nerve and other tissues, and cause a variety of symptoms and signs of the syndrome. Clinical manifestations: The symptoms of cervical spondylosis are very rich, diverse and complex, and most patients start with mild symptoms and gradually worsen. Patients often have one type of cervical spondylosis and combine with other types of cervical spondylosis, which is called mixed cervical spondylosis. Main symptoms: 1. Neck and shoulder pain can be radiated to the occipital area and upper limbs; 2. Heavy feeling on the back of one shoulder, weakness of the upper limbs: numbness of the fingers, loss of sensation of the skin of the limbs, weakness of holding things in the hands, and sometimes unconscious gripping of things to the ground. 3, its serious typical performance is: lower limb weakness, unstable walking, numbness of the second foot, walking like a feeling of stepping on cotton. 4. In the most serious cases, there is even loss of control of bowel movements and urination, sexual dysfunction, and even tetraplegia. 5.Often accompanied by head, neck, shoulder, back and arm pain: neck and neck stiffness, restricted movement. 6.Some are accompanied by dizziness, house rotation: heavy cases are accompanied by nausea and vomiting, bedridden, and a few may have vertigo and sudden collapse. 7.When cervical spondylosis involves sympathetic nerve, dizziness and headache may appear: blurred vision, swelling of both eyes, dryness, inability to open the second eye, tinnitus, ear blockage, loss of balance, tachycardia, panic, tight c feeling in the chest, and some even have symptoms such as gastrointestinal distention. There are also symptoms such as dysphagia and dysphonia. Most of the symptoms are mild at the beginning and are not taken seriously, most of them can recover on their own, sometimes light and sometimes heavy, and only when the symptoms continue to worsen and cannot be reversed and affect work and life do they get attention. If the disease is left untreated for a long time, it can cause psychological damage and produce symptoms such as insomnia, irritability, anger, anxiety and depression. Preventive measures: The prevention of cervical spondylosis is mainly for the types caused by incorrect personal posture. For hereditary or congenital cervical spondylosis can only slow down the development of the disease (such as dysplasia of the cervical spine structure: congenital small spinal canal is also the basis of the pathogenesis). Correct poor sitting posture and prohibit prolonged low head work. Generally sit for an hour or so to get up and move the neck and shoulders. Prevent ischemia and stiffness of the neck muscles. Neck health care has a positive effect on the prevention of cervical spondylosis to a certain extent. But to adhere to scientific and reasonable exercise, to prevent improper exercise leads to chronic strain injury of the neck. Protect the cervical spine and prevent trauma. Especially with drivers as the high-risk group.
