According to statistics, nearly 150 million people in China suffer from cervical spondylosis. China Healthcare International Exchange Promotion Association cervical and lumbar disease prevention and treatment professional committee survey shows that 82% of the country’s elderly people over 60 years old suffer from cervical spondylosis, and the prevalence rate of people aged 50 to 60 is 71%. Moreover, cervical spondylosis is getting younger and younger, with the prevalence of cervical spondylosis among young adults aged 20 to 40 years old reaching 59.1%, and even teenagers are not “spared”. What is cervical spondylosis? It is a variety of symptoms and signs caused by degenerative changes in the cervical discs and their secondary changes that irritate or compress the adjacent tissues. Clinically, it is commonly caused by instability or loosening of vertebral segments, herniated or prolapsed nucleus pulposus, proliferation of bone spurs, hypertrophy of ligaments and secondary spinal stenosis, which stimulate or compress adjacent tissues such as nerve roots, spinal cord, vertebral artery and cervical sympathetic nerve, and cause a variety of symptoms and signs. Clinical symptoms: There are many causes of cervical spondylosis, and its clinical manifestations are diverse and complex, varying in severity. How can cervical spondylosis be detected early? The following are some common manifestations of cervical spondylosis, which can help you diagnose cervical spondylosis early and seek medical examination in time. If the following six conditions appear, you need to seek medical attention in time: 1. Neck and shoulder pain: This symptom is the most common symptom of cervical spondylosis, with a very high incidence, often accompanied by head, neck, shoulder, back and arm pain, neck stiffness and restricted movement. It can develop when stimulated by long-term ambulatory work, blowing cold air conditioner, strain and so on. 2, upper limb pain, numbness: pain can be radiated to the occipital and upper limbs, different nerves present different distribution areas, sometimes accompanied by numbness, weakness and other symptoms, manifested as a heavy feeling in the back of one shoulder, upper limb weakness, finger numbness, limb skin sensory loss, hand grip weakness, sometimes unconsciously grip objects to the ground. 3, walking instability: this is a heavier category of cervical spondylosis, usually after the spinal cord compression damage, typical performance is: lower limb weakness, walking instability, two feet numbness, walking like stepping on cotton feeling. In more severe cases, there is even loss of control of bowel movements and urination, sexual dysfunction, and even tetraplegia. Usually need to be distinguished from hypertension, hypoglycemia and other neuropathy. 4, neck popping: is also a common type of cervical spondylosis, mostly due to cervical small joint degeneration, hyperplasia caused by the usual tightness of the neck, “click” when the activity, the tightness can be relieved for a short time after the activity. 5.Headache and dizziness: some cervical spine patients have headache and dizziness, some feel that their houses are rotating, some have nausea and vomiting and are bedridden, and a few may have vertigo and sudden collapse. But often need to be distinguished from otoliths, Meniere’s disease, cerebral infarction and other diseases. 6, hypertension: the onset of some patients with hypertension is strongly correlated with the onset of cervical spondylosis, and may be related to cervical spondylosis when the effect of regular systemic drug treatment is not satisfactory.
