Clinical statistics in recent years show that the prevalence of cervical spondylosis is increasing year by year, with about 7-10%. In this way, the number of cervical spondylosis patients in China exceeds 100 million. Some studies have even shown that the incidence of cervical spondylosis has surpassed that of diabetes, posing a serious threat to people’s health. So what exactly is cervical spondylosis? What are the symptoms of cervical spondylosis? Look down and see if you are one of them. Cervical spondylosis refers to degenerative changes in the cervical disc and its secondary pathological changes including changes in the physiological curve of the cervical spine and degenerative changes in the joints, ligaments and other tissues that stimulate or compress the cervical nerve roots, spinal cord, vertebral artery or sympathetic nerves in the neck and other tissues, resulting in a series of symptomatic manifestations in patients. It is mainly caused by wind and cold in the neck, trauma, or due to aging and strain of the cervical spine, such as improper sleep posture, poor posture at work or maintaining a posture for a long time. There are five main types of cervical spondylosis: cervical cervical spondylosis, neurogenic cervical spondylosis, spinal cord cervical spondylosis, sympathetic cervical spondylosis and vertebral artery cervical spondylosis. The reason for explaining the subtypes is that different types of cervical spondylosis have different symptoms. Cervical cervical spondylosis, the lightest and earliest form of cervical spondylosis, is mainly characterized by symptoms in the neck. If you often have soreness and swelling in your neck, shoulders or inner scapular muscles (that is, the middle of your back), which is especially obvious in the morning after waking up, or if you repeatedly drop your pillow, this is often an early manifestation of cervical spondylosis. These manifestations are actually early warning signals from your body, reminding you that your neck has been overused during this period of time (working at a desk for too long or using a cell phone or computer too much). The symptoms of cervical cervical spondylosis are relatively mild and can be easily ignored by patients because they can be relieved naturally, which may aggravate the condition with repeated attacks. Cervical spondylosis of the nerve root type is the most prevalent cervical spondylosis, accounting for about 60-70% of all cervical spondylosis. Since cervical spondylosis is caused by the stimulation of nerve roots, the typical symptoms of this type of cervical spondylosis are pain in the neck and shoulder, and a discharge-like pain or numbness in one arm. In the early stage of neurogenic cervical spondylosis, the main manifestation is pain and numbness in the neck, and in the late stage, there may be a feeling of heaviness in the upper limbs on the affected side, loss of grip strength, and sometimes weakness such as falling objects, and even muscle atrophy. Spinal cervical spondylosis, the most serious and dangerous cervical spondylosis, is a condition in which lesions in the cervical spine lead to compression of the spinal cord and symptoms such as inflammation and edema. It is often manifested as follows: 1. weakness of both hands, such as holding things unstably and falling easily; 2. inflexible hand movements and poor completion of fine movements, for example, it used to be easy to hold chopsticks and clip things, but now it is impossible to clip peanut rice and vegetables, so you can only use your hands; some patients’ writing has become crooked and their fonts have changed; 3. some patients have the feeling of walking unsteadily, like stepping on cotton, one foot deep and one foot shallow; some patients walk unsteadily. Some patients can’t walk in a straight line, and some patients have numbness and heaviness in the lower limbs. 4. Abnormal sensation in the trunk, the patient’s chest, abdomen or both lower limbs will have a binding feeling like being bound by a belt. Once these conditions appear, it means that cervical spondylosis has reached a more serious level. In sympathetic cervical spondylosis, the patient may experience dizziness, headache, nausea and vomiting due to degeneration of the cervical spine or stimulation of the sympathetic nerves. However, when these symptoms occur, the first reaction of patients is mostly to wonder, “Could I have a cerebrovascular problem?” Often, this atypical manifestation may also be caused by cervical spondylosis. Therefore, once this happens, it is important to go to the hospital in time to rule out whether these symptoms are caused by cervical spondylosis. In vertebral artery type cervical spondylosis, patients also have dizziness as the main manifestation, but it is often episodic and can even appear as a sudden fall, which is caused by insufficient blood supply to the brain when segmental instability and narrowing of the vertebral space occurs in the cervical spine, resulting in distortion and compression of the vertebral artery.
