It’s serious, and if my analysis is correct, this patient is at least not cervical cervical, much less recommended for conservative treatment! Cervical spine problems have become very common, and as a person living in today’s society, people without cervical spine problems are simply the benchmark of the people! Among such patients, I believe there are not a few who have numbness in their arms due to cervical spine lesions. These patients can have numbness in their hands when they are physically tired, when they sleep, when they have mood swings, or even when they have numbness for no apparent reason! I believe you have experienced numbness in your fingers and upper arms. At first, the attacks may only be occasional and last for a short period of time, but after a period of time, they will gradually become more frequent, and each time the numbness becomes longer, and you may even wake up during sleep because of the strong numbness. Case study! I have such a patient in my department now. She is 48 years old, female, complaining of shoulder and neck stiffness, pain, and numbness in her right hand, and she wakes up every night with numbness, and her condition lasts for a long time, with shoulder and neck discomfort for more than 10 years and hand numbness for 6 years. It was accompanied by periarthritis in the right shoulder, and she could not lift her right arm. On the film she took, it showed straightening of the cervical curvature, ligaments with hyperplasia, calcification, degenerative changes, and joint disorders. Some people are more confused, shouldn’t cervical spondylosis cause pain at the back of the neck, so why would it cause hand numbness? In fact, there are many types of cervical spondylosis, including neurogenic cervical spondylosis, spinal cord cervical spondylosis, sympathetic cervical spondylosis and vertebral artery cervical spondylosis. Among them, neurogenic cervical spondylosis is the most common, which is caused by nerve root compression or nerve root canal stenosis after disc herniation, resulting in nerve root compression and irritation. This type is most common in the lower cervical vertebrae, i.e., the 4th to 7th cervical vertebrae, and most of them can develop over the age of 30, with chronic and recurrent attacks. Cervical spondylosis presenting with hand numbness is generally seen in the nerve root type and sympathetic type. The nerve roots entering the upper extremity are mainly compressed by the protruding intervertebral discs of the neck with proliferated bone or calcified ligaments and vertebrae with altered curvature, thus leading to a weakened conduction of the nerves and causing obvious symptoms of hand numbness. Since the nerve is affected, excitation disorder occurs, so the effect of conservative treatment alone is not obvious. Minimally invasive surgery is recommended to restore the disordered excited nerve to normal through neuromodulation, otherwise the patient’s symptoms will not disappear, and may even get worse and recur. After treatment, such patients need to pay attention to daily protection: adjust the sleeping posture and pillow, try to sleep on a hard bed, the pillow and shoulder level; correct the long-term low head position in the work, the head can be tilted and stretched from time to time; enhance the exercise of the neck muscles, in addition, also pay attention to the neck warmth, to prevent cold. Once there is a significant hand numbness, a need for timely medical treatment, to avoid nerve root pressure will be serious later amputation.
