Cervical spondylosis is a disease in which the cervical spinal canal or intervertebral foramen is deformed or narrowed due to “degenerative disease of the cervical spine”, which irritates and compresses the crestal medulla and nerve roots in the neck and causes the corresponding clinical symptoms. “Cervical spondylosis” is divided into neurogenic, crestal medullary, sympathetic and vertebral artery types. The nerve root type is the most common type of cervical spondylosis, accounting for about 60% to 70% of cervical spondylosis, mainly manifesting as radiating pain or numbness in the arm, and most of them can be cured conservatively. 2, most of the crestal medullary type is related to the narrow development of the spinal canal, with symptoms of crestal medullary compression, most of which require surgery, and the clinical manifestations are mainly three points: (1) unilateral or bilateral lower limbs numbness, a feeling of heaviness, followed by gradual difficulty in walking. (2) Weakness of the hands and inflexibility of fine movements. (3) Some patients have bladder and rectal dysfunction, such as difficulty in urination, urinary frequency and urgency, etc. (3) The sympathetic nerve type has diverse symptoms involving many parts of the body, such as dry eyes, astringent eyes, swollen eyes, dizziness, headache, tight scalp, tinnitus, itchy throat, foreign body sensation, tingling in the mouth, nausea and vomiting, abdominal distension, panic, chest tightness, shortness of breath, breathlessness, coolness or fever in a certain limb, excessive sweating or no sweating. 4. Vertebral artery type is very rare. Neck and shoulder pain, dizziness and headache, numbness of the upper limbs, muscle atrophy, spastic paralysis of the lower limbs, difficulty walking, and even paralysis are common manifestations of cervical spondylosis. If the above symptoms are found in the body, it is recommended to go to the hospital as soon as possible.
