1.What is cervical spondylosis? Cervical spondylosis is a series of symptoms caused by degenerative changes in the cervical spine and the joints, joint capsule, ligaments and intervertebral discs between them, resulting in cervical instability and pathological changes such as osteophytes, ligament and joint capsule hypertrophy or calcification, which stimulate or compress the cervical nerve roots, vertebral artery, spinal cord and sympathetic nerve, also known as cervical degenerative osteoarthrosis and cervical spine syndrome. 2, cervical spondylosis prevalent population? The disease occurs mostly in the middle-aged and elderly, but due to the popularity of computers and cell phones, the onset of cervical spondylosis tends to be younger due to the “low-heads” and “gamers”. People who work for a long time such as accountants, drafting workers, office copywriters, etc. are prone to clinical symptoms. 3.What are the symptoms of cervical spondylosis? There are various clinical manifestations of cervical spondylosis. According to different clinical manifestations, cervical spondylosis is divided into five types: cervical cervical spondylosis, neurogenic cervical spondylosis, vertebral artery cervical spondylosis, spinal cord cervical spondylosis, and sympathetic cervical spondylosis. Cervical cervical spondylosis: It is manifested by repeatedly falling off the pillow. If you have repeatedly fallen off the pillow, you need to pay attention to the fact that you may have cervical spondylosis and need to go to the hospital for consultation and medical treatment. Neurogenic cervical spondylosis: Discomfort in the neck and shoulders accompanied by pain or numbness in the upper limbs, often spreading to the fingers; soreness and sleepiness in the neck, a feeling of heavy pressure in the back; restricted cervical movement, skewed head and neck; cervical muscle spasm; chills and fever in the upper limbs, flushing, whitening, cyanosis or swelling of the skin, deformation, lack of luster and easy brittleness of the nails. Vertebral artery type cervical spondylosis: manifests as vertigo or headache, usually during the turning of the head. It is episodic and intermittent, and vertigo may be rotational, floating, shaking or lower limbs are weak and unstable standing, with sensations such as ground tilt or ground movement; numbness of the face, perioral area, tongue, limbs or half of the body, pins and needles sensation, ants walking sensation, etc. may occur. Spinal cord type cervical spondylosis: manifests as first lower limb symptoms such as unilateral or bilateral lower limb numbness, sleepiness and heaviness, followed by difficulty walking, unstable walking, and a feeling of stepping on cotton. Sympathetic cervical spondylosis: It is manifested in two types. Sympathetic excitatory type: headache, dizziness, enlarged eye fissures, blurred vision, dilated pupils, accelerated heart rate, arrhythmia, precordial pain, elevated blood pressure, vasospasm of the limbs, chilled limbs, reduced local temperature, excessive sweating; tinnitus and other symptoms. Vagal excitation type: headache, dizziness, droopy eyelids, tearing, nasal congestion, slower heart rate, decreased blood pressure, increased gastrointestinal motility or belching. In some cases, cervical spondylosis may be considered as a factor when the heart panic and palpitations are not detected in cardiology and other departments.
