Intervertebral disc is a kind of discoid cartilaginous substance, and it is a natural shock absorber of human body, which can make us turn our head, straighten our waist and twist our body. The nucleus pulposus in the center of the intervertebral disc contains water and collagen fibers, so it is soft and elastic and can share the pressure and impact on the spine. The periphery of intervertebral disc is a tough ring, which can maintain the stability of nucleus pulposus.
People who work or drive in front of the computer for a long time always keep a posture, lack exercise and can't move their muscles. The coordination of cervical vertebrae is regulated by muscles. Bowing, raising and rotating are the results of coordination of different muscle tissues. If the muscle strength is too weak, the coordination of movements will be poor, which will lead to more uneven stress and damage to the intervertebral disc.
Unexpected symptoms of cervical spondylosis The symptoms caused by cervical spondylosis have a wide range, but the definition is simple. It is a pathological manifestation that the cervical spinal canal, intervertebral foramen and other important tissues are deformed or narrowed due to degeneration or pathological changes, which leads to the damage of surrounding important tissues such as spinal cord and neurovascular. The pathological changes caused by these physiological structures produce a series of secondary diseases, also known as cervical spondylosis. There are three main types of cervical spondylosis: 1. Myofascial symptoms. 2. Neurological symptoms. 3. Vascular symptoms.
Three symptom types of cervical spondylosis: myofascial symptoms? Most of these symptoms are caused by stressful life and lack of exercise, especially in the shoulder and neck position. ? Clinical features include: tightening the belt. Trigger point and involved pain. Local convulsion reaction. ? When a specific muscle has pain points, it often produces transitive pain in a specific area; In addition, you can see or feel the local twitch reaction of muscles when you use acupuncture or quickly press the muscle band.
Neurological symptoms? This type of cervical spondylosis is mostly caused by intervertebral disc degeneration, hyperosteogeny, loosening and dislocation of cervical joints and ligaments, which causes compression of cervical nerve roots and produces symptoms mainly in head, neck, shoulders, arms and fingers. ? People often say that the "sore" area on the back (in Taiwanese) is sour, so it is uncomfortable to move, and some even run along the shoulders and arms to the fingertips. ? Typical discomfort symptoms include upper limb ache, pain, numbness, sensory loss, muscle weakness, muscle atrophy and so on.
Vascular symptoms? Due to the degeneration of intervertebral disc, the intervertebral space of patients with cervical spondylosis is narrowed, the intervertebral distance is shorter than that of normal people, the vertebral artery is curved and the vascular cavity is narrowed. ? In addition to neck pain and discomfort, this type of cervical spondylosis is easy to degenerate into the following symptoms: radiation cerebral vasospasm, manifested as headache and dizziness; Cerebral ischemia, when the head turns to a certain position, it feels dizziness, nausea, vomiting, tinnitus, deafness, blurred vision and other symptoms, and even faints; Sudden numbness of limbs, abnormal sensation, weak grip or fainting, but without disturbance of consciousness, you can walk immediately after getting up.
Cervical spondylosis is a degenerative disease, which is a series of symptoms caused by degeneration, such as cervical hyperosteogeny (spur), disc herniation, ligament thickening, or compression of cervical spinal cord, cervical nerve and blood vessels. At first, it was recurrent neck and shoulder pain, reduced range of motion of the neck and frequent stiff neck; In severe cases, neurological symptoms such as hand numbness and hand trembling may occur. The cervical vertebra is the nerve transmission pathway that the brain directs the whole body's life activities. Once these nerves are affected, there will be manifestations of cervical spondylosis that ordinary people can't imagine.
Symptoms of cervical spondylosis with visual impairment include visual impairment, intermittent blurred vision, swelling of one or both eyes, tears and photophobia; In severe cases, the field of vision may even be narrowed. The occurrence of visual impairment is caused by ischemia and hypoxia of brain visual center caused by cervical spondylosis. Patients usually need to go to ophthalmology for medical treatment because of their illness, which delays their illness.
* * * Pain Cervical spondylosis can make patients feel intermittent dull pain or pain in one pectoralis major muscle, which is more obvious when the head turns to one side, and it is easy to be misdiagnosed as angina pectoris or pleurisy.
Dysphagia Many patients with cervical spondylosis will have itchy throat, foreign body sensation when swallowing, and then intermittent attacks. Dysphagia may be accompanied by symptoms such as nausea and vomiting. It is often mistaken for digestive system problems, but after esophagoscopy and gastroscopy, the results often show normal.
In severe cases, patients with cervical spondylosis accompanied by paralysis of lower limbs or difficulty in defecation will have numbness of limbs, sometimes accompanied by frequent urination, unclean urine or incontinence. However, because the symptoms are too far away from the neck, ignoring the above symptoms may also come from neck lesions.
Hypertensive cervical spondylosis leads to hypertension and is easily mistaken for other types of hypertension. Cervical spondylosis will be accompanied by neck pain, tension and numbness. These symptoms are related to excessive sympathetic nerve, and the blood pressure caused by sympathetic nerve will increase or decrease, which is called cervical hypertension.
