Usually, people think that cervical spondylosis is nothing more than stiff neck, neck and shoulder pain, numbness of the fingers, etc., nothing great. I do not know the cervical spine on the skull under the trunk, neurovascular distribution of staggered and dense, is the human body nerves, cerebrovascular transportation hub, so it is the human body accidents in the area. Once the disease occurs, will inevitably affect the cardiovascular and cerebrovascular and central nervous system, resulting in a variety of cervicogenic diseases, can be said to affect the whole body. In fact, the symptoms of cervical spondylosis is also strange, there are some performance seems to be with the cervical spondylosis “wind horse and cattle are not related to”, or even confusing symptoms, often easy to be misdiagnosed, mistreated. 1, cervical visual impairment: some patients with cervical spondylosis first manifested as visual impairment, such as vision loss, intermittent blurring of vision, one eye or both eyes swelling and pain, photophobia, tearing, unequal pupil size, and even narrowing of the field of vision, sharp reduction in visual acuity, etc. The characteristic is that the eye symptoms are related to the cervical spondylosis, which is often misdiagnosed and mistreated. It is characterized by a clear relationship between eye symptoms and changes in neck posture, some of which are accompanied by symptoms of cervical spondylosis. Many patients feel that visual impairment occurs when the head and neck are in a particular bad posture for a long time. This kind of visual impairment is related to the ischemic damage of the visual center of the occipital lobe of the brain caused by autonomic dysfunction and insufficient blood supply of the vertebral basilar artery due to cervical spondylosis. 2. Cervical cerebrovascular disease: 26% of the nearly 1 million cerebrovascular patients in China each year are induced by cervical spondylosis. This is due to the vertebral-basilar artery pressure, resulting in insufficient blood supply to the brain, long-term maintenance of this state, there will be dizziness, numbness in the hands and feet, walking unsteady, and even the occurrence of cerebral thrombosis, cerebral infarction, and some patients can lead to hemiplegia. If timely treatment of cervical spondylosis, will not deteriorate into stroke hemiplegia and other serious consequences. 3, cervical neurasthenia: some teenagers due to cervical sympathetic nerve and vertebral basilar artery compression or stimulation, can cause headache, dizziness, palpitations, insomnia, sleeplessness, depression, memory loss and a series of neurasthenia symptoms. After cervical spondylosis, neurasthenia also disappears. 4, cervical vertigo: in changing posture position suddenly turn the head and neck can lead to the vertebral artery blood supply is insufficient, will suddenly feel the sky and earth, unsteady, and even fall. Usually, there are symptoms such as neck pain, headache, nausea and vomiting, tinnitus, hearing loss, blurred eyes, facial numbness, palpitations and so on. 5, cervical hypertension: some people suffer from “high blood pressure” for a long time, the final check is actually cervical spondylosis. Cervical spondylosis can cause blood pressure increase or decrease, but blood pressure increase is common. These patients are often accompanied by neck pain, tightness, numbness of the upper limbs and other symptoms of cervical spondylosis. Generally, the treatment of hypertension is ineffective, and when the symptoms of cervical spondylosis are controlled, the blood pressure decreases. This is related to the dysfunction of vertebral basilar artery blood supply and sympathetic nerve stimulation due to cervical spondylosis. Because cervical spondylosis and hypertension are both common in middle-aged and elderly people, there are more chances for the two to co-exist. 6, cervical angina: some people suffer from “angina”, and the general drug treatment is ineffective, should think of whether the cervical spondylosis caused by cervical angina. This is due to the domination of the diaphragm and pericardium of the cervical spine nerve root by the cervical vertebrae stimulation and compression, or cardiac sympathetic nerve stimulation. Patients may present with pain in the precordial region, chest tightness, premature beats and other arrhythmias and ST-segment changes on the electrocardiogram, which are easily mistaken for coronary artery disease. When pressing the cervical spine near the pressure area can induce pain, the head in a particular position and posture can make the symptoms worse, change the position is reduced, according to the cervical spondylosis treatment can receive obvious results. 7, cervical breast pain: mostly seen in middle-aged and old women with cervical spondylosis, starting to feel one side of the breast or pectoralis major muscle pain, intermittent pain or paroxysmal stabbing pain, turning the head to the side of the most pronounced, and sometimes the pain is intolerable. This pain is misdiagnosed as angina or pleurisy. It is caused by the compression of the nerve roots of the 6th and 7th cervical vertebrae by the hyperplastic bone. 8, cervical dysphagia: some patients start to feel itchy in the pharynx, have a foreign body sensation, and then feel dysphagia, intermittent episodes, sometimes light and sometimes heavy. A few have nausea, vomiting, hoarseness, dry cough, chest tightness. Many patients had been suspected of esophageal cancer, but gastroscopy was normal. X-ray examination of the cervical spine showed cervical spondylosis, and on lateral cervical spine radiographs, degenerative changes such as bony cumbersome bones protruding forward obviously were seen. This is due to the rapid osteophyte proliferation at the anterior margin of the cervical vertebrae, esophageal stenosis caused by the large bony outgrowths directly compressing the posterior wall of the esophagus, or esophageal spasms or excessive relaxation due to the phytoneurological dysfunction caused by the cervical spondylosis. It can also be caused by irritation of soft tissues around the esophagus due to the formation of bone spur. 9, cervicogenic gastropathy: the sympathetic nerves in the neck are stimulated by cervical spurs, degenerated intervertebral discs and the narrowed intervertebral space, the signals enter the sympathetic nerve network in the skull, pass into the hypothalamic vegetative nerve center, and then along the sympathetic or parasympathetic nerves and then to the internal organs, triggering the stomach to appear two phenomena, when the sympathetic nerve is excited, gastrointestinal secretion and peristalsis are inhibited, appearing dry mouth, anorexia, bloating discomfort, burping , abdominal distension and discomfort, hiccups and belching, epigastric vague pain, nausea and vomiting and other symptoms; when the parasympathetic nerve excitability increases, it can cause increased appetite, acid reflux and heartburn, belching, and pain during hunger, relieved by eating, and other symptoms similar to peptic ulcer. After curing cervical spondylosis, stomach symptoms disappear. 10, cervicogenic tics: mostly seen in children and adolescents, mainly long-term lying down, tilting the head, inclined head reading and writing, easy to cause cervical spondylosis, head tilted to one side, frequent twitching more than one phenomenon. Change bad habits, active treatment will soon suspend the twitching, and gradually recover. 11, cervical sudden collapse: often in standing or walking due to a sudden twisting of the head, the body lost support and sudden collapse, after falling to the ground due to changes in the position of the neck can quickly wake up and stand up, not accompanied by impaired consciousness, and no after-effects. This kind of patients may be accompanied by dizziness, headache, nausea, vomiting, sweating and other symptoms of vegetative nerve function disorders. This is due to the cervical vertebral hyperplasia of bone compression of the vertebral artery caused by the basilar artery blood supply obstacle, resulting in a momentary serious shortage of cerebral blood supply. 12, cervical paralysis of the lower limbs or defecation disorder: paralysis of the lower limbs or defecation disorder is caused by the irritation of the vertebral side bundle of the crest. Patients with upper limb numbness, pain and weakness, claudication, most of the neck symptoms are mild and easy to be concealed. Some are accompanied by frequent urination, urinary urgency, impure urination or incontinence. It can be seen, when some patients often appear headache, toothache, trigeminal neuralgia, vertigo, nausea, vomiting, insomnia, irritability or depression, vision and hearing impairment, taste and smell and skin sensory abnormalities, angina and other symptoms of prolonged treatment is ineffective, it may be worthwhile to check the cervical vertebrae, do not “headache, treat the symptoms of the head, feet”, because the lesions are very likely to be in the cervical spine. may be in the cervical spine.
