1.Difficulty in swallowing Some people start to feel itching and foreign body sensation in the throat, and then feel difficulty in swallowing, with intermittent episodes, sometimes light and sometimes heavy. Patients are sometimes suspected to have esophageal cancer, but gastroscopy is normal. Later, CT scan may show cervical spondylosis. 2, hypertension hypertension cervical spondylosis can cause an increase or decrease in blood pressure, but the former is more common, called cervical hypertension, which is related to the stimulation of sympathetic nerves by bone. Patients are often accompanied by neck pain, tightness, upper limb numbness and other typical performance. 3. Breast pain is caused by the compression of the nerve roots of the 6th and 7th cervical vertebrae by the hyperplastic bone. It starts with pain in one breast or pectoralis major muscle, intermittent vague pain or paroxysmal stabbing pain, which is most obvious when turning the head to one side, and sometimes the pain is unbearable. This pain is sometimes misdiagnosed as angina pectoris or pleurisy. 4. Lower limb paralysis or defecation disorder is caused by stimulation of the lateral bundle of the spinal cord. Patients have numbness, painful weakness, and limpness in the upper extremities, and most neck symptoms are mild and easily masked. Some patients may suffer from frequent urination, urinary urgency, incontinence or urinary and fecal incontinence. 5. Visual impairment cervical spondylosis may also manifest as decreased vision, intermittent blurred vision, distention and pain in one or both eyes, photophobia, tearing and narrowing of visual field. This visual impairment is related to the plant nerve dysfunction caused by cervical spondylosis. 6, the sudden fall is caused by the compression of the vertebral artery by the hyperplastic bone, which is easily misdiagnosed as cerebral arteriosclerosis or cerebellar disorders. The body often loses support and falls suddenly when the head is suddenly twisted during walking, and then wakes up and stands up after the fall due to the change of the neck position.
