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 mild and sometimes severe. Patients are sometimes suspected of having esophageal cancer, but gastroscopy is normal and CT scan shows cervical spondylosis. Hypertension Cervical spondylosis can cause an increase or decrease in blood pressure, but the former is more common and is called cervical hypertension. This is associated with sympathetic nerve stimulation by the bone. Patients often present with typical manifestations such as head pain, tightness, and numbness in the upper extremities. Breast pain The hyperplasia is caused by compression of the nerve roots of the 6th and 7th cervical vertebrae by the hyperplastic bone. It starts with pain in one breast or the pectoralis major muscle, intermittent vague pain or paroxysmal stabbing pain, most pronounced when turning the head to one side, and sometimes the pain is unbearable. This pain is often misdiagnosed as angina pectoris or pleurisy. Lower extremity paralysis or defecation disorder The lateral bundle of the spinal cord is irritated. Patients have numbness, painful weakness and limpness in the limbs. Most of the symptoms in the neck are mild and easily masked, and some are accompanied by frequent urination, urgent urination, incomplete urination or urinary and fecal incontinence. Visual impairment Cervical spondylosis may also manifest as decreased vision, intermittent blurred vision, swelling and pain in one or both eyes, photophobia, lacrimation, and reduced visual field. This visual impairment is related to the vegetative nerve dysfunction caused by cervical spondylosis. Sudden fall Caused by compression of vertebral artery by proliferating bone, it is easily misdiagnosed as cerebral arteriosclerosis or cerebellar disease. It is often caused by loss of support when the body suddenly turns its head during walking and falls, and then wakes up and stands up after the fall because the position of the head changes.
