Cervical spondylosis often presents many false impressions that can easily lead patients to believe they are suffering from other diseases, thus delaying treatment. The following six common illusions accompany cervical spondylosis: 1. Hypertension: Cervical spondylosis can cause blood pressure to rise or fall, but the former is more common and is called cervical hypertension. This is related to bone stimulation of sympathetic nerves. Patients are often accompanied by typical manifestations such as neck pain, tightness and numbness in the upper limbs. This kind of hypertension caused by cervical spondylosis is easily confused with hypertension triggered by cardiovascular and cerebrovascular. 2. Visual impairment: Cervical spondylosis can also manifest as vision loss, intermittent blurred vision, eye distention, photophobia, tearing and narrowing of visual field. This visual impairment is related to autonomic nerve dysfunction caused by cervical spondylosis. This visual impairment caused by cervical spine can be easily confused with other eye diseases, such as glaucoma. 3. Breast pain: It is caused by the nerve roots of the 6th and 7th cervical vertebrae being compressed by the hyperplastic bone. It starts with pain in one breast or pectoralis major muscle, intermittent slight 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 often misdiagnosed as angina pectoris or pleurisy. 4. Difficulty in swallowing: Some patients start to feel itching and foreign body sensation in the pharynx, and then may feel difficulty in swallowing, with intermittent episodes, sometimes light and sometimes heavy. Patients are often suspected of having esophageal cancer, but gastroscopy is normal, and only after CT scan is cervical spondylosis revealed. 5. Lower limb paralysis or defecation disorder: This is caused by the stimulation of the lateral bundle of the spinal cord. Patients have numbness, pain and weakness in the upper limbs, trekking, and most of the symptoms in the neck are mild and easily concealed, and some of them are accompanied by frequent urination, urgent urination, incontinence or urinary and fecal incontinence. 6, sudden fall: This is caused by the compression of the vertebral artery by the hyperplastic bone, which is easily misdiagnosed as cerebral arteriosclerosis or cerebellar disorders. It is often sudden fall when the body loses support when the head is suddenly turned during walking. After the fall, the neck position changes and the person comes to his or her senses and stands up.
