Anatomical studies have found that the 1D4th cervical nerve is closely related to headache, and these nerves are interconnected to form the greater occipital nerve, the lesser occipital nerve and the greater auricular nerve, which conduct sensations in the occipital, parietal, frontal and facial areas. Etiology 1.Cervical disc degeneration and/or protrusion 2.Cervical small joint dysfunction 3.Cervical muscle strain Most patients suffer from trauma and poor work and life posture. Clinical manifestations 1. In the early stage, it is mostly discomfort in the occipital area, behind the ear and below the ear, and then gradually appears stuffiness or soreness until pain. The pain may extend to the forehead and the top of the temporal area. 2. Accompanying symptoms may include tinnitus, ear swelling, eye distention, head stuffiness, stiff neck discomfort, many patients may have nausea, vomiting, and in severe cases, mental discomfort and limb weakness. 3. The pain is chronic, sometimes light and sometimes heavy, and can be aggravated by cold, exertion and emotional excitement, and can be relieved after rest. As the disease progresses, it shows a tendency to gradually worsen. Signs 1) There is obvious pressure pain in the paracervical vertebrae below the ear and behind the mastoid process, and there may be pressure pain in the neck, the top of the temporal area and the neck. (2) Some patients may have local hyperalgesia, and some patients may have decreased sense of smell and taste on the affected side. (3) Pressure top test and head rest test may be positive Auxiliary examination 1.X-ray examination may show degenerative manifestations of cervical spine, such as loss of cervical physiological curvature, vertebral osteophytes, narrowing of intervertebral foramen, narrowing of intervertebral space, calcification of supraspinal ligament, etc. 2.CT examination can show changes such as osteophytes, spinal stenosis, disc bulge or protrusion. 3.Cervical MRI can show the changes of disc degeneration, herniated compression of dural sac or spinal cord, compression of cervical nerve root and narrowing of vertebral artery orifice, which is the preferred imaging method for diagnosing cervicogenic headache. 4.Exclude other causes of headache: ophthalmogenic, otogenic and rhinogenic headache, and exclude headache caused by intracranial tumor, vascular malformation, intracranial infection, etc. Diagnosis 1.Exclude other causes of headache; 2.Symptoms and signs must be consistent with cervical spine imaging changes; 3.Experimental cervical spine injection is effective Treatment 1.Rehab exercise, swimming, jogging, flying kites, playing badminton, etc. 2.Exercise in all aspects, not to do circle exercise, recommended to use the “rice exercise” 3.Calcium supplementation, such as drinking milk 4.Medication for young patients is muscle relaxant such as baclofen or Myrna with non-steroidal, and for elderly patients is nerve nutrition such as adenosine cobalamin plus vitamin B1 injection. 5.Nerve block cervical 2 paravertebral injection of anti-inflammatory and analgesic drugs, 0.26% lidocaine plus 10mg trimethoprim 10ml. 6.Severe symptoms can be treated in hospital, using CT-guided minimally invasive neurointerventional analgesia, that is, through The anterior epidural space is placed to give continuous anti-inflammatory and analgesic drugs to eliminate inflammation in the spinal canal, followed by the injection of collagenase to dissolve the intervertebral discs compressing the nerve roots. Other methods include intradiscal collagenase lysis, ozone intradiscal lysis, and cervical nerve disruption. With the rice character exercise: feet shoulder-width apart, arms crossed at the waist, the head drives the neck to do the activity of writing the “rice” character, in the order of strokes. Do 8 rotations in 8 directions and count 8 beats silently, one horizontal for 2 beats, one vertical for 2 beats, and the other 4 strokes for 1 beat. When doing the “rice exercise”, the movement should be comfortable, slow, soft, rhythmic, and the head swing to the most extreme point, and repeat this action 10 times. 2 times a day, 1 time each morning and evening, 2 weeks for a course of treatment. To relieve the neck muscle spasm has obvious effect.
