Cervicogenic headache is characterized by repeated dull or aching pain in the occipital area, top of the head, temples, forehead or around the orbits, accompanied by pain in the upper part of the neck with a feeling of stiffness. In particular, headache may be triggered or aggravated by head and neck movement. When examined, there are obvious pressure points in the neck and occipital area, and pressure may cause headache symptoms to worsen. Why do neck disorders cause headaches? The harm caused by cervical spondylosis is enormous, but it often does not attract enough attention. There are many causes of headaches, but nearly 80% of headaches in pain clinics are closely related to cervical spondylosis, which is called “cervicogenic headache” because the neck is the emitting point of the nerves in the head and the bridge to the blood supply to the heart and brain. The cervical nerves 1–4 are 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 sensation in the occipital, parietal, frontal, and facial areas. It is believed that cervicogenic headaches are caused by compression and immune inflammatory stimulation of the cervical nerves due to disc herniation or other causes, as well as by small joint disease and muscle lesions of the cervical spine. It is important to note that there are many causes of headache, so the diagnosis of cervicogenic headache must exclude headaches caused by eye, ear, and nose disorders, intracranial tumors and vascular malformations, pterygopalatine neuralgia, cavernous sinus syndrome, trigeminal neuralgia, and migraine. These headaches are often very similar to cervicogenic headaches and can be difficult to differentiate, so an experienced specialist is needed to make the diagnosis. What are the symptoms of cervicogenic headache? Cervicogenic headache is triggered by the neck. The symptoms of cervicogenic headache are as follows: 1) the headache is usually on one side; 2) the pain starts in the neck and spreads to other parts of the head; 3) the time of attack or aggravation varies from several hours to several weeks; 4) the headache is paroxysmal at the beginning of the attack, but later it becomes chronic fluctuating headache; 5) the nature of the pain is mostly throbbing, stabbing, swelling and burning; 6) the headache is often accompanied by tinnitus, vertigo, hearing impairment, nausea, vomiting and other symptoms; 7) the headache is often accompanied by the symptoms of cervicogenic headache. 7. Gait instability can be seen during headache attacks; 8. There are many excitation points for headache, such as the cephalicus, trapezius and sternocleidomastoid muscles. The cause of cervicogenic headache can be divided into two categories: physiological and organic. Physiological headache is mostly caused by long-term low head work, and in a few cases, the neck is in an improper position. In contrast, organic headache is mostly caused by cervical spine hyperplasia, and in a few cases, it is seen in atlantoaxial deformity or atlantoaxial subluxation. Compared with physiological headache, organic headache is mostly accompanied by numbness and pain in upper limbs. However, because the focal area of headache is hidden and not easy to find, cervicogenic headache is often underdiagnosed or misdiagnosed, which causes patients to turn around and seek for medical treatment, but they cannot get reasonable treatment and cannot be cured for a long time. At present, home computers are very popular, and many people, especially young adults, spend a long time at the computer with their heads down working, studying or playing, and often feel neck pain, stiffness, and even headache, and if this phenomenon occurs, you should be alert to the possibility of cervicogenic headache. According to director Xu Jinming, in recent years, the number of patients with cervicogenic headache who come to the neurology department is increasing, and they are mainly young adults. Long-time low head work can cause abnormal tension in the fascia of the neck, making local blood circulation is impaired, muscle stiffness, long-term continue to make fascia contracture, the formation of chronic aseptic inflammation, intervertebral disc degeneration protrusion, compression and stimulation of nerves, thus triggering a series of symptoms such as headache, neck pain and stiffness. Office white-collar workers, do not always stay by the computer, not to mention a long time in a low state. Generally stay at the computer for about 1 hour, we should stand up to move 10 to 15 minutes, and try to lift the head and massage the neck with your hands for a few minutes to improve local blood circulation and relieve the tension in the neck. Pay more attention to the posture of the head and neck when working for a long time, about two hours of continuous work should do a cervical exercise to move the head and neck up and down. In addition, choose a suitable pillow, maintain the correct sleep posture for the relief of headaches caused by excessive stress is also very helpful. Many families do not pay attention to the role played by the pillow on sleep, and the market sales of pillows without size, in fact, the shape of the pillow and the size of the person’s sleep quality has a great impact, a good pillow should be in the human head pillow up after the cervical spine to maintain the normal physiological curvature, so that the cervical spine through the night’s rest fatigue to get full relief. Therefore, the usual cervical spine is not good for the public should choose a pillow suitable for the natural curvature of the neck at the spine, so that the neck has a reliable support, the height and fist about the pillow, the width should not be too large.
