Headache is extremely common and is the most common disease in neurology clinics; it is also very complex and most patients cannot find a clear cause. However, there is a type of headache that is caused by cervical spondylosis, called cervicogenic headache. Since its symptoms are manifested in the head but the lesion is in the cervical spine, it is clinically hidden and has the characteristic of “striking the west with sound”, which is often unrecognized and easily misdiagnosed and mistreated. Cervicogenic headache is a clinical syndrome caused by lesions of the cervical spine and/or soft tissues of the neck, mainly headache, which is common in the occipital region of the head, but may also appear in the temporal region of the head or the brow bone of the forehead, accompanied by neck pain, vertigo and other symptoms of cervical spondylosis. Why do neck disorders cause headaches? Because the 1st-4th cervical nerves from the cervical spine are interconnected to form the occipital nerve, occipital nerve and auricular nerve, which conduct sensation in the occipital, parietal and temporal areas. In addition, since some muscles in the neck also start from the head and occiput, small joint diseases and muscle lesions can also be involved in the head and cause headaches. There are two characteristics of cervicogenic headache: one is that the headache is mostly located in the occipital, parietal and temporal regions of the head, and the other is that the attacks of headache are mostly related to the activities and strain of the neck. It is important to note that there are many causes of headache, therefore, the diagnosis of cervicogenic headache must exclude headache caused by eye, ear, nose and cranio-cerebral diseases, the symptoms of headache caused by these diseases are often very similar to those of cervicogenic headache, and it is difficult to differentiate them, so an experienced specialist is needed to make the diagnosis. After the diagnosis of cervicogenic headache is confirmed, treatment should focus on the lesion area of the neck to eliminate the local soft tissue inflammation and reduce the compression of the intervertebral discs in order to relieve the headache. The principle of treatment should be based on non-surgical treatment, including Chinese and Western medicine, traction and physical therapy, etc. Local acupoint closure or spinal adjustment manipulation in the diseased cervical spine can achieve immediate results.
