Cervical spine causes headache is very common in clinical practice, often clinically known as cervicogenic headache, the reasons are as follows: 1, sternocleidomastoid muscle this muscle above the attachment in the back of the ear, traditional Chinese medicine is called high bone, modern medicine is called the posterior mastoid, which is the muscle attachment point. When the neck muscles are tense, the sternocleidomastoid muscle spasm, will cause the muscle attached to the place that the posterior mastoid pain; 2, larger muscles such as trapezius, trapezius muscle attached to the head of the occipital part of the back. Often in the clinical encounter patients say that the occipital pain, because the trapezius muscle attachment site, that is, touch the occipital area can feel the bulge. The bulge extends outward, to both sides, is an upward line, there is a prong, along the bottom down, is the muscle attachment area, if the trapezius muscle tension, spasm, fatigue, injury, will lead to occipital pain; 3, cervical pain and neurological causes such as the head of the occipital part of the occipital nerve, go in the side of the head, go in the middle of the muscle, if the muscle spasm, tension, will compress the occipital nerve, will also occur occipital pain, but the pain most often on one side of the head, the occipital nerve, the occipital nerve, the occipital pain. But the pain is mostly on one side of the headache that is migraine. These are three common clinical headaches, there is the sternocleidomastoid muscle caused by pain, the trapezius muscle caused by pain, the neck myogenic caused by the occipital nerve compression to produce headaches. Each of the three headaches has its own characteristics and is treated slightly differently.
