Head backward cervical spine, spinal pain, may be due to the following causes: First, may be due to cervical spine related injury caused by, for example, the patient’s cervical spine suffered a direct violent blow, or do strenuous activities, this may cause soft tissue damage around the cervical spine, or there is a cervical fracture, dislocation. At this time, if the patient continues to do the head backward activities, it is possible to stimulate the injury site, which in turn causes obvious pain around the cervical spine. Second, this situation may be caused by the misalignment of the small joints of the cervical spine, for example, the patient has some long-term bad posture, resulting in the small joints of the cervical spine have some relative relationship disorder, which will lead to the patient to do head backward movement, stimulate the cervical spine with misaligned parts, and then produce obvious pain. Third, this condition may be caused by degenerative changes in the cervical spine, such as long-term sitting and standing with the head down, cold in the neck or some overuse of the neck, which may cause a series of lesions such as osteophytes, ligamentous hypertrophy, calcification and disc protrusion in the cervical spine, leading to the above symptoms. Fourth, this condition may also be caused by typical cervical spondylosis.
