If frequent occurrences of the pillow, is often a precursor symptom of cervical spondylosis, should not be taken lightly. There are many reasons for the occurrence of the pillow, probably summarized in the following categories 1, pillow height discomfort can cause muscle fatigue in the back of the neck, ligaments and nerves due to excessive stretching easy to damage. 2, sleeping posture and poor work posture will make muscle tension for a long time and cause spasm, induced by the pillow. 3, long-term work in high pressure, anxiety, tension, irritability or depression, etc., the first will cause the neck and shoulder muscle spasm, compression of the muscle in the blood vessels, resulting in smaller and slower blood flow, muscle tissue does not get sufficient blood supply, produce too much metabolic products “lactic acid”, over time the neck and shoulder muscles become more and more stiff The neck and shoulder muscles become increasingly stiff, lack of elasticity, easy fatigue, and chronic pain, and sometimes even feel the wind and cold, which causes the pillow. 4, the neck and shoulder exposed to cold weather or because of electric fans, air conditioning cold air blowing directly, so that the local qi and blood stagnation, meridian paralysis, that will cause the disease. All of the above reasons, can lead to frequent pillow, so that the soft tissue damage to the neck, resulting in the cervical spine on both sides of the muscle imbalance, the neck dynamic system is damaged, resulting in the dynamic balance of the cervical spine imbalance. If it happens repeatedly, the vertebral body edge and intervertebral joints begin to proliferate and bone spurs are formed. Therefore, frequent drop pillow is seen clinically as a precursor symptom of cervical spondylosis. The cervical vertebrae may have curvature straightening and need to be corrected in the supine position with a pillow behind the neck. Massage therapy can relieve the spastic muscles, rectify the subluxation of the joints, improve the blood circulation of the muscles, repair the damaged tissues, loosen the adhesions, eliminate the edema, and finally restore the muscle strength of the posterior cervical muscle groups.
