Cervical spondylitis is mainly due to three reasons: the first is due to the cervical spine part of the sustained fatigue to form the strain and produce inflammation, such as frequent head down, look at the case, look at the cell phone, look at the computer reading, read the newspaper for too long to lead to cervical vertebrae part of the sustained fatigue, and gradually form the strain to produce inflammation foci. This will produce stimulation of the peripheral nerves around, there will be pain as well as unfavorable activity symptoms. The second situation is due to the cervical spine has suffered trauma collision, which will form foci in the local. Even if the traumatic injury recovers, inflammation is easily formed in the local soft tissues, especially in the fascia, and it is easy for inflammation to build up when exposed to cold and exertion, which may aggravate the inflammation of the cervical spine. The third situation is that the cervical spine is cold. The cervical spine is easily exposed to the environment due to the lack of clothing to cover the cervical spine, especially when the head is bowed, which makes it easy to get cold. Especially in the heat of the day, blowing fans and air conditioning, as well as doors and windows of the convection will lead to the cervical spine cold, and the blood circulation slows down. The resulting inflammation cannot be metabolized in a timely and effective manner, and then inflammation builds up, resulting in inflammatory edema and cervical spine inflammation and pain.
