Soreness and swelling of the cervical spine may be caused by chronic strain, falling pillow, cervical degenerative disease, congenital malformation of the cervical spine and other reasons. 1. Chronic strain injury: such as long time playing with the cell phone or working at the desk can lead to chronic strain injury of the neck muscles, resulting in soreness and swelling of the muscles around the cervical spine. 2. Pillow fall: mainly related to improper pillow height and sleeping posture, causing fatigue and spasm of the neck muscles, which is often manifested as soreness and swelling of the cervical vertebrae in the morning after waking up. 3. Degenerative cervical spine lesions: with the increase of age, the cervical spine structure gradually degenerates, which can cause disc herniation, osteophytes, etc., and the compression of the spinal cord or nerve roots can cause cervical spine soreness and pain, accompanied by pain and numbness of one or both upper limbs. 5.
