Back pain after turning head may be caused by fasciitis of the back, or it may be caused by cervical spondylosis. 1. Fasciitis: the position of the back is covered by abundant myofascial tissues, and prolonged stooping and hunching or cold stimulation may lead to aseptic inflammation of the myofascia of the back, resulting in obstruction of local blood circulation and accumulation of inflammatory metabolites. Acute fascial tears in the neck and shoulders when turning the head can also cause pain in the back. 2. Cervical spondylosis: when the cervical spine has degenerative changes, firstly, there will be compensation for the soft tissues of the neck and shoulder, and secondly, due to the dehydration of the intervertebral discs, there will be a certain amount of compression of the nerve tissue. When you turn your head, due to the rotational effect of the upper and lower vertebral bodies, the myofascia is further strained, resulting in more obvious compression of the intervertebral disc, both of which will cause the above symptoms. Back pain after turning the head may also be related to trauma, cold, etc., need to be combined with the characteristics of the medical history, the corresponding test results to make an accurate judgment, it is recommended to clarify the cause of the disease under the guidance of a doctor.
