If the patient has back pain from sleeping, it may be caused by the following reasons: 1. It may be caused by poor sleeping posture, many patients are used to prone position when sleeping, or make the trunk have a relatively large twist, at this time will often make the back muscles in a state of long-term tension, and then may produce muscle spasm, and then cause pain. 2. It may be caused by cold. The back of the back may be too hard or too soft, which may lead to pain. Too hard may make the back bone protrusion compression of the surrounding soft tissue, resulting in pain. Too soft may make the muscles around the spine remain spasmodic and fatigued for a long time, which in turn causes pain.
