The spine can feel or hear a ringing sound when moving, often for several reasons: first, a physiological ringing sound. There are joints and intervertebral joints between the vertebrae of the spine, and the vertebrae of the spine are connected together by intervertebral discs, and there are also many ligaments connected between the vertebrae. When moving, it causes friction between the ligaments and joints or joints and vertebrae, resulting in a ringing sound. This is a normal physiological phenomenon and generally has no effect on health. The second, seen in the degeneration of the spine. Degeneration can lead to deformation of the spine, poor alignment of the joints, and the formation of hyperplastic bridges between vertebrae as well as poor intervertebral disc flexibility. When moving, there is a frictional sound due to the degeneration of the bones and poor joint alignment. The third is spinal instability due to trauma or various causes. As a result of spinal instability, the unstable structures rub against each other when moving, resulting in a rattling sound and pain. In this case, if it is episodic and not accompanied by pain and other discomfort, it can be observed, with moderate rest and reduced activity. If there are other symptoms or the ringing is more frequent, it is better to go to the hospital for consultation.
