Under normal circumstances, there is synovial fluid between joints. This viscous liquid is like a lubricant to prevent joints from wearing each other, and its texture is similar to that of raw egg liquid.

Synovial fluid contains phagocytes, which can help remove bone and cartilage fragments from joints.

However, when our joints bend and straighten, the joint gap will become larger, but the amount of joint synovial fluid will remain the same, which will create a low pressure area, leading to the release of a small number of bubbles, similar to the emergence of carbon dioxide in soda.

When we bend a joint, it doesn't ring every time. This is because the bubbles released by the joints are scattered in the synovial cavity, and the surrounding liquid needs to exert certain pressure on them, so it will make a thumping sound.

Usually, the same joint will wait for 20 minutes or half an hour before it appears with the next flexion joint.

That is to say, not every time there is a snapping sound in flexion and extension joints, but in most cases it is a physiological snapping sound, which is not very harmful to the body. Don't bend your joints frequently, even if the physiological jerk does no harm to your body, such as breaking your fingers habitually and bending your joints violently to prevent ligament strain or other diseases.

It should be noted that if every flexion and extension joint will snap, it may be pathological snap, joint inflammation, trauma and other reasons, or joint synovial fluid is insufficient, which can not alleviate the impact between bones.

Pathological changes in the hands and elbows can also lead to joint ringing. Pay attention to medical observation this morning to avoid aggravating and delaying treatment.
