Question: what makes the popping sound and what exactly is moving around in your fingers? Also what harm can it cause later on?
Answers: what makes the popping sound and what exactly is moving around in your fingers? Also what harm can it cause later on?
To produce the clicking sounds, many people bend their fingers into unusual positions. These positions are usually ones that their own muscles are unable to achieve, and which are not commonly experienced in everyday use. For example, bending a finger backwards away from the palm (into extension), pulling them away from the hand (distraction), compressing a finger knuckle toward the palm (into flexion), or twisting a finger about the first bone's axis (torsion).
Cracking within the body may also be caused by a breaking bone.
The snapping of tendons or scar tissue over a prominence (as in snapping hip syndrome) can also generate a loud snapping or popping sound.[2]
[edit] Source of sound
The physical mechanism is as yet unproven, but suggested theories include:
1. Cavitation within the joint
