Why are there noises in moving joints?
When moving joints, such as breaking finger joints, you sometimes hear a bang, because there is some lubricating fluid in the joint cavity, which contains gas.
When moving the joint, these gases will be squeezed out of the liquid, thus making a sound. Frequent snapping of finger joints will not lead to arthritis, but it will reduce the grip strength. This habit should be changed.
