Is it true that cracking your knuckles can easily lead to arthritis?

There is a certain amount of gas in the joints of the fingers. The gas and joint fluid mix to form certain bubbles. When the joints suddenly change position, the bubbles suddenly burst, forming a single, crisp sound.

This is a normal phenomenon and does not directly cause damage to bones or joints.

However, it is better to avoid such fun things as snapping your fingers to make sounds. If you accidentally damage the soft tissue of the joints, you will need treatment.
