Snapping and popping of joints is common. The sound you hear is caused by air bubbles in the synovial fluid – the liquid that surrounds and lubricates your joints – and by the snapping of tightly stretched ligaments as they slide off one bony surface onto another.I personally feel that as a 26 year old male you must be feeling comfortable after clicking sounds which is bcoz of Endorphins.they are chemicals produced by the pituitary gland that are meant to manage pain in your body, and they can make you feel super satisfied when you crack a joint.
