Answer #1

Cavitation within the joint—small cavities of partial vacuum form in the fluid and then rapidly collapse, producing a sharp sound. This explains the popping that can occur in any joint, such as during spinal manipulation. Synovial fluid cavitation is the most likely theory and substantial evidence exists in support of it. Cracking your knuckles releases gases from the joints.[2] Rapid stretching of ligaments.[1] Intra-articular (within-joint) adhesions being broken…

basically saying, it is a normal reaction with your body. it has yet to be proven that these SNAPs are of any real medical relevance.

Answer #2

when I said strecthing… anytime you move a muscle, you either stretch it, or contract it. thats how the human body works! som if you move your leg,. you are strateching your ligiments! not growing persay!

Answer #3

The cracking sound in your joints is caused by the release of gasses in your bloodstream. It’s nothing to worry about generally. Some people have suggested there is a link to purposefully doing that & arthritis, or other ailments as you age, however, there aren’t any medical studies that are published in reputable journals that support this.

IF it bothers you, try to stretch more and do regular, light aerobic exercise as it should minimize this kind of cracking sounds. For more, better advice, consult your doctor or physician.
