Answer Wiki. As long as popping/cracking your joints does not cause you pain, and you have otherwise normal healthy joints[1], you're probably ok. Gases: Your joints are lubricated with synovial fluids, which contain oxygen, nitrogen, and carbon dioxide.
âAnd in the case of the neck pop, you hear a crack as the gas pops out of the fluid.â. Generally, joint cracking is not harmful, Dr. Visco said, but when extreme stretching becomes a habit (to relieve tension, for instance), it can cause irritation of soft tissue or cartilage. And because important nerves and blood vessels run through the neck, amateur neck-cracking is ill advised. A gentle stretching routine is preferable.
