What happens if you crack your joints?

Bits of cartilage are torn away every time you crack a joint. When you feel like you need to crack a part of your body you often dont crack the right place. The only reason you feel good is because there is a chemical release in the body that tells your brain "that feels good."
the effects of cracking joints are injury of the ligaments surrounding the joint or dislocation of the tendons ( attachments of muscles to bones) which improved with conservative treatment. also studies have been shown that people who crack their knuckles have reduced grip strength than people who dont.
