Is it bad to crack your knuckles?
I wish my father had known the answer to this question, because maybe he would have yelled at my brother less. Cracking your knuckles is not as bad as people think. The usual concern is that knuckle popping causes arthritis. This does not happen. Chronic knuckle cracking may cause other types of damage, including stretching of the surrounding ligaments and a decrease in grip strength, but not arthritis. The popping sound is produced in the joint when bubbles burst in the synovial fluid surrounding the joint.
