Whether I’m walking on tippy toes or running, my toe and ankle joints will make sounds as if they have in-built anklets. My brother’s joints produce similar music and I kid you not, but he has a rhythm of his own. Pulling the finger and hearing a pop sound didn’t count – you had to forcefully flex (bend) the joint and hear a loud sound to be crowned champion. When you hear a pop or snap in your joint and experience pain and swelling, then you require medical attention. The cracking sound is actually coming from the compression of nitrogen bubbles that naturally occur in the spaces of the joints.
