The Truth About Clicking Joints: Should You Stop Cracking Your Knuckles?
Originally Published 2 years ago — by The Guardian
Knuckle-cracking does not appear to cause arthritis, according to a doctor who cracked the knuckles of his left hand for 50 years without developing the condition. The satisfying pop of a knuckle crack is believed to come from small bubbles in the synovial fluid surrounding the joint. While occasional joint cracking is normal, persistent pain, swelling, or deformity may indicate an injury or arthritis and should be checked by a health professional. Overdoing knuckle-cracking can lead to acute injuries, as described in a report by a hand surgeon.
