Snap, Crackle, Pop

Do you crack your knuckles? Have you been told that this habit will cause problems in your hands like arthritis? Although conventional wisdom says that it must cause problems, research says otherwise. In fact, there have been many studies; all say the same thing, knuckle cracking does not cause arthritis. However, knuckle cracking over a long period may cause a loosening of ligaments in the hands. -Dr. Joshua Levitt
