Scientists have conducted few studies on whether cracking your knuckles can cause arthritis or otherwise harm your hands.
Some studies suggest that you can snap your knuckles all you wish, and it won't cause osteoarthritis.
However, other studies indicate that around-the-clock cracking may damage the soft tissue around the joints, make your hand swell, and weaken your grip.
