True or False?
back, neck = true
knuckles = false
basically, if you have a disc in the area, cracking your own could cause more problems in the future.
knuckles have no disc... it's just synovial fluid joint capsules. cracking your knuckles will actually improve dexterity and motion. you've got a better chance of getting osteoarthritis in your hands if you never crack your knuckles, but not by much.
cracking them too much, however, could potentially cause a problem by causing too much joint laxity. too much = more than what a reasonable person would consider a normal amount of knuckle cracking, basically.
