Does cracking your knuckles make them fat?

Yes it can make them fat. And it will not cause arthitis unless your doing it every 15 mins of the day 24/7... But if you don't you could get loss of strenght in your hand and soft tissue damage.. All that's happening when you crack them is a realy thick liquid between your joints make a buble and once you go to crack the buble pops and gas releases.
