It's one of my biggest pet peeves! & no it is not okay, if you crack your knuckles, when your cracking them, your hand can stay like that forever & you can get injured really badly which is why I don't crack my neck, back, or knuckles unless it does it by its self! ~Kate

Only crack them if they are stiff but dont always do it because on your neck you can snap your spinal chord but other wise you just get arthritis (i think). also it should crack by itself if it truly is stiff and that is completely harmless.(that im sure about).
