Please note: Before trying to crack a stiff or sore neck, consider seeking help from a qualified health professional (listed below). If you find neck cracking becomes a habit or doesn't provide lasting relief then it's probably time to seek professional help.

The cracking sound that you hear when you move your back or neck in a certain way may be an air bubble forming and rapidly collapsing on itself. In most cases, this is not harmful. It may even feel good and relieve some tension in your stiff neck. Cracking your neck can provide temporary relief, although it’s usually best to allow a qualified chiropractor, osteopath or other trained professional treat your stiff or sore neck. Be aware that cracking your neck the wrong way can have serious unintended consequences and may lead to unpleasant side effects and possibly long-term harm. It may also not deal with the root cause of your problem. [1]
