The Short Answer

Escaping gases. Synovial fluid present in your joints contains oxygen, nitrogen, and carbon dioxide, when you pop, these bubbles escape. This can relieve pressure. Cracking also leads to momentary ligament looseness and relieves tension. Most importantly, though? Popping triggers the release of local endorphins, which cause a near instant but temporary relief like pain medication making you unaware that your back hurts.
