What is the “popping” sound that I hear?

When a joint is subluxated, it is not moving properly. All joints require motion for proper nourishment and function. Movement for joints can almost be described as the “breath” of the joint. With every breath that we take air moves in and out of our lungs. In the joint, when motion is restricted that “breath” does not occur properly. The adjustment allows the joint to exhale letting out gas bubbles and making the “popping” sound called a joint cavitation.
