What is the “Popping” Or “Cracking” Sound?
The popping sound is gas! Between each spinal joint are lubricating fluids. With some adjustments, gases escape due to pressure being placed on your spine. This pressure causes gases to escape and creates a popping sound. It is similar to when champagne or a can of pop is opened. The noise is from a change of pressure. Not all adjustments will create a sound so if you didn’t hear anything, the adjustment did not “fail”. The goal of an adjustment is to put a force through an area that is stuck, not to produce a sound.
