Chiropractic treatment usually consists of safe and gentle spinal manipulations to free joints in the spine and related areas, which have become impeded in some way. This often requires short, sharp, pressure applied to joints that results in an audible ‘pop’. It often results in instant relief of symptoms, and some patients report a rise in feelings of wellbeing. The ‘pop’ these procedures cause is nothing to worry about they are just bubbles of air ‘popping’ in the joint fluid as the pressure is released – much like any other hydraulic system.
