When a vertebra becomes restricted in a specific motion, this is referred to in the chiropractic profession as a subluxation. Subluxations can be caused by a wide range of issues raging from a minor slip or bump to a car accident or any sudden trauma. When a vertebra is subluxated, it begins to put pressure on nerves, blood vessels, and everything around it. This pressure comes with a price. The subluxation interrupts the natural pathways the messages sent from the brain need in order to be completed properly.
As time goes by and these remain untreated, the spine and surrounding features such as discs can being to degenerate. This degeration become more difficult to reverse as time goes by since the surrounding muscles, enrves, and bones adjust ot the new shape. The body is an amazing machine. It will start ot accommodate these changes by compensating in other areas. The longer this goes on, the more difficult it is to restore natural movement and function.
