When an upper neck bone (vertebra) becomes misaligned or moves out of its normal position and causes nervous system interference, this is referred to as a Subluxation. Subluxations can be caused by a wide range of stresses from the process of being born to 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 between your brain and body causing abnormal function to result.
As time goes by and a subluxation remains uncorrected, the spinal bones (vertebrae) and surrounding features such as discs can begin to degenerate. This degeneration becomes more difficult to reverse as time goes by as the surrounding muscles, nerves and bones begin to adjust to the new shape. The body is an amazing machine. It will start to accommodate these changes by compensating in other areas. The longer this goes on, the more difficult it is and the longer it takes to get back to near perfect position.
