As time goes by and a subluxation remains untreated, the spine 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.
