When a vertebrae becomes misaligned or moves out of its normal position, this is referred to as a Subluxation. Subluxations can result from a variety of causes ranging from a minor slip or bump to a car accident or any sudden trauma. When a vertebrae is subluxated, it can put pressure on nerves, blood vessels and other soft tissues. This pressure comes with a price. Pressure on these structures alters their function.
As time marches on and a subluxation is left untreated, the spinal bones and adjacent tissues such as discs can begin to degenerate. This degeneration becomes worse as time goes by, and the surrounding muscles, nerves and bones must adjust to the changes created by the degeneration. The body is an amazing machine. It will accommodate these changes by compensating in other areas. The longer this continues, the more difficult it becomes to correct.
