Our conventional approach to medicine has taught us to look at the pain for the cause of a problem and commonly offers an only solution in the form of a pill or surgery.
The reality is much different. The human body is an incredibly complex piece of machinery, evolved over millions of years to function as one, as a unit. As soon as a piece of the puzzle changes, the rest immediately begins to compensate, to find a way, a solution, to adapt and to keep functioning for survival and the ability to do everyday activities.
Chiropractic takes this fact into account and looks to the body as a whole.
It is very much possible that a knee, an ankle problem is finely connected with issues higher, in the pelvis, lower spine or even the neck, and vice versa.
