The area that hurts is usually the victim, rather than the culprit. It's compensating for something else that's not moving well, because the body has lost its natural alignment. An example is back pain caused by hips no longer working well from years of sedentary living. The back has to chime in and help dysfunctional hips, resulting in the back overworking and hurting.
Restoring natural movement and alignment to the whole body allows pain to naturally disappear. It's a bit like restoring 'factory settings' to the body. All the clunky, painful, imbalanced movements disappear. Instead, your body moves efficiently, effortlessly and pain-free, as it's naturally designed to do.
Restore natural movement to your whole body and you'll address the fundamental reason for the pain, no matter if you have back, hip, knee, shoulder, foot, sciatic pain or many other kinds of pain.
