At first learning about the human body can be confusing at best, for the human body is a complex thing to attempt to understand.
In 2007 prominent physiotherapists published a paper on regional interdependence. This is a type of pain that occurs at a distant site to the root cause of pain (nociceptive). E.G that the thoracic spine can be the cause of neck pain, and a not so obvious one that the foot can stop head rotation short. Essentially almost any part of the body can affect any other part as we are well interconnected (hopefully!). The body in fact is bidirectional within itself (Tech bit: in a lower motor neurone way). The knee could cause the painful low back experience of an individual but does not give any pain at the knee. Regional Interdependent pain is different to referred pain as referred pain had been mapped and is known. In a case of interdependent pain the body worker assessing you would have to understand the link in order to help you with your problem. If the site of pain is treated then the problem can be made worse in the case of interdependent pain. Body workers such as chiropractors have ways of identifying areas to treat that are not pain based. Which is why some people have regular care; gaining benefit without the pain involved in a flare up.
Chiropractors are educated intellectually and trained in manual procedures differently to specialist manual physiotherapists, hence why in the case of a person with regional interdependent pain, we find that tacitly the concept is already part of chiropractic care plans to help musculoskeletal pain experiences. In other words: My pain does not always signify the body part that requires treatment. There will be an order of care in your chiropractic care plan that involves you finishing the course of treatment. Chiropractic is more than a quick click.
