When pain continues, there are changes that occur to our pain messaging system. If you relate our bodies to a computer, the bones, muscles, organs and tissues are the hard drive. The hard drive is easy to visualize, with tests, x-rays, and examinations. The software is our pain messaging system and there are no tests or methods to see the software. When pain continues in our body, there are changes that happen to our pain messaging system and these changes make chronic pain a disease and no longer a symptom.
