This is an interesting article. I do not personally suffer from any type of chronic pain, however, I have two parents who both do suffer from differing forms. My father with his knee and back, and my mother with overall systemic weakness and fragility - pain is easily induced from things which I would hardly even feel. This will give me something to ponder. I find myself having a hard time believing that a simple introduction to this concept of pain would have a significant impact upon an individual who suffers from serious chronic pain. Alas though, I would love to be wrong!
