Chronic pain is a disordered that affects the lives of millions of people each year. Pain is the number one complaint for which people consult physicians; two out of three patients seek relief for pain (Hart, 1974, Chaplin, E., 1991). It is also the most common and frequent cause of suffering and disability that impairs quality of life. Nearly one third of Americans suffer from chronic or reoccurring pain (Gershon, 1986). An estimated of fifty million people suffered from chronic pain, which cost the nation anywhere from $100 million to $50 billion a year in medical costs, lost income, lost productivity, and compensation costs (Cook 1998).
