PAIN; A HEALTH BURDEN, A RESEARCH AMBIGUITY!!!

To alleviate the burden of uncontrolled pain is an essential public, health and economic challenge. Chronic pain is often difficult to diagnose and manage, hitting millions of people and families as a chronic illness that not only raise healthcare expenses but also produce a huge burden of pain-related disability. Though acute pain is a critical process but it can be resolved. With unrelenting pain and injury it becomes a chronic condition and illness that develops into long-term human suffering and to prevent lost productivity within our society. Instead of receiving effective relief, patients with persistent pain often find themselves in an endless cycle, seeing multiple health care providers, including specialists in different areas other than pain, who are not prepared to respond effectively. More needs to be known about the impacts of chronic pain regarding physiological, pathophysiological, psychological and social consequences. Globally there is a lack of enough data needed to have clear concepts of unknown and partially know mechanisms and methods to manage these enormous pain-related costs represent both a great challenge and an opportunity in terms of improving the quality and cost-effectiveness of care.
