1.Introduction

Whatispain?

The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage."

PAIN

“Chronic pain has been increasing in prevalence. It is considered the most underestimated health care problem impacting quality of life. A number of epidemiological studies conducted in different parts of the world, reported prevalence rates of chronic pain ranging from 12-80%. Chronic pain has detrimental effects on physical and mental health, daily activities, family relationships, employment and economic well-being of the sufferers and family caregivers. Since the epidemiological studies about chronic pain in Lebanon are limited, the aim of this article is to help understand the magnitude of the problem and to depict strategies for the prevention and management of chronic pain.” [1]
