Back pain is one of the most common health complaints worldwide, affecting individuals of all ages and races. While occasional back pain can be caused due to temporary strain or injury, chronic back pain can last for weeks, months, or even for years affecting one's life and work. Backpain might vary in intensity from a steady, dull ache to an abrupt, acute pain that might go down the leg. It can sometimes develop gradually due to age-related degenerative changes in the spine, or it can occur quickly as a result of an accident, a fall, or carrying something heavy.
