In the U.S., up to 80% of the population experiences some form of low back pain at some time in their lives. It's the second most common reason people see their doctor. But as debilitating as back pain can be, most instances of it are manageable, and people who get adequate rest and proper exercise often see improvement within a matter of weeks.

Injuries such as sprains or fractures or more severe injuries such as a fall or an auto accident.
