Low back pain is a very common occurrence and is said to affect 80% of people at some time in their life.  Common causes of acute low back pain are sudden unexpected movements i.e. bending: lifting while twisting, or trauma such as a fall or a motor vehicle accident.

Others can injure their lower back simply if bending to brush their teeth.  The low back pain can come on instantly, with acute muscle spasm or locking.  Sometimes it is impossible to move or to straighten to an upright position.  Other acute low back pain can come on more slowly; up to 2 days post injury, as swelling gradually accumulates.
