Lower back pain is an extremely common disorder affecting the bones and muscles of the back. Acute lower back pain often corrects itself within a few weeks, yet for some it is disabling and can become chronic in nature.
The back is made up of interlocked structures such as bones, joints, muscles, ligaments and tendons. It is supported by the spine, which consists of 24 moveable bones known as the vertebrae, in addition to the sacrum and coccyx. Soft cushions called discs are found between the vertebrae that absorb pressure and allow the spine to move and keep the body upright. The lower back not only provides structural support and facilitates movement, it also protects tissues and organs.
Lower back pain often manifests as tension, stiffness or pain felt in the area. Pain of this type is usually felt during standing and moving the lower body.
