Lower back pain (LBP) or lumbago is a condition involving the muscles and bones of the back. A sore lower back can occur suddenly, in many cases the cause relates to ‘untrained’ muscles or unfamiliar movements.
Pain in the lower back can be caused by a variety of problems within the complex, interconnected network of spinal muscles, nerves, bones, discs or tendons in the lumbar spine.
Pain, tension or stiffness in the lower back is something that most of us experience at some stage, and in many cases it settles down after a few days.
Typical sources of lower back pain may include:
- Irritation of the large nerve roots that connect the lower back with the legs
- Inflammation of the smaller nerves that supply the lower back
- Straining of the large paired lower back muscles (erector spinae)
- Damaged bones, ligaments or joints
