Back pain can have many possible causes. Muscle strain and posture-related problems are common, while arthritis, disc problems and other conditions can also contribute.
The location of pain alone cannot reliably identify its cause. Most uncomplicated episodes improve, but persistent or severe pain should be assessed professionally.
Seek urgent medical attention if back pain occurs with significant leg weakness, loss of bladder or bowel control, numbness around the groin, or after a serious injury.
