Most back pain is what's known as "non-specific" — it isn't caused by anything serious, and is often linked to poor posture, muscle strain, prolonged sitting, or lifting awkwardly. It usually improves on its own within a few weeks.
Staying as active as you comfortably can, rather than resting for long periods, tends to help recovery more than bed rest. Gentle movement, over-the-counter pain relief and applying heat can all ease symptoms. See your GP if pain is severe, doesn't improve after a few weeks, spreads down a leg, or is accompanied by numbness, weakness, or loss of bladder or bowel control, as these can be signs of something needing urgent attention.
