What it is
Back pain is one of the most common health complaints, and nearly everyone experiences it at some point. It ranges from a dull ache to sudden sharp pain and is usually short-lived, settling within days to weeks.
Most back pain is mechanical, coming from muscles, ligaments, discs, or joints, rather than from a serious disease. Pain that lasts beyond three months is called chronic and needs a more structured approach.
Common causes
Frequent triggers include muscle or ligament strain from lifting awkwardly, sudden movements, or poor posture over long periods. Age-related changes in the discs and joints, a slipped or bulging disc, and narrowing of the spinal canal can also cause pain, sometimes with pain or tingling running down a leg.
Being overweight, inactive, or smoking raises the risk, as do jobs involving heavy lifting or long sitting.
Self-care and treatment
For most acute back pain, staying as active as the pain allows works better than bed rest. Gentle movement, heat or cold packs, and over-the-counter pain relief used as advised usually help, and most episodes settle within a few weeks.
Ongoing pain benefits from exercise that strengthens the back and abdomen, weight management, good lifting technique, and attention to posture and workstation setup. Physiotherapy helps many people, and surgery is reserved for specific structural problems.
When to seek help
Medical advice is needed for pain that is severe, follows an injury, lasts more than a few weeks, or comes with leg weakness, numbness, fever, or unexplained weight loss.
Loss of bladder or bowel control, or numbness in the saddle area, with back pain is an emergency, because it can signal compression of the spinal nerves that needs immediate treatment.
