Summary
Lower back pain is the leading cause of disability worldwide, affecting up to 80% of adults at some point. Most cases are caused by muscle strain or disc problems and resolve within weeks with appropriate treatment. Chronic back pain requires physiotherapy and lifestyle changes.
Key Takeaways
90% of lower back pain resolves within 6 weeks with conservative management.
Prolonged sitting is a major risk factor for disc degeneration.
Core strengthening is the most effective long-term treatment.
Bed rest is no longer recommended — staying active speeds recovery.
Benefits
Physiotherapy reduces lower back pain without medication in most cases.
Core strengthening reduces the risk of recurrent back pain by up to 40%.
Understanding posture and ergonomics prevents future episodes.
Most Common Causes
Muscle Strain: The most common cause, often from lifting incorrectly or sudden movements.
Herniated Disc: Inner disc material pushes through the outer layer, pressing on nearby nerves.
Sciatica: Pain that travels from the lower back down one or both legs due to nerve compression.
Osteoarthritis: Wear and tear of the spinal joints, most common in people over 50.

Short-term rest (1–2 days) may help during the most acute phase, but prolonged bed rest delays recovery. Gentle movement and walking are recommended as soon as pain allows.
Yes — gentle, low-impact exercise is one of the best treatments for lower back pain. Walking, swimming, and cycling are excellent choices. Avoid heavy lifting until assessed by a physiotherapist.
