Lumbar muscle strain

Overview

A lumbar muscle strain is a common, self-limiting injury to the muscles and connective tissue of the lower back, usually after lifting, twisting or unaccustomed activity. It typically settles within a few weeks with movement and gradual return to load.

Symptoms

• Sudden onset of localised back pain
• Muscle tightness or spasm
• Pain with movement that eases with rest positions
• Tenderness over the affected muscles

Causes

• Lifting or twisting under load
• Sudden unguarded movement
• Fatigue and unaccustomed activity

Treatment

• Reassurance and early gentle movement
• Short-term pain relief and heat
• Graded return to normal activity
• Strengthening to reduce recurrence
