Low back pain: causes, prevention and treatment

Low back pain is something most people experience at least once, and it is usually not a sign of serious disease. Muscle strain, poor posture and inactivity are the most common causes. Most cases improve on their own within a few weeks.

Types of back pain

Back pain can be acute (lasting a few days to weeks) or chronic (over 3 months). Most often it comes from muscles and ligaments and appears without a specific 'injury'. Pain that radiates down the leg (sciatica) may involve a pinched nerve root and needs separate attention.

The most common causes

Back pain is usually not a disease but the result of daily habits:

• Long hours of sedentary work and poor posture
• Lifting with poor technique (bending the back)
• Inactivity and weak core muscles
• Excess weight, stress and poor sleep

Relief at home

Complete rest (bed rest) is not advised in the first days — gentle movement actually speeds recovery. In the first 48 hours a warm compress eases muscle tension; a good sleeping position (on your side with a pillow between the knees) relieves pain. A short course of pain relief can be used if needed.

Helpful exercises and prevention

Strengthening the core is the most effective way to prevent recurring back pain:

• Stand up and move for 1–2 minutes every hour
• Lift with your knees, don't bend your back
• Strengthen back, abdominal and hip muscles (bridge, plank, swimming)
• Sit upright and raise your screen to eye level
• Maintain a healthy weight

Treatment options

Most cases improve within 4–6 weeks with conservative measures (movement, physiotherapy, pain management). For persistent or radiating pain a doctor may recommend physiotherapy, medication or imaging. Surgery is rarely needed and only for specific problems such as nerve compression.

When to see a doctor

See a doctor promptly if pain radiates down the leg, with numbness, leg weakness, loss of bladder/bowel control, unexplained weight loss, fever or pain at night.

Frequently asked questions

Is rest or movement better for back pain?

Light movement after short rest is more helpful; long bed rest delays recovery.

Is an MRI always needed?

No. Without warning signs, most back pain is treated without imaging.

Is a back brace helpful?

It can support you for a short time, but long-term use weakens the muscles. Strengthening the muscles is what matters.
