Lumbar Disc Herniation: Physiotherapy or Surgery?

A lumbar disc herniation occurs when material from the disc pushes beyond its outer ring and irritates a nerve root. The diagnosis sounds alarming, yet its natural course is far more favourable than most people expect.

Typical presentation

• Pain radiating from the back into the buttock, leg and sometimes the foot
• Worse with coughing, sneezing and straining
• Numbness or tingling in the leg
• Often aggravated by sitting and bending forward
• Occasionally weakness in the foot or big toe

Back pain that does not radiate into the leg usually has a different source.

The natural course

In a large proportion of cases symptoms improve substantially within 6–12 weeks. The body resorbs the extruded material over time — a process that has been demonstrated on repeat imaging. The first approach is therefore supportive management rather than immediate surgery.

What physiotherapy does

1. Pain management and positioning — finding the positions that relieve symptoms; these differ from person to person.
2. Staying active — short, frequent walks rather than bed rest.
3. Directional exercise — movements chosen so that leg pain moves back towards the spine (centralisation), which is a favourable sign.
4. Graded strengthening — trunk and hip endurance, light at first and progressively loaded.
5. Education — what the pain means, which movements are genuinely risky, and what recovery looks like.

Common misconceptions

• "I can never lift anything again." Lifting capacity is rebuilt with technique and graded loading. Permanent avoidance makes the back more vulnerable.
• "I must never bend my back." Bending is a normal movement. It may be limited in the acute phase, but not forever.
• "Sit-ups will fix it." Isolated abdominal work is not effective for back pain; trunk endurance and hip strength are both needed.

When surgery is considered

The following require urgent assessment:

• Loss of bladder or bowel control
• Numbness around the groin and saddle area
• Progressive weakness in both legs

This picture (cauda equina syndrome) is a surgical emergency.

Planned surgery is discussed when there is progressive muscle weakness, intolerable leg pain despite 6–12 weeks of appropriate care, or severe functional limitation.

Long term

Once symptoms settle, protecting the back means neither a permanent brace nor permanent avoidance:

1. Strength training twice a week (hips, trunk, back)
2. Regular walking
3. Breaking up long periods of sitting
4. Attention to sleep and stress, which directly affect the pain threshold
5. Rebuilding lifting capacity gradually
