Sciatica Treatment Without Surgery: How Physiotherapy Works

What Sciatica Actually Is

Sciatica is a symptom, not a diagnosis. It describes pain travelling along the sciatic nerve: from the lower back, through the buttock, down the back of the leg, and sometimes into the foot. The pain is often described as burning, shooting, or electric — and it can be completely disabling.

The most common cause is a lumbar disc bulge pressing on one of the nerve roots that form the sciatic nerve. Other causes include piriformis syndrome (where the piriformis muscle compresses the nerve) and lumbar stenosis. In over 90% of cases, sciatica resolves without surgery. Physiotherapy is the most evidence-supported treatment.

How I Diagnose Sciatica Online

I guide patients through the Straight Leg Raise test, slump test, and dermatomal assessment via video — these are highly sensitive for identifying nerve root irritation and determining which nerve level is affected. Combined with a review of any MRI imaging you have, this gives a clear clinical picture that directs treatment precisely.

The Physiotherapy Treatments That Work

Neural Mobilisation (Nerve Flossing)

Specific movements that gently mobilise the sciatic nerve through its full path, reducing adhesions and desensitising the irritated nerve. This is the most important technique for acute sciatica and can be taught and performed at home following an online demonstration.

McKenzie Extension Exercises

For disc-related sciatica, extension movements often centralise the pain — moving it from the leg back toward the spine — which indicates recovery. These must be prescribed based on your specific presentation; the wrong direction can worsen symptoms.

Core Stabilisation

The deep spinal stabilisers — transversus abdominis and multifidus — protect the disc from further irritation. Specific core exercises that do not aggravate the nerve are essential for long-term recovery and preventing recurrence.

What to Avoid with Active Sciatica

• Prolonged sitting (stand every 30 minutes)
• Bending forward while twisting simultaneously
• Carrying heavy loads with a bent spine
• High-impact activities during the acute phase
• Slumped posture that increases disc pressure

Red Flag: When Sciatica Is an Emergency

Seek emergency medical attention immediately if sciatica is accompanied by loss of bladder or bowel control, or numbness in the groin or inner thighs. These may indicate cauda equina syndrome — a surgical emergency requiring immediate attention.
