What Is Sciatica?
Understanding your condition is the first step toward treating it effectively.
Sciatica is not a diagnosis in itself — it is a symptom describing pain, numbness, tingling, or weakness that follows the path of the sciatic nerve. The sciatic nerve is the largest nerve in the body, formed from five lumbar and sacral nerve roots and running from the lower back through the buttock, down the back of the thigh, through the calf, and all the way to the foot.
When a nerve root in the lumbar spine is compressed, irritated, or inflamed — most commonly by a herniated disc or lumbar stenosis — it generates pain along the nerve's entire distribution. This is why sciatica can cause symptoms anywhere from the lower back to the sole of the foot, even though the problem originates in the spine.
Crucially, the pain in your leg is not coming from your leg — it is a referred signal from the spine. This is why treating the leg alone does not work, and why physiotherapy, which addresses the source directly, is so effective. Most sciatica resolves without surgery when the underlying nerve compression is properly managed.
Quick Facts
What Causes Sciatica?
Several spinal conditions can irritate or compress the sciatic nerve roots. Identifying the specific cause is essential for effective treatment.
Lumbar Disc Herniation
The most common cause. The inner disc material ruptures through the outer wall and presses directly on a lumbar nerve root. L4–L5 and L5–S1 are the levels most often affected.
Lumbar Stenosis
Narrowing of the spinal canal or nerve root canals, often from age-related bone spur formation and ligament thickening, squeezes the exiting nerve roots and causes bilateral leg symptoms.
Piriformis Syndrome
The piriformis muscle in the buttock sits directly over the sciatic nerve. When tight or in spasm, it compresses the nerve, mimicking disc-related sciatica but with more buttock-dominant pain.
Spondylolisthesis
Forward slippage of one vertebra over another narrows the space for nerve roots to exit the spine, causing chronic nerve irritation with standing and walking.
Degenerative Disc Disease
Age-related disc thinning causes narrowing of the foramina (nerve exit canals), leading to chronic low-grade nerve root irritation with intermittent leg symptoms.
Sacroiliac Joint Dysfunction
Irritation of the SI joint can refer pain into the buttock and upper thigh in a pattern that resembles sciatica — important to differentiate as treatment differs significantly.
How Sciatica Feels
Sciatica has a distinct character. These are the patterns our therapists look for during assessment.
Burning or Electric Shooting Pain
A distinctive burning, electric, or shooting pain travelling from the lower back, through the buttock, and down the back of the leg — the hallmark of sciatic nerve irritation.
Numbness in Leg, Calf or Foot
Areas of reduced sensation in specific parts of the leg, calf, or foot indicate which nerve root is compressed — valuable diagnostic information for treatment targeting.
Weakness in Leg Movements
Difficulty lifting the foot (foot drop), weakness pushing off when walking, or leg giving way during activity — these indicate significant nerve compression requiring prompt assessment.
Worsened by Sitting
Disc-related sciatica typically becomes significantly worse with sitting, forward bending, and coughing — all actions that increase disc pressure and nerve tension.
Pins and Needles
Persistent or intermittent tingling in the thigh, lower leg, or foot suggests irritated nerve fibres — different from numbness but equally important to assess and treat.
One Side Only (Usually)
Classic sciatica affects one leg only — it follows a single nerve root. Bilateral (both legs) symptoms suggest central canal stenosis and require different management.
How Physiotherapy Treats Sciatica
We decompress the nerve, reduce inflammation, and rebuild the support system that protects it.
Our Results
At Premium Care, most sciatica patients experience a significant reduction in leg symptoms within the first 4–6 sessions.
- Leg pain dramatically reduced
- Numbness and tingling resolved
- Normal walking restored
- Sitting tolerance improved
- Recurrence prevented long-term
Nerve Root Localisation Assessment
Before any treatment, we need to identify exactly which nerve root is involved. We assess your dermatomal pain pattern (which part of the leg is affected), myotomal weakness (which muscle movements are weaker), and reflex testing. This neurological mapping tells us precisely where in the spine the compression is occurring — and that information determines every decision we make about your treatment.
Neural Decompression & Directional Preference
Most disc-related sciatica has a "directional preference" — one spinal direction (usually extension) that centralises and reduces symptoms, while the opposite direction worsens them. We identify and utilise this preference to reduce disc pressure on the nerve root quickly. This evidence-based McKenzie approach is one of the most powerful tools for acute sciatica relief.
Neural Mobilisation
Gentle nerve mobilisation techniques — called neural flossing or nerve gliding — restore the sciatic nerve's ability to move freely within its canal. When nerve tissue becomes sensitised and restricted, these techniques progressively desensitise the neural tract and reduce the hypersensitivity that causes ongoing symptoms even after the initial compression is resolved.
Manual Therapy & Electrotherapy
Lumbar joint mobilisation reduces mechanical compression at the affected level. Electrotherapy — including TENS and interferential current — provides significant pain relief during the acute phase and reduces the muscle guarding that often worsens nerve compression. We combine these alongside the active approaches for faster, more complete recovery.
Spinal Stabilisation to Prevent Recurrence
Once leg symptoms are resolved, we address the root mechanical problem — the disc or spinal structure that was the source. A structured core stabilisation programme, posture correction, and education about disc loading mechanics protects your spine from future episodes. Patients who complete this stage have dramatically lower rates of sciatica recurrence.
Treatment Techniques We Use
A combination of approaches targeting the nerve, the spine, and the surrounding muscles.
Manual Therapy
Lumbar joint mobilisation to reduce mechanical compression at the disc and facet joint level, combined with soft tissue release of the piriformis and surrounding gluteal muscles that may be contributing to sciatic nerve irritation.
View ServiceElectrotherapy
TENS and interferential current are particularly valuable for sciatica — they reduce the transmission of pain signals along the nerve and provide significant relief during the acute phase when movement-based treatment is limited by pain intensity.
View ServiceNeural Mobilisation & Exercise
Nerve gliding exercises to restore sciatic nerve mobility, directional-preference extension exercises to centralise disc pain, followed by progressive core and lumbar stabilisation work to protect the spine from future episodes.
View ExercisesExpected Recovery Timeline
Sciatica recovery is gradual but very achievable. This is the typical progression with proper physiotherapy.
Weeks 1–2
Leg pain begins to "centralise" — moves back toward the lower back. This is a positive sign.
Weeks 3–5
Leg symptoms significantly reduced. Numbness and tingling improving. Walking more comfortable.
Weeks 6–10
Nerve sensitivity resolved. Back strengthening and stabilisation work in progress.
Goal
Full recovery. Spine protected with long-term home programme.
Home Exercises to Start
These exercises are safe during sciatica when done gently. Stop any exercise that increases leg symptoms — that is the key rule.
Glute Bridge
Activates the gluteal muscles and reduces piriformis tension — one of the key contributors to sciatic nerve compression. Gentle version: keep the bridge low and avoid full hip extension in acute phase.

Bird-Dog
Trains the deep lumbar stabilisers — multifidus and transversus abdominis — to protect the disc and nerve root during limb movement. This is the most important long-term exercise for preventing sciatica recurrence, as it retrains the motor control pattern that protects the L4–L5 and L5–S1 levels.
Full Instructions
Plank
Builds isometric core endurance — the ability to hold the spine stable under load over time. This directly reduces disc pressure during daily activities and protects the nerve root from re-compression. Start at 15–20 seconds and build gradually as pain allows.
