Understanding Your Pain

What Is Sciatica?

This page is for you if you live in Kings Park, Blacktown, or the surrounding suburbs and are experiencing shooting pain down one leg, numbness in your foot or calf, or a deep ache in your buttock — and you want to understand what’s causing it before deciding on treatment.

Sciatica is not a diagnosis in itself — it is a symptom. It describes pain, numbness, or weakness that travels along the path of the sciatic nerve, which runs from the lower back through the buttock and down each leg to the foot. When something compresses or irritates this nerve, the result can be one of the most debilitating types of pain a person experiences.

In Australia, sciatica most commonly originates from a disc bulge or herniation at the L4–L5 or L5–S1 levels of the lumbar spine, where the nerve roots that form the sciatic nerve exit the spinal column. Other causes include piriformis syndrome, spinal stenosis, and degenerative disc disease.

At Kings Park Chiropractic, Dr. Brian Sin (M.Chiro, Grad Dip Chiro, DACCP) performs a thorough lumbar and neurological assessment to identify the exact source of compression before any treatment begins — because the cause determines the approach.

Symptoms

Do You Recognise These Signs?

Sciatic pain is highly individual — it can be a dull ache, a sharp electric shock, or a burning sensation. Here are the most common symptoms we see at Kings Park Chiropractic.

Shooting leg pain A sharp, electric, or burning pain that travels from the lower back or buttock down one leg — sometimes reaching the foot
Buttock ache Deep, persistent aching in one buttock that can be hard to position away from when sitting or lying
Foot & calf numbness Pins and needles, tingling, or numbness in the calf, heel, sole, or toes on one side
Worse when sitting Pain that intensifies with prolonged sitting, driving, or desk work and eases when moving or lying flat
Worse with sneezing Sharp pain shooting down the leg when sneezing, coughing, or straining — a hallmark sign of nerve root compression
One-sided pain Sciatica almost always affects only one leg at a time — bilateral leg pain may indicate a different condition requiring urgent assessment
⚠️ Seek urgent care if you develop weakness in both legs, loss of bladder or bowel control, or numbness in the groin or inner thighs — these may indicate cauda equina syndrome, a medical emergency.
Causes

What’s Causing Your Sciatica?

Sciatica is a symptom of an underlying problem, not a diagnosis in itself. Identifying the exact cause is critical — the treatment for a disc bulge differs significantly from that for piriformis syndrome or spinal stenosis. Here are the most common causes we assess and treat.

1
Disc Bulge or Herniation The most common cause. A bulging or herniated disc at L4–L5 or L5–S1 presses directly on the sciatic nerve root, producing the characteristic shooting leg pain.
2
Piriformis Syndrome The piriformis muscle in the buttock can spasm and compress the sciatic nerve as it passes through or beneath it — causing sciatica without any spinal involvement.
3
Spinal Stenosis Narrowing of the spinal canal or foramina (the openings where nerve roots exit) reduces the space available for the nerve, causing compression and sciatic symptoms — a form of pinched nerve at the spinal level.
4
Spondylolisthesis A vertebra that has slipped forward onto the one below can narrow the foramen and place direct pressure on the exiting nerve root.
5
Degenerative Disc Disease Age-related disc thinning reduces the disc height, narrowing the foramina and placing chronic, low-grade pressure on the sciatic nerve roots.
6
Facet Joint Hypertrophy Enlarged or arthritic facet joints can encroach on the nerve root canal, particularly in older patients where bone spurs form as part of the degenerative process.
7
Pregnancy Postural changes, increased lumbar load, and the relaxin hormone loosening pelvic ligaments can all compress or irritate the sciatic nerve during pregnancy.
8
Prolonged Sitting & Poor Posture Hours of sitting in poor postures increases disc pressure at L4–S1 and can trigger or aggravate sciatic symptoms — particularly common in desk workers and drivers.
Our Approach

How Chiropractic Helps Sciatica

Chiropractic care for sciatica aims to reduce the mechanical compression on the sciatic nerve, calm the surrounding inflammation, and restore normal lumbar and pelvic movement — so the nerve can heal and the pain resolves.

1
Lumbar Spinal Adjustment Precise, targeted adjustments to the lumbar spine restore normal joint movement, reduce disc pressure on the nerve root, and improve the space available for the sciatic nerve to exit the spine.
2
Cox Flexion-Distraction A gentle, non-thrust technique that applies controlled traction to the lumbar spine, decompressing the disc and creating negative pressure to help draw the bulge away from the nerve root. Well-suited for disc-related sciatica.
3
Dry Needling — Piriformis & QL Targeting trigger points in the piriformis, quadratus lumborum, and gluteal muscles that contribute to sciatic nerve compression and the referred pain pattern down the leg.
4
Rehabilitation Exercises Specific stretches and strengthening exercises targeting the piriformis, hip flexors, and deep lumbar stabilisers to reduce nerve tension, support the disc, and prevent recurrence.
A 2018 systematic review in the Journal of Manipulative and Physiological Therapeutics found that spinal manipulative therapy produced significant improvements in pain and disability in patients with lumbar radiculopathy. A separate clinical trial (Spine, 2006) found that Cox flexion-distraction produced clinically meaningful reductions in leg pain intensity in disc-related sciatica cases. The Australian Institute of Health and Welfare identifies back pain and sciatica as among the leading causes of disability and lost productivity in Australia, affecting an estimated 4 million Australians at any given time.

Safety & Evidence

Is Chiropractic Safe for Sciatica?

Chiropractic care for sciatica is safe and appropriate for most patients when performed following a thorough assessment. The key is correctly identifying the cause — treatment for a disc bulge differs from treatment for piriformis syndrome or spinal stenosis.

At Kings Park Chiropractic, Dr. Brian Sin (M.Chiro, Grad Dip Chiro, DACCP) performs a full neurological and orthopaedic assessment before treating any sciatica case. This includes testing reflexes, muscle strength, and sensation to establish whether nerve involvement is present and to what degree. Contraindications — including cauda equina syndrome, severe disc herniation with progressive weakness, and vascular conditions — are screened for at every first visit.

Where chiropractic adjustment is not appropriate, alternatives including Cox flexion-distraction, dry needling, and rehabilitation exercises are available — and Dr. Brian will refer when imaging or specialist input is required.

Is it safe to get adjusted with a disc bulge causing sciatica? In most cases, yes. Chiropractic adjustment and Cox flexion-distraction are well-established approaches for disc-related sciatica. The technique and force are always adapted to your presentation. Severe or progressive neurological deficit — such as worsening foot drop or loss of bladder control — requires urgent imaging and is not suitable for routine chiropractic management.
Who should not receive lumbar manipulation for sciatica? Patients with suspected cauda equina syndrome, severe osteoporosis, spinal fractures, active malignancy, or rapidly progressive neurological weakness require a modified approach or immediate medical referral. This is why the assessment always comes first.
What if I don’t want a spinal adjustment? That’s completely fine. Cox flexion-distraction, dry needling, soft tissue therapy, and rehabilitation exercises are all effective options for sciatica that do not involve manipulation. Just let us know your preference at your first visit.

Common Questions

Frequently Asked Questions

Can a chiropractor fix sciatica?+
Yes — chiropractic is one of the most effective conservative treatments for sciatica, particularly when caused by a lumbar disc bulge, facet joint irritation, or piriformis syndrome. The goal is to reduce the mechanical compression on the sciatic nerve so the nerve can heal and the pain resolves. Results depend on the cause, severity, and how long the condition has been present. Most patients experience meaningful improvement within 4–8 weeks of consistent treatment.
How long does sciatica take to heal with chiropractic?+
Acute sciatica from a muscle or joint irritation often responds within 4–6 visits over 2–3 weeks. Disc-related sciatica typically requires a longer care plan of 8–12 visits over 4–8 weeks, with the leg pain usually resolving before the lower back pain fully settles. Chronic sciatica that has been present for months may take longer. Dr. Brian will give you a realistic timeframe after the first assessment.
What is the difference between sciatica and piriformis syndrome?+
Both conditions produce sciatic-like pain down the leg, but the location of compression is different. True sciatica originates from compression of a nerve root in the lumbar spine — usually from a disc bulge at L4–L5 or L5–S1. Piriformis syndrome occurs when the piriformis muscle in the buttock compresses the sciatic nerve as it passes beneath (or through) the muscle. The distinction matters because the treatment is different — lumbar disc problems are treated differently from piriformis muscle tightness. Assessment — including specific orthopaedic tests for both conditions — is the only reliable way to tell them apart.
Should I see a chiropractor or physio for sciatica?+
Both professions can treat sciatica effectively. Chiropractors focus on diagnosing and treating the spinal or pelvic cause of the nerve compression — spinal adjustment and Cox flexion-distraction are core tools. Physiotherapists tend to emphasise exercise rehabilitation as the primary approach. For sciatica with a clear joint or disc cause — or related lower back pain — chiropractic often produces faster initial pain relief. For long-term rehabilitation and return to sport or work, both approaches have value. Many patients benefit from both, and Dr. Brian will refer to a physiotherapist when exercise-based rehab is the priority.
Is it safe to get adjusted when I have a disc bulge causing sciatica?+
Yes, in most cases. Lumbar adjustment and Cox flexion-distraction are well-supported treatments for disc-related sciatica. The technique is always adapted to your specific presentation and level of pain — there is no one-size-fits-all approach. If you have worsening neurological signs such as progressive leg weakness or loss of bladder or bowel control, these require urgent medical assessment before any chiropractic treatment.
Can sciatica go away on its own?+
Some mild cases do resolve without treatment — particularly those caused by a temporary muscle spasm or minor postural strain. However, Australian data shows that 60% of sciatica sufferers still have symptoms at 12 months without treatment. Disc-related sciatica that is left untreated can lead to chronic nerve sensitisation, muscle wasting in the leg, and persistent disability. Early treatment consistently produces better and faster results than waiting. If your sciatica has been present for more than 2–3 weeks, a proper assessment is worthwhile.
