Sciatica Pain? Here’s What’s Really Going On – And How to Fix It (Not Just Settle It)
Sharp leg pain. Burning. Pins and needles. Or a deep ache running from your back into your calf or foot.
If that sounds familiar, you’re likely dealing with sciatica.
Sciatica is common and is also commonly misunderstood.
The good news? Most cases respond very well to the right treatment.
This guide explains sciatica in plain English.
No fluff. No fear tactics. Just what works.
TL;DR: Sciatica | The key takeaways
Sciatica is nerve pain, not a disease
- Sciatica is an umbrella term and doesn’t indicate the cause
It usually comes from the lower back or hip
Rest alone doesn’t fix it
Targeted exercise and education work best
Early physio care leads to faster recovery
What is Sciatica?
Sciatica isn’t a diagnosis on its own. It’s a symptom and umbrella term used to describes pain caused by irritation of the sciatic nerve, the largest nerve in the body.
This nerve starts in the lower spine (lumbar region), passes through the pelvis and buttock, then travels down the back of the leg.
When the sciatic nerve is irritated, compressed or sensitised, pain, tingling or numbness tends to follow.
Think of it like a kinked garden hose. The problem isn’t the water, it’s the pressure on the hose upstream.
Common Sciatica Symptoms
Sciatica usually affects one side (unilateral).
You may notice:
Sharp, shooting pain down the leg
Burning or electric-type pain
Pins and needles or numbness
Weakness in the leg or foot
Pain worse with sitting, bending, straining or coughing
Back pain itself may be mild or even absent.
What Causes Sciatica?
There isn’t one cause for sciatica.
These are the most common ones we see in clinic.
Disc bulge or disc herniation
A spinal disc presses on a nerve root.
Common triggers:
Prolonged sitting
Heavy lifting with poor technique and inadequate trunk strength
Sudden twisting movements
Lumbar spine stiffness or joint compression
Reduced movement in the lower spine can irritate nerve roots without a disc injury.
Piriformis syndrome
The piriformis muscle becomes thick/tight in the buttock and compresses the sciatic nerve and often linked to:
Long periods of sitting
Running or cycling
Poor hip control
Poor load management
Rapid increases in:
Training volume
Manual work
Standing or sitting time
Nerve sensitivity
Sometimes the nerve is irritated or tight even without major structural damage.
This is good news.
Sensitive nerves respond well to the right rehab and mobilisation exercises.
What makes sciatica worse?
These are common flare-up triggers:
Sitting too long
Slouching
Repeated bending
Avoiding all movement
Stretching aggressively through pain
Rest alone rarely fixes sciatica because you are not addressing the underlying cause and biomechanical imbalances.
Should you get an x-ray or mri for sciatica?
More often than not, the answer is no.
Many disc bulges show up on scans without causing pain and is a common “false positive” finding.
Scans are usually only needed if there are red flags like:
Progressive leg weakness
Loss of bladder or bowel control
Severe trauma
A thorough physiotherapy assessment often provides more useful answers than imaging alone.
A scan is only a very small piece of the puzzle.
Best Evidence-based treatment for sciatica
Accurate diagnosis
Not all leg pain is sciatica and requires a thorough physio assessment to identify the true cause and contributing factors.
Education & load control
You are responsible for your own recovery. The physio is here to guide your journey to recovery but you make changes to achieve results.
It is improve to understand:
Why it hurts (cause)
What’s safe (prevent aggravation)
What to avoid short-term (recover as fast as possible)
A better understanding provides you with clarity, confidence and a road-map.
Manual therapy
Used to:
Reduce protective muscle tension
Improve spinal and hip movement
Calm the nervous system
- Correct poor lower limb alignment
Our physiotherapists are highly skilled at various hands-on therapy techniques such as dry needling, muscle release, joint mobilisation and cupping.
Manual therapy is great at fast pain relief so you can get moving as soon as possible.
Targeted exercise
This may include:
Spinal mobility
- Foot and ankle alignment
Hip and glute strength
Core control and strength
Nerve mobility (not aggressive stretching)
Exercises are selected based on your presentation, appropriate for your level and customised to your needs.
Gradual return to normal activity
Movement is medicine and plays an important role in pain relief, promoting tissue healing and overall function. The key is the right dose.
If you don’t use it, you lose it!
What about stretching for sciatica?
Stretching can help or it can make things worse.
If the nerve is irritated, aggressive stretching often flares symptoms.
This is why assessment matters combined with guidance from your physiotherapist.
How long does sciatica take to settle?
Typical recovery timelines:
Mild cases: 2–6 weeks
Moderate cases: 6–12 weeks
Long-standing cases: longer, but still very treatable
Early, active management shortens recovery significantly and prevents chronic low back pain.
When should you see a physio?
You should book in if:
Leg pain lasts more than a few days
Pain is worsening
You have tingling, numbness or weakness
Sitting or work is becoming difficult
Early care prevents chronic issues and secondary compensations which can cause other issues in the future.
Why physiotherapy works for sciatica?
Physiotherapy doesn’t just calm symptoms.
It addresses:
The mechanical driver
Movement habits
Strength deficits
Nerve sensitivity
That’s how you get lasting relief, not repeat flare-ups.
Do I need surgery for sciatica?
In most cases, no.
Around 90–95% of people with sciatica improve without surgery using conservative treatment such as physiotherapy, education and graded exercise.
Surgery is usually only considered when:
Severe leg pain persists despite several months of appropriate treatment
There is progressive muscle weakness in the leg or foot
There is loss of bladder or bowel control (this is rare and urgent)
Even when scans show a disc bulge or herniation, many people recover fully without surgery.
If your doctor suggests for you to see a surgeon before trying conservative treatment, make sure to get a second opinion.
Surgery is the last resort, not the first step.
FAQs
What is the fastest way to relieve sciatica pain?
The fastest relief usually comes from reducing nerve irritation, not forcing it to stretch.
This means short-term load modification, gentle movement, targeted exercises and manual therapy. Lying down for days or stretching aggressively often delays recovery.
Is walking good or bad for sciatica?
Walking is usually very helpful for sciatica when kept within tolerance.
Short, frequent walks are better than long walks that flare up your symptoms. If leg pain increases or lingers after walking, the dose needs adjusting.
Can sciatica go away on its own?
Yes, many cases do settle over time.
However, without proper guidance, sciatica often keeps recurring and you will likely develop compensatory movement patterns that can cause other issues.
Physiotherapy helps speed up recovery and reduces the risk of flare-ups returning.
Can sciatica cause foot or calf pain?
Yes. Because the sciatic nerve travels down the leg, symptoms can be felt in the calf, ankle or foot, even if the problem starts in the lower back or hip.
Next Steps: get your sciatica sorted
If sciatica is affecting your work, sleep or training, don’t wait it out.
A proper assessment can:
Identify the exact cause
Reduce pain safely and quickly
Get you back to moving with confidence
Early treatment means faster recovery and better results.
