The shooting pain starts somewhere around your lower back, cuts through your glute, and fires down one leg. Some days it’s a dull ache. Other days it stops you mid-lift. You’ve tried rest. Maybe some anti-inflammatories from your GP. It calms down for a week or two, then a long drive or a heavy morning at work brings it straight back.
If that pattern sounds familiar, you’re not imagining it — and you haven’t just “done something” to your back. The problem is that sciatica treatment that only targets pain (rather than the underlying cause) almost never holds. This article explains why sciatica keeps returning for people in physically demanding jobs, what’s actually driving the nerve irritation, and how physio combined with gym-based rehab changes that pattern.
Why Sciatica Keeps Coming Back
Rest and anti-inflammatories reduce the flare-up. They don’t fix what’s irritating the sciatic nerve in the first place.
The sciatic nerve runs from your lower spine, through your glute, and down each leg. It’s the longest nerve in the body, and it passes through a corridor of joints, discs, and muscles that can all compress or load it. When that compression eases off (usually with rest), the pain settles. But if the structural issue remains — a disc putting pressure on a nerve root, a tight piriformis, a spine that’s lost its supporting strength — the next heavy shift or long drive recreates the same load, and the pain returns.
For tradies, warehouse workers, and delivery drivers, the physical demands of the job don’t disappear during recovery. So the question isn’t just “how do I get the pain down?” It’s “what needs to change so I can keep working without this happening every few weeks?”
What’s Actually Irritating the Sciatic Nerve
Sciatica is a symptom, not a diagnosis. The shooting pain down your leg is the nerve’s response to being compressed, stretched, or chemically irritated. There are several structures that can do this, and they behave differently under load:
Disc Bulge or Herniation
The discs that sit between your vertebrae act as shock absorbers. Repeated bending, twisting, and heavy lifting can cause the outer wall of a disc to bulge outward, pressing against nearby nerve roots. A disc bulge at L4/L5 or L5/S1 — the two lowest levels of the lumbar spine — is the most common culprit in work-related sciatica. You’ll often notice symptoms are worse after long stints of sitting (sustained load) or first thing in the morning.
Spinal Stenosis
Stenosis refers to a narrowing of the spinal canal or the small openings where nerve roots exit. It tends to be more common as people get older, and it’s often aggravated by standing or walking rather than sitting. Unlike disc-related sciatica, stenosis symptoms may ease when you bend forward or sit down, because that position opens the canal slightly. Your physio will test for this specifically during assessment.
Piriformis Syndrome
The piriformis is a muscle that runs from your sacrum to the top of your thigh bone. In some people, the sciatic nerve passes directly through it. When the piriformis tightens — often from prolonged sitting, driving, or imbalanced hip mechanics — it can clamp down on the nerve. This type of sciatica doesn’t originate from the spine at all, which is one reason a proper assessment matters before deciding on treatment direction.
What a Physio Assessment Actually Looks at
The goal of the initial assessment isn’t just to confirm that it’s sciatica — it’s to work out which structure is causing the problem and why it’s still there.
Your physiotherapist will test nerve tension (straight leg raise, slump test), assess spinal movement, and check the strength and control of the muscles responsible for stabilising your lower back and pelvis. They’ll also ask about your work, how long you’re on your feet, whether sitting or standing makes it worse, and how the pain behaves across a typical day.
That last part matters more than people expect. Sciatica from a disc bulge and sciatica from piriformis syndrome often feel similar, but the triggers are different and the rehab approach differs accordingly. Treating the wrong one won’t get you better, and it can add weeks to your recovery. At Your Story Physio, the initial 40-minute appointment gives us time to go through this properly before any treatment starts.
Nerve Mobilisation: Getting the Nerve Moving Freely Again
When a nerve has been under compression for a sustained period, it can become sensitised and lose its ability to glide smoothly through the surrounding tissue. This is sometimes called neural tension, and it means the nerve itself has become part of the problem, not just the structure irritating it.
Nerve mobilisation (or neural flossing) involves specific, controlled movements that ‘slide’ the nerve through its pathway without compressing it further. These techniques are prescribed carefully based on the assessment findings. The nerve needs to be loaded just enough to restore mobility without provoking a flare-up. Done correctly, most people notice an improvement in the quality and distribution of their pain within a few sessions.
This is hands-on work done in the treatment room, but the real gains come from pairing it with the next stage.
Gym Rehab: Why Strength Is the Missing Piece for Sciatica Treatment
Manual therapy relieves pain. Strength work prevents it from returning.
Most people with recurring sciatica have identifiable weaknesses in the muscles that protect the lower spine from load: the deep core stabilisers, the glutes, and the hip abductors. When these muscles aren’t doing their job, the spine absorbs more of the impact from lifting, carrying, and prolonged standing. The nerve ends up compressed again.
At Your Story Physio, physio appointments include supervised gym sessions in our on-site rehab gym. This isn’t generic gym work. The exercises are chosen based on your assessment findings and adjusted as you progress. A typical program for sciatica rehab builds through a few phases:
- Core stability: Re-activating the deep stabilisers (transverse abdominis, multifidus) that support the lumbar spine under load
- Glute and hip strengthening: Hip thrusts, single-leg work, and clamshell progressions to restore the load-sharing that reduces pressure on the disc and nerve root
- Functional loading: Gradually reintroducing the bending, lifting, and carrying patterns that your job requires, with proper technique built in from the start
For people managing a WorkCover claim, gym rehab is an important part of the return-to-work process. It documents your capacity, builds the physical tolerance for full duties, and reduces the risk of re-injury once you’re back on the job.
When This Approach May Not Be Enough
Physio and gym rehab work well for the majority of sciatica presentations, but there are some situations where additional investigation or medical input is needed first.
If you’re experiencing bladder or bowel changes alongside your leg pain, numbness in the inner thigh or groin area, or weakness in the foot and ankle that appeared suddenly, you should seek medical review promptly. These can be signs of cauda equina syndrome, which requires urgent assessment.
Sciatica related to a significant disc herniation causing severe nerve compression may also need imaging or specialist review before a rehab program begins. Your physio will tell you clearly if they think a scan or referral is warranted after your initial assessment. Most people with long-standing, flare-prone sciatica — the kind that comes and goes with work — are suitable for physio-led rehab.
Sciatica treatment: Your Questions Answered
| Question | Answer |
|---|---|
| What is the most effective sciatica treatment? | The most effective sciatica treatment depends on the cause. Physiotherapy that combines hands-on assessment, nerve mobilisation, and supervised gym rehab targeting core stability, glute and hip strength tends to produce lasting results. Rest and anti-inflammatories reduce symptoms temporarily but do not address the structural cause. |
| Why does my sciatica keep coming back? | Sciatica that keeps returning usually means the root cause has not been treated. Common causes include disc bulge pressing on a nerve root, piriformis tightness, or spinal stenosis. Without strengthening the muscles that support the spine and reducing the compression on the nerve, flare-ups continue with physical activity. |
| Can a physiotherapist help with sciatic nerve pain? | Yes. A physiotherapist can assess the cause of your sciatic nerve pain, provide manual therapy and nerve mobilisation to reduce symptoms, and prescribe a targeted exercise program to prevent recurrence. For work-related sciatica, physio can also support return-to-work planning under WorkCover. |
| How long does sciatica treatment take? | Most people with flare-prone sciatica notice meaningful improvement within 4 to 6 weeks of consistent physiotherapy and gym rehab. A full program including strength work typically runs 6 to 8 weeks with two sessions per week. Timeline varies depending on the cause and severity. |
| Does WorkCover cover sciatica treatment? | Yes, if your sciatica is work-related and you have an approved WorkCover claim, physiotherapy treatment including gym rehabilitation is generally covered. Your Story Physio provides no-gap WorkCover physiotherapy for approved claims in Sunshine, Victoria. |
| What sciatica exercises help long-term? | Sciatica exercises that provide lasting relief focus on core stability, glute strengthening, and hip control rather than stretching alone. Neural mobilisation exercises also help restore nerve movement. Your physiotherapist will prescribe a specific program based on the cause of your sciatica. |
Getting Ahead of It
Sciatica that keeps returning with each physical demand is not something you have to manage around. For most people in physical jobs, it reflects a correctable combination of nerve irritation and insufficient support from the surrounding muscles. Getting an accurate assessment, then working through hands-on treatment and progressive strength work, breaks that cycle.
If you’ve been told to rest and it hasn’t lasted, it’s worth getting a second opinion from a physio who can look at the full picture. We offer a free phone consultation if you’re not sure where to start.
