Herniated disc, explained
Disc Herniation
Shift Spinal Health · Adelaide
A herniated disc sounds alarming, and it is often less dramatic than it feels. Here is what it actually is, how it differs from a bulge, and how we approach it at Shift.
What It Is
What a disc herniation actually is.
Between each of the bones in your spine sits a disc, with a tough outer wall and a softer centre. A disc herniation happens when that outer wall weakens and some of the inner material pushes outward, sometimes pressing on a nearby nerve. It can happen in the lower back or in the neck.
Whether it causes symptoms, and what those symptoms are, depends on where it is and whether a nerve is involved. This is worth knowing: plenty of disc herniations show up on scans in people who have no pain at all. That is why a scan is only ever part of the picture, and why a proper assessment matters more than an image on its own.
Clearing Up The Terms
Bulge, herniation, slipped disc.
These words get used interchangeably, which causes a lot of confusion. Here is the plain-language version.
Disc bulge
The disc wall stays intact but pushes outward more broadly, a bit like a tyre under load. Often causes no symptoms, and sometimes contributes to back or neck pain.
Disc herniation
The softer inner material pushes through or past the disc wall. A herniation is more likely than a bulge to press on a nerve, though it does not always cause symptoms either.
Slipped disc
An everyday term rather than a medical one. Discs do not actually slip out of place; people usually mean a bulge or a herniation when they say it.
What It Feels Like
Symptoms depend on where it is.
If a herniation irritates a nerve root in the lower back, it can refer pain, numbness or tingling into the buttock and down the leg. That pattern is one of the common causes of sciatica. A herniation in the neck can refer symptoms into the shoulder, arm or hand.
Not every herniation behaves this way. Some cause mostly local back or neck pain and stiffness, and some cause nothing noticeable at all. Working out what your symptoms are actually telling us is the point of the assessment.
Knowing The Difference
When to seek urgent care.
Most disc problems are not an emergency. A small number of signs mean you should seek urgent medical care straight away rather than wait for an appointment.
Seek emergency care now if you have
- Loss of control of your bladder or bowel
- Numbness around the saddle area (inner thighs, groin, buttocks)
- Rapidly worsening weakness in one or both legs
These can signal a rare but serious problem that needs immediate assessment at a hospital. If in doubt, treat it as urgent.
The Evidence
Most herniations do not need surgery.
For most people, a disc herniation settles without an operation. The widely accepted path is to work through conservative, non-surgical care first, and research shows that many herniations improve over time, with some reducing on their own. Surgery is generally reserved for cases that do not respond, or where there are progressive nerve signs.
That is the space Shift works in: structured, non-surgical care delivered as a program you build over time. And if surgery ever does look like the right option for you, we will say so and refer.
How We Work
The Shift approach to disc herniation.
Care at Shift is structured and active. It starts with understanding your problem, then works on both settling symptoms and rebuilding the support around your spine.
Assess first
Everything starts with a Spinal Health Assessment. A clinician examines your spine, talks through your history and goals, reviews any imaging you have, and works out what is actually driving your symptoms.
Chiropractic care and Smart Decompression
Depending on what suits your case, your care may involve chiropractic care, the MT Core Smart Decompression, or both. The MT Core is a computer-guided table Shift was the first in South Australia to bring here. More on Smart Decompression.
Build strength alongside
Care here is active. Guided rehabilitation is part of the same program, phased in as you progress, using our rehab gym and app so the work continues between visits.
Track with the Shift Score
Your progress is measured with the Shift Score and re-checked every 4 weeks, so change is something you can see rather than take on faith.
Is It For You
Who this suits.
Our structured program, Rebuild, is built for people who:
- Have a persistent or complex disc problem, not a one-off tweak
- Have already tried other things without lasting change
- Are considering surgery, or want a genuine alternative to explore first
- Want to take an active part in their recovery, not just be treated
- Prefer a clear, structured path over open-ended visits
Not everyone who comes in needs the full program. Chiropractic care and the MT Core Smart Decompression are also available for more general back and neck problems, once a clinician has confirmed at your assessment that they are safe and appropriate for you.
Questions
Disc herniation, answered.
Yes. Shift Spinal Health provides assessed, non-surgical care for disc herniation at two Adelaide clinics, Allenby Gardens and Malvern. Depending on your assessment, care may involve chiropractic care, the MT Core Smart Decompression, or both. Everything starts with a Spinal Health Assessment.
For most people a herniated disc does not need surgery. The usual approach is conservative, non-surgical care first, and research shows many herniations settle over time, with some reducing on their own. Surgery is generally reserved for cases that do not respond or that involve progressive nerve signs.
With a bulge, the disc wall stays intact but pushes outward more broadly. With a herniation, the softer inner material pushes through or past the disc wall. A herniation is more likely than a bulge to press on a nearby nerve, though neither always causes symptoms.
No. A herniated disc is a physical change in the disc. Sciatica is a set of symptoms, leg pain along the sciatic nerve, that a lumbar herniation can cause when it irritates a nerve root. One is a cause, the other is an effect.
An MRI is not required to begin, but it is helpful for a suspected herniation because it can confirm the diagnosis and show the level involved. If you do not have one, we can guide you on how to get one.
