Short answer: Can a chiropractor fix a bulging disc? Not in the sense of pushing it back in, and neither can a physio. Many disc problems settle with time and the right conservative care. Chiropractors lean on hands-on care such as adjustments and flexion-distraction; physios lean on exercise. Both are reasonable choices, and many people do well with either.
Can a chiropractor fix a bulging disc?
It's the most common question we hear about discs, so here's a straight answer. A chiropractor can't "pop" a bulging disc back into place. Discs don't work like that. A disc is a tough outer ring with a softer centre, and a bulge is a change in its shape, not a part that has slid out of position.
What a chiropractor can do is assess what's driving your pain, then use care that may reduce irritation around the disc and nerve, help you move with more confidence, and give you a plan you can follow at home. Many people find that's enough to get back to work, sport and sleep while the disc settles.
The same is true for physiotherapy. Neither profession repairs a disc. Both aim to calm things down and get you moving well again.
Bulging, slipped or herniated disc: what's the difference?
These words get used interchangeably, which makes searching for answers confusing.
- Bulging disc: the disc wall flattens and spreads a little beyond its normal edge. Bulges are common, and plenty of people have them on scans without any pain at all.
- Herniated disc: some of the softer inner material pushes through a weakness in the outer ring. This is more likely to irritate a nearby nerve and cause leg pain, pins and needles or numbness.
- Slipped disc: an everyday term, not a medical one. Discs are firmly attached to the bones above and below, so they don't actually slip. People usually mean a bulge or herniation.
The label on a scan matters less than how you present: where the pain goes, what eases it, what aggravates it, and how your nerves are working. That's what a good assessment looks at. You can read more on how spinal disc pain is examined.
Physio or chiro for a bulging disc: how they differ
Physiotherapists and chiropractors are both university-trained and registered with AHPRA. Both assess and manage back and disc problems. The difference is mostly emphasis.
| Chiropractor | Physiotherapist | |
|---|---|---|
| Main focus | The spine, pelvis and nervous system, and how they move | Movement, strength and function across the whole body |
| Typical hands-on care | Spinal adjustments, mobilisation, flexion-distraction tables | Mobilisation, soft tissue work, sometimes manipulation |
| Exercise | Home exercises and rehab advice | Often the centre of care, sometimes supervised in a gym or class |
| Medicare care plan | Eligible | Eligible |
Clinical guidelines for low back pain include spinal manipulation among the options, alongside exercise, education and staying active. In other words, both approaches sit inside mainstream recommendations. Which suits you depends on your presentation and on what kind of care you're likely to stick with. You're free to choose the practitioner who suits you.
When people tend to choose a chiropractor
- You want hands-on care to help you move while your back is sore and guarded.
- Your pain is centred in the low back and pelvis, with or without leg symptoms.
- You'd like a thorough spinal and nerve check, and X-rays if they're warranted.
When people tend to choose a physio
- You prefer an exercise-led approach with more supervised rehab.
- You're also rebuilding after a sporting injury elsewhere in the body.
- You already have a physio you trust and like how they work.
Plenty of people use both at different stages. There's no rule that says you must pick one forever.
Disc pain and the nervous system
A bulge on a scan and the pain you feel aren't the same thing. Pain is produced by your nervous system, which is one reason two people with similar scans can feel very different. Chiropractors pay close attention to that side of things. When a low back segment is sore and guarded, the brain can change how it controls it: the deep muscles tighten, the segment moves less, and the brain gets patchier information back. Chiropractors call this a vertebral subluxation.1
Research is starting to look at the brain in people with disc problems. An independent 2026 review of 10 brain-imaging studies in people with disc herniation or chronic low back pain reported changes in prefrontal and default-mode brain networks after spinal manipulation.2 It's early science, and it doesn't mean an adjustment changes the disc.

What is flexion-distraction?
Flexion-distraction is a gentle, rhythmic, table-assisted technique. You lie face down on a specialised table and the chiropractor guides the lower section of the table through a slow, controlled movement while keeping a hand on the area being worked on. It's commonly used for disc and nerve-related low back pain.
Many people with sore, irritable discs find it more comfortable than they expected, because the movement is controlled and can be scaled to what your back will tolerate. We use a flexion-distraction table at MPCC, and whether it's right for you depends on what your check shows.
Can a chiropractor make a herniated disc worse?
It's a fair question, and you deserve an honest answer. Any hands-on care, from chiropractic to physiotherapy to massage, can stir up symptoms for a day or two. Some people feel sore after a visit. Serious harm is rare, but it isn't zero, which is why careful assessment comes first.
Before any care, a chiropractor should check your reflexes, muscle strength and skin sensation, and look at how your back and legs respond to movement. Those findings guide what's done, how firmly, and whether a technique like flexion-distraction is a better fit than a manual adjustment. If your nerve signs change, care changes too. You can also read about the side effects of chiropractic care.
How we approach disc problems at MPCC
We don't guess, and we don't treat a scan report. Here's what happens.
- New patient appointment (30 to 40 minutes). Your story, posture pictures, and a thorough chiropractic, orthopaedic and neurological check of your spine, joints and nerves. If your history and check point to them, we'll refer you for X-rays, and the imaging clinic we refer to bulk bills X-rays our chiropractors request.
- Report of findings appointment. What we found, in plain English, and what we'd do. Whether we can help, and if we can't, we'll tell you straight.
- Care, if it suits you. Depending on what we find, that may include specific adjustments, flexion-distraction, and exercises to take home.
Whether you're adjusted on your first visit is up to the clinical judgement of your chiropractor. With an irritable disc, more testing often comes first. Learn more on our disc bulge page or see what to expect as a new practice member. No referral is needed to book.
