It's one of the most common questions we hear: "I've been told I have a disc bulge. Is it safe for me to see a chiro or physio?"
It's a fair question. A disc problem can sound fragile, and if you're dealing with back pain or sciatica, the last thing you want is to make things worse.
The short answer: for most people with a disc herniation, yes. Conservative care from a chiropractor or physiotherapist is a recommended first step for most people without serious warning signs. Here's what the research says, where the evidence is strong, where it's still developing, and how we keep care safe.
Why conservative care comes first
As we covered in our previous article on surgery, most disc herniations improve over time without an operation. A systematic review found that herniated disc material regressed in 96% of sequestrated discs, 70% of extrusions, 41% of protrusions and 13% of bulges, often with the biggest herniations shrinking most.
Because the natural course is usually favourable, clinical guidelines recommend starting with conservative care for most people. Australia's Low Back Pain Clinical Care Standard emphasises education, staying active and self-management, and notes the limited role of imaging, bed rest and surgery for most people with low back pain.
The goal of conservative care isn't just to wait. It's to help you manage pain, stay active and recover function while your body does its work, and to pick up early any signs that you need something more.
What does the research say?
Chiropractic and spinal manipulation
Several studies have looked specifically at people with confirmed disc herniations.
An Italian randomised trial published in The Spine Journal in 2006 compared active spinal manipulation with simulated (sham) manipulation in 102 people with acute back pain, sciatica and an MRI-confirmed disc protrusion. Those who received active manipulation had more days without pain and were more likely to become pain-free. About 28% of the manipulation group became free of local back pain compared with 6% of the sham group, and 55% became free of radiating leg pain compared with 20%. No adverse events were reported.
A smaller Canadian trial published in 2010 included 40 people with sciatica from a disc herniation who had already tried at least three months of other non-surgical care and been referred to neurosurgeons. They were randomly assigned to either microdiscectomy or chiropractic spinal manipulation. At one year, about 60% of those who received manipulation improved to a similar degree as those who had surgery. Those who didn't improve went on to have surgery and did just as well as people who had surgery first.
These results are encouraging, but both trials were relatively small, and more research is needed to confirm the findings.
Physiotherapy and exercise
Physiotherapy, including exercise, manual therapy and education, is recommended in clinical guidelines for people with sciatica.
A 2023 systematic review in the European Spine Journal looked at the research on physiotherapy for sciatica. It found the overall evidence was mixed, largely because many trials were small, varied widely and didn't always use modern physiotherapy approaches. However, the reviewers noted that the most effective programs tended to combine individualised exercise, manual therapy and advice.
In other words, the research supports a tailored, active approach rather than any single "magic" technique.
The honest picture
The evidence for conservative care in disc herniation is promising but not perfect. Studies vary in quality and size, and people with sciatica are a varied group. What we can say with confidence is:
Most people improve over time, and conservative care is the recommended first approach for most
Spinal manipulation, exercise, manual therapy and education all have some supporting evidence
A combined, individualised approach tends to work better than a single technique
Close monitoring matters, so anyone who needs a surgical opinion is referred promptly
Is it safe?
This is the question most people really want answered.
Serious complications from spinal manipulation of the lower back are rare. A systematic review estimated the risk of manipulation causing a worsened disc herniation or cauda equina syndrome in someone with a disc herniation at less than 1 in 3.7 million treatments. A later population-based study from Canada found no evidence that chiropractic care increased the risk of acute disc herniation compared with seeing a GP, suggesting that people who develop a disc herniation often seek care for early symptoms before the herniation is diagnosed.
That said, no treatment is risk-free, and safety comes from good assessment. Before any hands-on care, a thorough examination should check:
Your history and the pattern of your symptoms
Nerve function, including strength, reflexes and sensation
Any red flags that mean you need medical or surgical review instead
It's also important to know that manipulation is only one option. Many people with disc problems do very well with gentler approaches such as mobilisation, soft tissue work, nerve mobility exercises and graded strengthening. Your care should be matched to what you're comfortable with and what your body can handle.
When conservative care isn't the right first step
Some symptoms need urgent medical attention rather than conservative care. Go to the emergency department straight away if you have back or leg pain along with:
New difficulty passing urine, or loss of bladder or bowel control
Numbness in the groin, genitals, inner thighs or around the back passage
Sudden or worsening weakness in one or both legs
Symptoms in both legs that are getting worse
You should also get a prompt medical review if you have progressive weakness, such as foot drop, or severe pain that isn't settling despite appropriate care.
What good conservative care looks like
At Epoch Health, care for disc-related back and leg pain usually includes:
A thorough assessment, including a neurological examination so changes can be tracked over time
Clear explanation of what's going on and what to expect, in plain language
Hands-on care where appropriate, from gentle mobilisation and soft tissue work through to spinal manipulation if suitable and you're comfortable with it
A progressive exercise program to rebuild strength, mobility and confidence
Advice on staying active and modifying activity, rather than bed rest
Regular review of your symptoms and nerve function
Coordination with your GP, including referral for imaging or a surgical opinion if your symptoms aren't improving or change
How our team can help
Our chiropractors, physiotherapists and exercise physiologists work together to give you the right care at the right time. If your symptoms suggest you need a medical or surgical opinion, we'll tell you clearly and work with your GP to arrange it.
Whether you've just been told you have a disc problem or you've been dealing with sciatica for a while, we can help you understand your options and build a plan that fits your life.
