When Is Lower Back Pain Serious and When Should You See a Physio?
When Is Lower Back Pain Serious and When Should You See a Physio?
Short answer: Most lower back pain is not serious and settles within 6 weeks. Serious lower back pain includes red flag signs like numbness in the groin, loss of bladder or bowel control, unexplained weight loss, fevers, or pain following a fall or accident. If your back pain has lasted more than 2 weeks, is worsening, or is stopping you doing everyday activity, see a physio in Sydney (Bexley North or Marrickville) sooner rather than later.
What counts as lower back pain?
Lower back pain is any pain, stiffness or ache in the region between your lower ribs and the top of your buttocks. It affects roughly 4 million Australians at any one time.
Most cases are what we call non specific mechanical low back pain. That means the pain comes from muscles, joints or discs of the lumbar spine, and no single sinister cause is behind it.
Around 90 percent of lower back pain settles within 6 weeks with the right advice, movement and physiotherapy. The rest need a more thorough assessment to rule out red flags.
When is lower back pain a red flag?
Serious lower back pain is uncommon but important to catch early. See your GP or emergency department immediately if you have any of the following.
- Numbness in the groin or saddle area (possible cauda equina syndrome)
- Loss of bladder or bowel control
- Sudden weakness in the legs
- Back pain after a serious fall, car accident or contact injury
- Unexplained weight loss, night sweats or fevers alongside back pain
- A history of cancer with new back pain
- Severe back pain at night that will not settle with any position
Aside from those red flags, most lower back pain can be assessed and treated by a Sydney physio without any imaging.
Do I need a scan for my back pain?
Short answer: Usually no. Australian and international guidelines specifically recommend against routine imaging for lower back pain in the first 4 to 6 weeks unless red flags are present.
Scans regularly show disc bulges, degeneration or arthritis that do not match the pain and are found in people with no back pain at all. Chasing the scan often leads to fear and unhelpful treatments.

When should you see a physio for lower back pain?
See a physio in Sydney if any of these apply:
- Your back pain has lasted more than 2 weeks and is not settling
- Pain is stopping you working, sleeping or exercising
- Pain radiates down one or both legs (possible sciatica)
- You have had repeated flare ups of back pain over the last 12 months
- You are pregnant or postnatal with back pain
- You have a claim through NDIS, WorkCover, CTP, DVA or an EPC plan from your GP
- You want to prevent your first back pain episode becoming a chronic problem
Early, targeted physiotherapy in the first 2 to 4 weeks is one of the strongest predictors of a quick full recovery from lower back pain.

How long does lower back pain take to settle?
Short answer: Most acute lower back pain episodes settle within 2 to 6 weeks with the right plan. Chronic lower back pain (lasting more than 12 weeks) takes longer but consistently improves with structured physiotherapy.
- Days 1 to 3: Keep moving in comfortable ranges. Ice or gentle heat can help. Avoid full bed rest.
- Week 1 to 2: Symptoms usually start to ease. Book a physio if it is not improving.
- Week 2 to 6: Progressive loading and strengthening. Return to normal activity.
- Week 6 plus: If pain lingers, we work on chronic pain drivers including sleep, stress and deconditioning.

6 mistakes that make lower back pain worse
- Bed rest for days on end. Prolonged rest makes acute back pain worse, not better.
- Chasing scans as your first step. Imaging without red flags creates fear and rarely changes treatment.
- Endless stretching of the painful spot. Most lower backs need more control, not more flexibility.
- Ignoring it for months. Untreated back pain has a 50 percent chance of becoming chronic within 12 months.
- Only relying on pain medication. Painkillers mask the signal without addressing what is driving the pain.
- Assuming you need surgery. Most lower back pain, including with sciatica, resolves without surgery.
⚠️ Seek urgent care if
- You have any of the red flag signs listed above
- Back pain with fever, chills or feeling systemically unwell
- Weakness or numbness that is progressing
