Clinical Insight

InstantMed Clinical Team
AHPRA-registered medical team · Reviewed 2026-03
Lower back pain is the single most common musculoskeletal complaint in general practice, and it is both over-investigated and under-treated. Over-investigated because imaging is ordered far too early and too often - MRI findings of disc degeneration, bulges, and protrusions are present in up to 50% of pain-free adults. These findings often cause unnecessary alarm and can lead patients toward invasive treatments they don't need. Under-treated because the most effective interventions - staying active, targeted exercise, and cognitive approaches to pain management - are underutilised compared to passive treatments. The vast majority of lower back pain is 'mechanical' (muscle/ligament strain, normal disc wear) and resolves within 6 weeks. My role in telehealth assessment is triaging: ruling out the rare serious causes (cauda equina, fracture, infection, cancer) and providing practical guidance for the far more common mechanical pain.
Treatment
TreatingLowerBackPain
Evidence-based management of lower back pain prioritises active treatment over passive rest. The RACGP guidelines recommend paracetamol and NSAIDs as first-line analgesics, combined with physiotherapy-directed exercise. Opioids are not recommended for non-specific low back pain due to poor efficacy and addiction risk. For chronic lower back pain (greater than 3 months), duloxetine has PBS-listed evidence, and multidisciplinary pain programmes have the strongest long-term outcomes data.
Paracetamol
Panadol, Panamax
Class:Analgesic
Typical dose:500-1000mg every 4-6 hours; maximum 4g per 24 hours
PBS:Available OTC without prescription
- First-line analgesic; evidence for lower back pain is modest but risk profile is excellent
- Regular dosing (not just as needed) provides better control during acute flares
- Avoid in significant liver disease or high alcohol intake
Naproxen
Naprosyn, Inza
Class:NSAID
Typical dose:500mg twice daily with food
PBS:PBS listed; $25.00 general / $7.70 concession (PBS, 2026)
- NSAIDs have stronger evidence than paracetamol for lower back pain with inflammatory component
- Twice-daily dosing supports compliance; take with food
- Avoid in cardiovascular disease, peptic ulcer, renal impairment; use shortest effective course
Duloxetine
Cymbalta, Duloxetine Sandoz
Class:Serotonin-norepinephrine reuptake inhibitor (SNRI)
Typical dose:30mg daily for 1 week, then 60mg daily; titrate to response
PBS:PBS listed for chronic low back pain; $25.00 general / $7.70 concession (PBS, 2026)
- Recommended by RACGP guidelines for chronic low back pain (greater than 3 months) when NSAIDs are insufficient or contraindicated
- Modest but consistent effect on pain and function; takes 2-4 weeks for full effect
- Taper slowly on cessation to avoid discontinuation syndrome; do not stop abruptly
- A telehealth consult can assess suitability for duloxetine initiation

Specialist referral: Refer to a physiotherapist for exercise prescription as first-line. Refer to a spinal specialist or neurosurgeon if cauda equina symptoms develop (bladder/bowel changes, bilateral leg weakness, saddle numbness), if MRI shows significant disc herniation with progressive neurology, or if pain persists beyond 3 months without improvement. Pain clinic referral for chronic refractory pain.
Lower Back Pain in Australia
Lower back pain is the leading cause of disability in Australia and worldwide (AIHW)
1 in 6 Australians (4.0 million people) report back problems
Back pain costs the Australian economy an estimated $4.8 billion per year in direct healthcare and lost productivity
MRI findings of disc degeneration are found in 37% of pain-free 20-year-olds and 96% of pain-free 80-year-olds - they are a normal part of ageing
Recovery
Whattoexpect
Typical recovery timeline and return-to-work guidance for most patients.
Typical recovery
Acute episode: significant improvement within 2-4 weeks, 90% resolve within 6 weeks. First 48-72 hours are usually the worst. Some residual stiffness may linger for several weeks.
Return to work
Desk work: 1-3 days with ergonomic adjustments. Physical labour: 1-3 weeks with graduated return. Staying off work completely for extended periods is associated with worse outcomes - modified duties are better than no work.
When to reassess
Seek urgent assessment for bladder/bowel control changes, groin numbness, progressive leg weakness, or severe pain after trauma. Otherwise, reassess if pain has not improved after 4-6 weeks of appropriate self-management.
Self-Care
ManagingLowerBackPainathome
Evidence-based tips to support your recovery alongside medical treatment.
Stay gently active - walking is the single best activity for lower back pain recovery
Apply heat for chronic/stiff pain or ice for acute/inflamed pain - 20 minutes on, 20 off
Avoid prolonged sitting or standing - change position every 30 minutes
Sleep on your side with a pillow between your knees, or on your back with a pillow under your knees
Paracetamol and ibuprofen together provide more effective relief than either alone
Once the acute episode settles, start core strengthening exercises - this is the best prevention for recurrence
FAQ
CommonquestionsaboutLowerBackPain
Answers to the most common questions from patients.
Usually not. Imaging is only recommended if symptoms persist beyond 6 weeks, are worsening, or if there are 'red flag' features. Most lower back pain improves without imaging, and MRI findings like disc bulges are extremely common even in pain-free people.
Keep moving. Bed rest beyond 1-2 days actually slows recovery. Gentle walking, swimming, and stretching are the best activities. Avoid movements that significantly worsen pain, but don't stop all activity.
Most acute lower back pain improves significantly within 2-4 weeks. 90% of episodes resolve within 6 weeks. Some people experience recurrent episodes - strengthening exercises help prevent these.
Yes. Lower back pain is the leading cause of work-related disability. A certificate is appropriate, especially for physical work. We can also recommend modified duties or a graduated return to work.
