Management of Chronic Lower Back Pain in Relatively Healthy Adults
Begin with exercise therapy combined with acetaminophen or NSAIDs, avoiding interventional procedures and imaging unless red flags are present. 1, 2
First-Line Treatment Approach
Start with nonpharmacologic therapy as the foundation:
Exercise therapy is the cornerstone of treatment and demonstrates moderate efficacy for pain relief (10-20 points on a 100-point scale) and functional improvement. 1, 3 No single exercise type is superior to another—walking, stretching, strengthening, or group programs all provide benefit. 4
Provide reassurance and education that chronic low back pain typically improves with continued activity rather than rest, and that remaining active prevents deconditioning and worsening disability. 2, 3 Bed rest should be completely avoided as it leads to muscle atrophy and slower recovery. 3
Add cognitive-behavioral therapy if pain persists, as it provides moderate benefits (10-20 points on a 100-point pain scale) and helps prevent chronic disability. 1, 3
For pharmacologic therapy:
Acetaminophen (up to 3000 mg/day) is the safest first-line option, particularly in older adults, despite being slightly less effective than NSAIDs. 2
NSAIDs provide superior pain relief but require careful consideration of cardiovascular, renal, and gastrointestinal risks. 1, 2 Use ibuprofen 400 mg every 4-6 hours (maximum 3200 mg/day) or naproxen at the lowest effective dose for the shortest duration. 5
Second-Line Nonpharmacologic Options
If exercise and first-line medications provide insufficient relief, add:
Spinal manipulation provides moderate benefits (10-19 points on a 100-point pain scale) and is remarkably safe with serious adverse events occurring in less than 1 per 1 million visits. 1, 6 Effects are comparable to physical therapy and exercise. 1
Massage therapy shows similar efficacy to other noninvasive interventions for chronic low back pain. 1
Acupuncture demonstrates fair evidence of effectiveness, superior to sham acupuncture for chronic pain. 1
Mind-body interventions including yoga, tai chi, and mindfulness-based stress reduction show moderate evidence of benefit. 1
Second-Line Pharmacologic Options
When first-line medications are inadequate:
Duloxetine (30 mg daily, titrating to 60 mg daily) is the preferred second-line agent for chronic low back pain. 1, 2
Tricyclic antidepressants may provide pain relief but require caution in older adults due to anticholinergic effects (confusion, falls). 1, 2
Intensive Interventions for Refractory Cases
Multidisciplinary rehabilitation combining physical therapy, psychological interventions, and education shows moderate to large benefits and is particularly effective for reducing work absenteeism. 1, 3
Refer to multidisciplinary pain management when pain persists despite optimized first-line and second-line therapies. 2
Critical Interventions to AVOID
The 2025 BMJ guideline issues strong recommendations AGAINST these procedures for chronic axial spine pain: 2
- Radiofrequency ablation of joints
- Epidural injections (local anesthetic, steroids, or combination)
- Joint-targeted injections (local anesthetic, steroids, or combination)
- Intramuscular injections of local anesthetic
These interventions lack evidence of benefit and should not be offered. 2
Imaging and Red Flag Assessment
Do NOT routinely obtain imaging for nonspecific chronic low back pain, as findings are often nonspecific and do not improve outcomes. 2, 3
Obtain MRI or CT only when: 3
- Progressive neurological deficits are present
- Cauda equina syndrome is suspected
- Infection or malignancy is suspected
- Symptoms persist in surgical candidates
Opioid Considerations
Opioids should NOT be first-line or routine therapy for chronic low back pain. 1
Consider opioids only after documented failure of all other therapies and when potential benefits clearly outweigh risks. 2
Before initiating opioids, conduct thorough risk assessment including screening for substance use disorder, mental health conditions, and concurrent sedative use. 2
Common Pitfalls to Avoid
Avoid passive physical therapies (interferential therapy, traction, ultrasound, lumbar supports, TENS) as they lack evidence of effectiveness. 1, 2
Avoid systemic corticosteroids as they show no greater efficacy than placebo. 3
Do not prescribe prolonged bed rest as it worsens outcomes through deconditioning. 3
Avoid overreliance on imaging findings to guide treatment, as degenerative changes are common in asymptomatic individuals and do not correlate with pain severity. 3
