Treatment for Sciatica
The first-line treatment for sciatica should follow a risk-stratified approach using the STarT Back tool to categorize patients into low, medium, or high risk for persistent disabling pain, with management including non-pharmacologic therapies (exercise, physical therapy) and pharmacologic options (NSAIDs as first-line medication), reserving surgery for specific indications such as progressive neurological deficits or persistent symptoms despite 6-12 weeks of conservative management. 1
Risk Assessment and Management Approach
Initial Risk Stratification:
- Use the STarT Back tool within 2 weeks of symptom onset 1
- Categorize patients into:
- Low risk → Self-management with appropriate pain relief and education
- Medium risk → Physiotherapy with patient-centered management plan
- High risk → Comprehensive biopsychosocial assessment and physiotherapy
Document Red Flags requiring urgent evaluation:
- Age >50 or <20 years
- History of cancer, unexplained weight loss
- Fever, chills, recent infection
- Saddle anesthesia, bladder/bowel dysfunction
- Progressive neurological deficits 1
Conservative Treatment
Non-Pharmacologic Options (First-Line)
- Exercise therapy
- Multidisciplinary rehabilitation
- Acupuncture
- Mindfulness-based stress reduction
- Tai chi, yoga
- Motor control exercise
- Cognitive behavioral therapy
- Spinal manipulation 1
Pharmacologic Treatment
- First-line: NSAIDs (moderate-quality evidence) 1
- Alternatives:
- Skeletal muscle relaxants (moderate-quality evidence)
- Acetaminophen for those who cannot take NSAIDs
- Neuropathic pain medications (gabapentin, pregabalin) if radicular component is prominent 1
- Second-line: Tramadol or duloxetine 1
- Last resort: Opioids only after failure of other treatments and only if benefits outweigh risks 1
The older recommendation of complete bed rest for 2 weeks 2 is now considered outdated, as current guidelines emphasize maintaining activity as tolerated.
Diagnostic Considerations
- Imaging is not recommended for nonspecific low back pain
- Consider imaging only for:
- Severe or progressive neurological deficits
- Suspected serious underlying conditions
- Persistent symptoms with radiculopathy if surgery or epidural injection is being considered 1
- MRI is preferred over CT as it better visualizes soft tissues and avoids radiation exposure 3
Surgical Intervention
Surgery should be considered only in specific circumstances:
- Cauda equina syndrome (emergency)
- Progressive neurological deficits
- Motor deficit greater than grade 3
- Persistent radicular symptoms despite 6-12 weeks of conservative treatment
- Intractable pain despite comprehensive conservative management 1
Lumbar discectomy is the established procedure for primary disc herniation with radiculopathy when conservative management fails. Importantly, lumbar fusion is NOT recommended as a routine treatment following primary disc excision 1.
Special Populations
- Elderly patients: Slower progression of exercise intensity and careful medication management due to higher risk of medication side effects 1
- Cardiovascular disease or renal impairment: Special attention with NSAID use 1
- Patients with Ehlers-Danlos Syndrome: May benefit from multidisciplinary approach involving rheumatology, cardiology, or nephrology 1
Follow-Up Protocol
- Close follow-up within 48-72 hours to reassess symptoms
- Document specific timeframe for follow-up and criteria for earlier reassessment
- If symptoms persist beyond 6 weeks despite appropriate management, consider additional imaging or specialist referral 1
Clinical Course and Prognosis
The natural history of sciatica is generally favorable, with most pain and related disability improving within 2-4 weeks with or without treatment 3. This positive prognosis should be communicated to patients to provide reassurance.
Common Pitfalls to Avoid
- Rushing to imaging before adequate conservative management trial (6-8 weeks)
- Overreliance on opioid medications
- Neglecting psychosocial factors, which are stronger predictors of outcomes than physical examination findings or pain severity
- Recommending routine fusion following primary disc excision
- Failing to recognize true sciatica (radicular pain) versus referred pain from the lower back 4
