II. Management: General Measures

Set early expectations of positive, gradual response to treatment
Ice or heat applied to affected area
1. Initial interval: 20-25 minutes per hour
2. Later interval: three times daily
Position of comfort
1. Flexion relieves pressure on Posterior Columns
2. Extension relieves pressure on anterior columns
Body mechanics
1. Ease transfers out of bed
2. Ease moves to chair, car, toilet, and bathtub
Stay active
1. Early mobilization activities
  1. Slowly walk every 30 minutes
  2. Consider pool walking
2. Improves outcomes
  1. Speeds recovery
  2. Reduces chronic Disability
  3. Reduces time off work
3. Avoid exacerbating activities
  1. See Return to Work in Lumbar Back Pain
  2. Avoid prolonged standing or sitting
  3. Avoid forward flexion at waist (especially while lifting)
  4. Avoid prolonged bed rest (slows recovery)
    1. If absolutely needed, then limit to no more than 2 days
Physical Therapy
1. See Low Back Rehabilitation
2. See Low Back Muscle Fusion Rehabilitation
3. Consider if no improvement in 2 to 4 weeks
4. Consider traction or inversion table

III. Management: Acute Pain Control

NSAIDs
1. Effective for short-term symptomatic relief
  1. Griffin (2002) Am Fam Physician 65(7):1319-21 [PubMed]

    1. Friedman (2015) JAMA 314(15): 1572-80 [PubMed]
Acetaminophen
1. Dose: 1000 mg orally twice daily (maximum 4000 mg/day)
2. May have less benefit than other measures
  1. Reasonable low risk intervention (if within dosing limits) that may spare Opioids
3. Mixed result in studies
  1. Some studies demontrate relief of musculoskeletal pain with Acetaminophen alone
    1. Gong (2019) Ann Emerg Med 74(4):521-29 [PubMed]

  4. Not more effective than Placebo in Chronic Low Back Pain
    1. Williams (2014) Lancet 384(9954): 1586-96 [PubMed]
Opioids
1. Use sparingly for refractory Acute Low Back Pain
2. Limit to very short course (risk of Opioid misuse, Opioid Abuse and diversion)
3. Patients improve faster without Opioids
4. Not more effective than non-Opioid management in the first 6 weeks of Low Back Pain
  1. Jones (2023) Lancet 402(10398): 304-12 [PubMed]
Lidocaine Patch (4% is over-the-counter)
1. Applied for 12 of every 24 hours
2. May offer transient relief in paraspinous pain
Muscle relaxants or antispasmodics (Benzodiazepines and non-Benzodiazepines)
1. Not recommended due to lack of benefit and increased adverse effects

  3. No significant benefit in Acute Low Back Pain without radiculopathy due to Herniated disc
  4. No significant benefit in spinal stenosis related pain
  5. No benefit in Chronic Low Back Pain
2. Protocols

    1. Balakrishnamoorthy (2015) Emerg Med J 32(7):525-30 +PMID: 25122642 [PubMed]
  2. Some studies have suggested treating for seven day course on fast taper
  3. Some studies demonstrating efficacy have used a 2 week taper (Prednisone 60, 40 then 20 mg)
