Low Back Pain Management, Lumbar Disc Disease Management

  • Management
  • General Measures
  1. Ice or heat applied to affected area
    1. Initial interval: 20-25 minutes per hour
    2. Later interval: three times daily
  2. Position of comfort
    1. Flexion relieves pressure on Posterior Columns
    2. Extension relieves pressure on anterior columns
  3. Body mechanics
    1. Ease transfers out of bed
    2. Ease moves to chair, car, toilet, and bathtub
  4. 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
  5. Massage
    1. No affect on pain, functional status or mobility
  6. 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
    5. Little added benefit in early referral for Acute Low Back Pain
      1. Fritz (2015) JAMA 314(14): 1459-67 [PubMed]

  2. 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
  3. Muscle relaxants
    1. Efficacy studies
      1. Reduces Acute Low Back Pain
      2. Does not impact outcome
      3. No benefit over Placebo in chronic Low Back Pain
    2. Entire class acts centrally and causes sedation
    3. Greatest benefit may be at night to assist sleep
    4. Valium does not add benefit over Naprosyn alone for Low Back Pain
      1. Friedman (2017) Ann Emerg 70(2): 169-76 +PMID: 28187918 [PubMed]
  4. Systemic Corticosteroids (variable evidence)
    1. Variable proven benefit over NSAIDs and increased risk of adverse effects
    2. May reduce radicular pain
    3. Some studies have suggested treating for seven day course on fast taper
    4. Some studies demonstrating efficacy have used a 2 week taper (Prednisone 60, 40 then 20 mg)
      1. However most studies show no significant benefit in Acute Low Back Pain due to Herniated disc
      2. Goldberg (2015) JAMA 313(19):1915-23 +PMID:25988461 [PubMed]
