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

Management
Acute Pain Control

NSAIDs
1. Effective for short-term symptomatic relief
  1. Griffin (2002) Am Fam Physician 65(7):1319-21 [PubMed]
2. Opioid Analgesics and Muscle relaxants do not offer significant additional benefit
  1. Naproxen alone was as effective as when combined with an Opioid or Cyclobenzaprine
    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]
  2. Some studies demonstrate adjunctive benefit when combined with NSAIDs
    1. Bijur (2021) Ann Emerg Med 77(3):345-56 [PubMed]
  3. Some studies show little benefit in decreased pain and increased function in Acute Low Back Pain
    1. Machado (2015) BMJ 350:h1225 [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
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
  1. Cashin (2021) BMJ 374: n1446 [PubMed]
2. Efficacy studies
  1. May reduce Acute Low Back Pain
  2. Does not impact outcome
  3. Minimal benefit over NSAIDs alone
  4. No benefit over Placebo in Chronic Low Back Pain
3. Entire class acts centrally and causes sedation
  1. Greatest benefit may be at night to assist sleep
4. Valium does not add benefit over Naproxen alone for Low Back Pain
  1. Friedman (2017) Ann Emerg 70(2): 169-76 +PMID: 28187918 [PubMed]
Systemic Corticosteroids (variable evidence)
1. Efficacy
  1. Variable benefit over NSAIDs and increased risk of adverse effects
  2. May reduce radicular pain in the short term
  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. Single Parenteral dose of Dexamethasone 10 mg IV/IM may offer short-term relief
    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)
