Neuropathic pain

Background

• Neuropathic pain responds best to multifaceted approach - not to opiates
• If opiates can be avoided, it helps PCPs and pain management specialists create a better regimen
• Cornerstone of pain management is activity (exercise, PT, aquatherapy), but opiates/benzodiazepines restrict this

Management

• Do not consider starting patients on medications unless they will definitely obtain good follow-up
• First line medication options (all have NNT from ~2-3 or better)
  • AEDs - gabapentin, topiramate
  • TCAs - amitryptyline, nortriptyline
  • Duloxetine (especially if TCAs contraindicated)
  • Pregabalin
  • NSAIDs and tylenol
• Second line medications (temporary relief, not long term)
  • Tramadol
  • Muscle relaxants - cyclobenzaprine, methocarbamol, diazepam
• Refer to pain specialist for multidisciplinary approach
• Pain specialists can offer (discussion with patient in ED):
  • Injections - trigger point, epidural steroid injections, facet injections, medial branch blocks, joint steroid injections
  • Radiofrequency ablations
  • Spinal implants
  • Determination of long-term opiates
  • Pain psychology
  • Spinal manipulation
• Lifestyle changes
  • Weight loss
  • Sobriety, reduction of polypharmacy, smoking cessation
  • Exercise, avoidance of bed rest, core strengthening
