      2. Increased pinprick sensation
  6. Differential Diagnosis
    1. Femoral Neuropathy
    2. Lumbar radiculopathy (L2-3, L3-4)

    1. Electromyogram (EMG)
  8. Management
    1. Clothing changes
      1. Avoid wide belts
      2. Avoid tight garters or girdles
    2. Weight loss
    3. Capsaicin
    4. Elavil 30 mg qhs
    5. Local anesthetic and Corticosteroid
    6. Surgery rarely indicated
      1. Surgical Decompression
      2. Destruction of lateral femoral cutaneous nerve
  9. Course
    1. Spontaneous resolution in many cases by 2 years
