Pain in CRPS 1 has the following characteristics:

  • Usually constant and disproportionate to the precipitant injury
  • May be exacerbated by ambient factors such as loud noises and emotional factors (eg, stress, light touch, active motion, passive motion)
  • May be described as burning, cutting, searing, pressure, or tearing
  • Usually begins locally but may progress to involve the entire extremity
