Complex Regional Pain Syndrome
Complex Regional Pain Syndrome
(CRPS; Reflex Sympathetic Dystrophy [RSD]; Causalgia; Sympathetically Maintained Pain)
- CRPS 1, also called reflex sympathetic dystrophy or RSD, has no observable nerve damage.
- CRPS 2, also called causalgia, produces similar symptoms after a verified nerve injury has occurred.

- Sensitivity to touch or even a light breeze
- Swelling in the arm or leg
- Unusual sweating patterns
- Excessively warm or cool skin
- Hair and nails changes which may become brittle and crack
- Abnormal movement in the arm or leg, such as a tremor, jerking, or spasms
- A pale, blue, and/or shiny look to the skin
- Limited joint movement
- An initial traumatic or painful event to a limb, or keeping the limb still for a period of time
- Continuing pain in the limb that is out of proportion to any stimulus, such as pain with even light touch
- Swelling, changes in skin blood flow, movement problems,or temperature changes only in the affected limb
- No other cause for the symptoms
- Pictures may need to be taken of your internal body structures. This can be done with:
- The electrical activity in your nerves and muscles may need to be tested. This can be done with:
- You may need to have your body's heat measured. This can be done with a thermogram.
- You may need to have your autonomic nervous system evaluated. This can be done with quantitative sudomotor axon reflex test (QSART).
- Pain relievers
- Antiseizure medications
- Topical pain relievers that are applied to the skin
- Nerve block injections
- Early use of pain relievers after trauma
- Use of sympathetic nerve block after trauma
- Desensitization techniques, if needed
- Use of vitamin C may reduce the risk of CRPS after a wrist fracture.
