Symptoms may include:
- burning, stabbing, grinding, throbbing pain
- movement or touch of the limb is intolerable
- muscle spasms
- local swelling
- sensitivity to touch, water, vibrations
- increased sweating
- changes in skin temperature
- changes in skin color

Sometimes there are no known causes for CRPS, although injury and surgery can be factors.
