From the Dutch guidelines Patient version

What is Complex Regional Pain Syndrome type 1?
CRPS-I is a condition that can cause serious problems for patients and practitioners. It
normally occurs following an injury to an arm or leg, and can involve a combination of
symptoms:
- circulation disorders
- signs of inflammation
- signs of oxygen deficit
- structural abnormalities in tissues
- sweating disorders
- nerve disorders
Patients report the following problems: pain, temperature difference, impaired movement,
colour changes, hypersensitivity ('contact pain'), tremor, involuntary movements, muscle
spasms, paralysis, atrophy, swelling and changes in hair and nail growth.
A distinction is drawn between 'warm CRPS-I' and cold CRPS-I. Warm CRPS-I affects
95% of patients. In this form the skin is red and feels hot. Only 5% of patients experience
'cold CRPS-I' from the onset of the condition: the arm/leg feels cold, the skin is blue in
colour and circulation is impaired.
