Which symptom is not typical of Complex Regional Pain Syndrome?

• A. Burning pain
• B. Shiny skin
• C. Abnormal sweating and hair growth
• D. Normal sweating

Answer: (D)

CRPS involves autonomic and trophic changes in the affected limb, so you see pain with burning quality, skin changes that can appear shiny from vasomotor instability, and altered autonomic functions like sweating and hair growth. Abnormal sweating and hair growth reflect this autonomic disruption. A normal sweating pattern, by contrast, would not align with the autonomic disturbances characteristic of CRPS. Therefore, normal sweating is not typical of the syndrome, while the other signs fit what CrPS commonly presents with.
