Which of the following is a vasomotor disturbance seen in CRPS?

Explanation:
Vasomotor disturbances in CRPS come from autonomic nerves failing to properly regulate blood vessel tone, which changes skin blood flow and temperature. Temperature change is the classic sign because it directly reflects this autonomic control of vasodilation and vasoconstriction, leading to warmth or coolness in the affected limb that can differ from the other side and even fluctuate over time. Pain, edema, and joint stiffness can occur with CRPS as well, but they reflect sensory, inflammatory, and motor aspects rather than the autonomic regulation of vessel tone.
