According to the Budapest criteria, which of the following is NOT considered a sympathetic symptom of CRPS?

The Budapest criteria for Complex Regional Pain Syndrome (CRPS) delineate a variety of symptoms that can be categorized as either sensory, vasomotor, sudomotor, or motor. Among these categories, sympathetic symptoms typically involve the autonomic nervous system's response and include features such as changes in skin temperature, swelling, and pain sensations like allodynia.

Numbness, while it can be experienced by patients with CRPS, is not classified under sympathetic symptoms in the context of the Budapest criteria. It is rather associated with sensory deficits. Therefore, the correct choice identifies numbness as the symptom that is not considered sympathetic, while the other symptoms — allodynia, swelling, and temperature change/sensitivity — are recognized as part of the sympathetic responses linked to CRPS. This reflects the complexity of the condition, where a mix of sensory, motor, and autonomic symptoms can manifest distinctly.
