Which symptom is unlikely to be present in a person with Complex Regional Pain Syndrome?

In the context of Complex Regional Pain Syndrome (CRPS), the symptom that is least likely to be present is unilateral facial paralysis. CRPS is characterized by severe pain, often accompanied by a history of trauma or surgery in the affected area. Patients typically experience intense pain sensations that may be described as burning, along with noticeable changes in skin color and temperature in the affected limb.

Facial paralysis, on the other hand, is not associated with CRPS. It commonly indicates other neurological or muscular disorders rather than the symptoms specific to CRPS. In summary, while CRPS can present with a variety of symptoms related to pain, sensory and autonomic changes in the extremities, facial paralysis does not fit within the expected clinical picture of this syndrome.
