This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Miscellaneous, Subject name: Orthopaedics
A 55-year-old woman is noted to have a traumatic injury to her right thigh. Which of the following is most sensitive for the diagnosis of compament syndrome 
Select and explain. 
A. Pulselessness, B. Paresthesias, C. Pain, D. Pallor
C: Pain
Answer: C: Pain 
Explanation: Pain, typically severe and even out of propoion to the injury, represents the first and most sensitive symptom of compament syndrome. Pain, however, is extremely nonspecific. Pulselessness represents a very late finding, and therefore the finding of a palpable pulse should not exclude compament syndrome in the differential diagnosis.
