Pain out of proportion to the injury is the hallmark sign of compartment syndrome. This severe, unrelenting pain is often described as excruciating and is not relieved by normal pain management measures. While swelling and decreased pulses can occur in other injuries, the intense pain characteristic of compartment syndrome is a crucial distinguishing factor. It's important to note that loss of pulse is a late sign and should not be relied upon for early diagnosis. The other options, while they may be present in compartment syndrome, are not specific to this condition and can be seen in various other musculoskeletal injuries.
