What symptom is characteristic of dislocation?

Severe pain is a hallmark symptom of dislocation. This intense pain occurs due to the trauma inflicted on the surrounding ligaments, joint capsule, and nerves when the bones are displaced from their normal alignment. The disruption of these tissues leads not only to pain but often to an immediate inability to use the affected joint effectively, distinguishing dislocation from other injuries.

While some dislocations may exhibit signs such as swelling or skin discoloration as secondary symptoms, the primary and most notable symptom is the severe pain that typically accompanies the initial injury. Other options such as minor swelling are not definitive indicators, and increased range of motion is contrary to the nature of a dislocated joint, which would restrict movement due to the pain and mechanical instability.
