Immediate care for a bone, muscle, or joint injury is crucial when there is numbness or coldness below the injury. This symptom can signify compromised blood flow or nerve function, which may indicate a serious condition such as a fracture, dislocation, or significant soft tissue damage. If blood circulation or nerve signals are affected, there is a risk of further injury or complications, making it essential to seek medical assistance promptly.

The other options, while they might indicate injury, do not reflect the same level of urgency. Minor swelling can occur with many injuries and is not necessarily a sign of something severe. Bruising that resolves quickly generally suggests a less significant injury and may not require immediate treatment. Similarly, the ability to move the injured part does not automatically indicate that no serious injury exists, as some injuries may still allow for movement without suggesting safety. However, numbness or coldness indicates potential damage that needs urgent medical evaluation.
