What are common signs indicating that a back injury may require medical attention?

The signs indicating that a back injury may require medical attention typically include severe pain, numbness, weakness, leg pain, swelling, and redness. This combination of symptoms suggests that there may be a more serious underlying issue, such as a herniated disc, spinal cord injury, or nerve impingement. Severe pain may indicate significant injury or damage, and numbness or weakness in the legs can suggest nerve involvement. Additionally, swelling and redness could point to inflammation or injury requiring professional assessment.

The other symptoms in the other choices, such as minor discomfort, occasional stiffness, or mild soreness, often do not necessitate immediate medical attention and may resolve with conservative management. Persistent headaches and fatigue could relate to a variety of health issues but are generally not directly indicative of a back injury needing urgent care. Therefore, the presence of the severe signs outlined signifies a potential serious condition that warrants professional evaluation.
