This injury may be acute or progressive; acute injuries are often associated with trauma, such as a car accident or sports injury which places sudden pressure on the ligament. Progressive injuries usually result from the continuous completion of actions or movements that place strain on the ligament; examples of these actions include bending down and twisting.

Symptoms of iliolumbar ligament sprain
