Which of the following is a common symptom of piriformis syndrome?

Piriformis syndrome occurs when the piriformis muscle, located in the buttocks, irritates the sciatic nerve due to inflammation or spasm. A common symptom experienced by individuals with piriformis syndrome is hip pain. This pain often manifests in the buttock area and can radiate down the leg, mimicking sciatic nerve pain. The relationship between the piriformis muscle and the sciatic nerve is crucial for understanding this syndrome, as irritation in the pelvic region can lead to discomfort in the hip area.

Shoulder pain, knee pain, and lower back pain can be caused by a variety of factors and conditions, but they are not directly associated with piriformis syndrome itself. The hallmark of this condition is specifically related to hip and buttock pain, which is why hip pain is the correct answer. Understanding the anatomical location and function of the piriformis muscle helps make it clear why hip pain is a primary symptom of this syndrome.
