Piriformis Syndrome vs. Sciatica: Key Differences in Symptoms and Diagnosis

Both conditions cause buttock, hip, and leg pain, but they have distinct features. A healthcare professional should make the final diagnosis.

Pain Location

• Piriformis syndrome: Deep, aching pain in the buttock, sometimes radiating down the back of the thigh.
• Sciatica: Pain originates in the lower back and radiates through the buttock, thigh, calf, and foot.

Diagnostic Tests

Piriformis Test

• Piriformis syndrome: Pain when the hip is flexed, knee bent, and hip rotated inward while lying on the back.
• Sciatica: Not typically positive on this maneuver.

Straight Leg Raise Test

• Piriformis syndrome: Pain may occur, especially with inward hip rotation.
• Sciatica: Pain radiating down the leg during the test suggests sciatica.

Sciatic Nerve Stretch Test

• Sciatica: Pain when the extended leg is gently pulled toward the chest while lying supine.

Additional Symptoms

• Piriformis syndrome: Numbness/tingling in buttock or leg; difficulty sitting or walking for long periods.
• Sciatica: Leg weakness, muscle spasms, and in severe cases, bowel or bladder dysfunction.

Important: Only a qualified clinician can accurately differentiate these conditions through physical examination and imaging if needed.
