What Is Piriformis Syndrome?
A piriformis syndrome is a condition in which the piriformis muscle irritates or compresses the sciatic nerve near the buttock. The condition may cause deep buttock pain, tingling, numbness, or pain that travels into the back of the thigh. Symptoms can resemble lumbar nerve irritation, so the surrounding hip and spine require careful assessment.

Key Takeaways About Piriformis Syndrome
- Piriformis syndrome involves the piriformis muscle near the sciatic nerve.
- Symptoms may change with sitting, walking, or hip movement.
- Buttock pain does not always come from the lumbar spine.
How Piriformis Syndrome Works

Piriformis Syndrome involves the relationship between the piriformis muscle and the sciatic nerve. The muscle sits deep in the buttock and helps move and stabilize the hip. Irritation, tightness, or local swelling may affect the nearby nerve and create symptoms in the buttock or leg.

Clinicians assess the symptom pattern along with hip motion, muscle tenderness, strength, sensation, and lumbar spine findings. Sciatic nerve symptoms from the lower back can feel similar, so the source cannot be identified from pain location alone. A physical examination helps compare the hip, pelvis, and lower back before care is selected.

From the Arrowhead Clinic Chiropractor Atlanta team
When we assess piriformis syndrome, we review the hip, pelvis, and lumbar spine together. Our team looks at movement, tenderness, strength, and symptom changes to distinguish local buttock irritation from nerve symptoms that begin in the lower back.
Piriformis Syndrome in Practice: A Real-World Example
A person may develop deep buttock discomfort after prolonged sitting and notice symptoms extending into the back of the thigh. During Sciatica Treatment, the examination considers the piriformis muscle alongside the lumbar spine and pelvic region.
