Discomfort from too much sitting? Inactive glutes? Pain in the buttock or down the back of the leg? Even though it’s small, the piriformis muscle plays an important role in how the body moves. When this muscle becomes tight or irritated, it can lead to a condition known as piriformis syndrome.
In this guide, you’ll learn what the piriformis muscle does, what piriformis syndrome is, and which stretches and exercises may help relieve discomfort.
What Is the Piriformis Muscle?
The piriformis is a small muscle located deep in the buttock. It:
- Starts on the front surface of the sacrum (base of the spine)
- Passes through the greater sciatic foramen
- Attaches to the greater trochanter of the femur (upper thigh bone)
Its main functions include:
- External rotation of the hip
- Hip abduction
- Hip extension
Although small, the piriformis helps stabilize the hip during movement.
What Is Piriformis Syndrome?
Piriformis syndrome occurs when the piriformis muscle becomes tight, inflamed, or spasms, placing pressure on the sciatic nerve.
Because the sciatic nerve runs underneath—or sometimes through—the piriformis muscle, irritation of this muscle can compress the nerve.
This compression can cause symptoms similar to sciatica, including pain that travels from the buttock down the back of the leg.
Signs and Symptoms of Piriformis Syndrome
Common symptoms include:
- Pain in the buttock
- Pain down the back of the thigh
- Pain when sitting
- Pain when climbing stairs or walking uphill
- Reduced range of motion in the hip
- Tenderness in the piriformis area
Because these symptoms resemble other spinal or nerve conditions, diagnosis can sometimes be difficult.
Why Piriformis Problems Develop
The exact cause of piriformis syndrome is not always clear. However, several factors may contribute:
- Tight hip flexors
- Weak or inactive glute muscles
- Overuse of the hip rotator muscles
- Prolonged sitting
- Poor movement patterns
When the glute muscles become weak or inhibited, the piriformis may become overworked, leading to tightness or spasms.
Piriformis Syndrome Treatment Approach
If you experience persistent pain in the hip, buttock, or lower back, it’s important to consult a medical professional first.
Once cleared for exercise, a common corrective approach includes:
- Releasing tight muscles (such as hip flexors)
- Improving flexibility
- Strengthening the glutes
- Restoring normal movement patterns
