What is Piriformis Syndrome?
The piriformis is a small, flat muscle located deep in the buttock. It runs from the sacrum at the base of the spine to the upper part of the femur (thigh bone). Its primary role is to assist with hip movement, especially rotation and stabilisation during activities like walking, standing, and turning.
The sciatic nerve travels from the lower back down into the leg and passes very close to the piriformis muscle—and in some cases, even runs through it. If the piriformis becomes tight, irritated, or overworked, it can place pressure on the sciatic nerve, leading to symptoms similar to sciatica.
Common Symptoms
Symptoms of piriformis syndrome often develop gradually and may worsen over time. These can include:
- A deep ache or burning sensation in the buttock
- Pain that increases with sitting, driving, or climbing stairs
- Intermittent sharp or shooting pain down the back of the thigh
- Tingling, numbness, or “pins and needles” in the leg
- Tenderness when pressing into the buttock area
What Causes It?
Piriformis syndrome usually develops due to a mix of contributing factors rather than a single cause. It may appear after long periods of sitting, particularly on firm surfaces, or following a sudden increase in physical activity such as running or hiking.
Other common contributing factors include:
- Weakness in the gluteal (buttock) muscles, causing the piriformis to work harder than normal
- Reduced hip mobility or stiffness in the joint, increasing muscle tension
- Movement pattern changes that place extra load on the area
- Prolonged or uneven postures during daily activities or sleep positions
How Physiotherapy Can Help
A physiotherapist will assess your condition to confirm the diagnosis and identify contributing factors such as muscle imbalance, joint stiffness, or lifestyle habits.
Treatment typically focuses on addressing the underlying causes, not just the symptoms. This may include:
- Strengthening exercises for the gluteal muscles to reduce strain on the piriformis
- Techniques to improve sciatic nerve mobility if irritation is present
- Hands-on treatment and soft tissue techniques for short-term pain relief
- Guidance on modifying daily activities that may be aggravating the condition
- Advice on posture, movement habits, and ergonomic setup at work or home
Over time, the goal is to reduce pain, improve movement quality, and prevent recurrence by restoring balanced function in the hip and surrounding muscles.
