What is piriformis syndrome?

As a recognised cause of gluteal and sciatic leg pain, piriformis syndrome can lead to significant discomfort and disruption to everyday activities like driving, working at a desk, or going for a walk. It is a condition that frequently mimics lumbar disc pathology, making accurate diagnosis critical to effective recovery. This fact sheet is designed to provide you with a clear understanding of piriformis syndrome, how it differs from lower back conditions, and how targeted physical therapy and chiropractic care can help restore movement.

In this article, Dr. Simon Nash (Chiropractor) discusses what piriformis syndrome is, its primary symptoms, and the comprehensive, conservative approaches used to treat it.

Understanding Piriformis Syndrome

Piriformis syndrome occurs when the piriformis muscle a small, flat muscle located deep within the gluteal region becomes irritated, tight, or inflamed, causing it to compress or irritate the sciatic nerve.

The piriformis muscle plays a vital role in lower body movement, assisting in lateral rotation of the hip and stabilising the hip joint during walking and running. Because the sciatic nerve passes underneath and in some individuals, directly through the piriformis muscle, any spasm or muscular hypertonicity can directly impinge upon the nerve.

“The piriformis muscle is a muscle that sits deep within the hip, and it actually runs over the top of the sciatic nerve,” Dr. Nash explains.

“So when you end up with irritation within that muscle, or tearing, or the muscle’s really tight, that could then potentially impinge onto the sciatic nerve and create pain down the leg.”

Key Symptoms and Causes

Piriformis syndrome typically manifests as local tenderness in the buttock, accompanied by radiating symptoms down the back of the thigh and leg.

“Piriformis syndrome can also be locally sore right across the back of the buttock, and be quite tender to sit down, very sore to move around,” says Dr. Nash.

When the sciatic nerve becomes compressed, patients frequently report:

1. An aching, burning, or shooting sensation starting in the gluteal area and extending down the back of the leg.
2. Tingling or numbness in the leg or foot.
3. Increased pain after prolonged sitting, standing, or walking.
4. Pain when rising from a chair or during hip rotation.

The underlying causes often range from acute overuse injuries (such as sudden repetitive strain from sports or heavy lifting) to prolonged sitting on hard surfaces, which causes direct compression and reduced blood flow to the muscle.

Differential Diagnosis: Disc Bulges vs. Piriformis Syndrome

One of the main challenges in managing piriformis syndrome is distinguishing it from other lumbar spine conditions, as both can cause nerve irritation down the leg.

“Piriformis syndrome is one of the biggest causes of sciatica,” states Dr. Nash. “A lot of people, when they come in with sciatic pain, would think it’s a disc bulge or something to do with their low back.”

While a lumbar disc herniation compresses the nerve root at the spine, piriformis syndrome represents an entrapment of the nerve further down its path in the gluteal space. A systematic review published in the European Spine Journal found that the features most consistently reported in piriformis syndrome were buttock pain, external tenderness over the greater sciatic notch, pain aggravated by sitting, and pain increased by movements that place the piriformis muscle under tension. The same review noted that distinguishing these patients from those with disc herniation or spinal stenosis remains an open research question (Hopayian et al., 2010).

“So piriformis syndrome can be quite debilitating, often confused with disc bulges and other irritations from the low back,” notes Dr. Nash. An updated systematic review by the same lead author reached a similar conclusion, describing piriformis syndrome as definable by a quartet of symptoms and signs while noting that the accuracy of the individual physical tests used to identify it has not yet been established (Hopayian & Danielyan, 2018). Accurate clinical evaluation therefore relies on a thorough history and a combination of assessments rather than any single test, in order to pinpoint the site of compression.

How Chiropractic Care Helps Piriformis Syndrome

Addressing piriformis syndrome requires a multi-faceted treatment plan aimed at releasing muscular tightness, alleviating nerve irritation, and improving hip joint mechanics.

“It is treated typically well using a range of different techniques such as active release technique, dry needling, manual adjustments and mobilisations around the hip and around the low back,” explains Dr. Nash.

Targeted Soft Tissue and Manual Therapy

Releasing the hypertonic muscle tissue is essential to relieve pressure on the sciatic nerve. Techniques such as active release, soft tissue therapy, and Dry Needling help target myofascial trigger points in the gluteal muscles. Additionally, targeted spinal and pelvic movements restored through Chiropractic Care ensure that joint dysfunction in the sacroiliac joint or lower spine isn’t contributing to secondary muscular compensation.

Recovery and Rehabilitation

In addition to clinic-based manual therapy, structured active rehabilitation plays a critical role in long-term relief and prevention.

“Giving the patient some exercises and rehabilitation to do at home… we usually see quite a good reduction and great results with piriformis syndrome treatments,” says Dr. Nash.

Home exercise protocols generally focus on:

1. Targeted Stretches: Gently lengthening the piriformis muscle to decrease pressure on the sciatic nerve.
2. Gluteal and Core Strengthening: Improving hip stability to reduce unnecessary strain on the deep rotators.
3. Ergonomic Adjustments: Modifying sitting habits and workstation setups to ensure prolonged pressure is minimised.

With consistency, many patients experience significant relief from acute symptoms within a few weeks, allowing a safe return to normal daily routines and active lifestyles.

Frequently Asked Questions (FAQs)

Q1: What is piriformis syndrome? A: Piriformis syndrome is a condition where the piriformis muscle in the buttock spasms, tightens, or swells, compressing the sciatic nerve and causing pain, numbness, or tingling down the leg.

Q2: How can I tell if my leg pain is from a disc bulge or piriformis syndrome? A: While both conditions cause radiating leg pain, a disc bulge usually originates with low back discomfort and nerve irritation at the spine, whereas piriformis syndrome often stems from deep gluteal tenderness and local pressure on the nerve near the hip. A practitioner performs physical tests to differentiate between the two.

Q3: Does sitting make piriformis syndrome worse? A: Yes. Prolonged sitting exerts direct pressure on the piriformis muscle, which can exacerbate muscle tightness and increase compression on the sciatic nerve.

Q4: What treatments are used for piriformis syndrome? A: Effective non-invasive care often includes a combination of soft tissue therapies (such as active release technique), dry needling, joint mobilisations, and targeted stretching and strengthening exercises.

Q5: Can stretching alone fix piriformis syndrome? A: While stretching the piriformis muscle helps relieve tension, long-term resolution often requires addressing underlying hip or pelvic mechanics, strength imbalances, and posture through a structured care plan.

Q6: How long does it take to recover from piriformis syndrome? A: Recovery times vary based on severity and individual compliance with rehab exercises. Many individuals notice improvements within a few weeks of beginning targeted conservative therapy.

Something that we often see in the clinic and we get a lot of questions about is piriformis syndrome. So piriformis syndrome is one of the biggest causes of sciatica. A lot of people, when they come in with sciatic pain, would think it’s a disc bulge or something to do with their low back. But the piriformis muscle is a muscle that sits deep within the hip and it actually runs over the top of the sciatic nerve. So when you end up with irritation within that muscle or tearing or the muscle’s really tight, that could then potentially impinge onto the sciatic nerve and create pain down the leg. Piriformis syndrome can also be locally sore right across the back of the buttock and be quite tender to sit down, very sore to move around.
