What Is Piriformis Syndrome?
Piriformis syndrome is a condition in which the sciatic nerve becomes irritated or compressed in the buttock region near the piriformis muscle.
The piriformis is a small muscle located deep in the buttock. It helps control movement of the hip and assists with stability during walking and other lower-limb activities.
The sciatic nerve travels from the lower back and pelvis down the back of the leg. In most people, it passes underneath the piriformis muscle. However, anatomical variations can occur.
If the piriformis muscle becomes irritated, tight or enlarged, it may place pressure on the nearby sciatic nerve. This can produce symptoms that resemble sciatica.
What Are the Symptoms of Piriformis Syndrome?
People with piriformis syndrome commonly describe a deep ache in the buttock or gluteal region.
Symptoms may also include:
- Buttock pain
- Tingling or pins and needles
- Pain travelling into the hamstring
- Pain extending further down the leg
- Discomfort during prolonged sitting
- Pain when moving or rotating the hip
- Tenderness when pressure is applied to the buttock
- Symptoms during activities that load the hip muscles
In some cases, symptoms can extend as far as the foot.
Because these symptoms can resemble other forms of sciatic nerve pain, an accurate assessment is important.
What Causes Piriformis Syndrome?
Piriformis syndrome can develop for several reasons.
Possible contributing factors include:
- Trauma to the hip or buttock
- Repetitive overuse of the piriformis muscle
- Prolonged sitting
- Hip muscle weakness or imbalance
- Changes in hip biomechanics
- Increased piriformis muscle size or hypertrophy
- Repetitive sporting activities
- Anatomical variations involving the piriformis muscle or sciatic nerve
People who spend long periods sitting, including office workers, drivers and cyclists, may place prolonged pressure through the buttock region.
Athletes who repeatedly load the hip muscles may also develop irritation around the piriformis.
Can Sitting Cause Piriformis Syndrome?
Prolonged sitting can aggravate piriformis syndrome in some people.
Sitting places pressure through the buttock and can keep the hip in a relatively fixed position for extended periods.
For people who already have irritation around the piriformis muscle or sciatic nerve, long periods of sitting may increase symptoms.
Regular movement breaks, changes in sitting position and appropriate hip exercises may form part of a management plan.
Is Piriformis Syndrome the Same as Sciatica?
Piriformis syndrome and sciatica can produce similar symptoms, but they are not necessarily the same condition.
Sciatica describes symptoms associated with irritation or compression of the sciatic nerve. The source of that irritation can occur at different locations.
Common causes of sciatic-type symptoms may include:
- Lumbar disc irritation or disc herniation
- Lumbar spinal stenosis
- Nerve root irritation in the lower back
- Hamstring injuries
- Pelvic or sacroiliac conditions
- Piriformis syndrome
- Other less common neurological or structural conditions
For this reason, piriformis syndrome is often considered a diagnosis of exclusion.
Before diagnosing piriformis syndrome, a practitioner will usually assess whether symptoms could be coming from the lumbar spine, pelvis, hip or another structure.
How Is Piriformis Syndrome Diagnosed?
There is no single test that confirms every case of piriformis syndrome.
Assessment generally begins with a detailed history of your symptoms.
Your practitioner may then assess:
- Lumbar spine movement
- Hip mobility
- Muscle strength
- Neurological function
- Areas of tenderness
- Positions that reproduce symptoms
- Lower-limb movement patterns
The aim is to identify the most likely source of your symptoms while ruling out other conditions that may cause similar pain.
How Is Piriformis Syndrome Treated?
Treatment for piriformis syndrome varies depending on the individual.
The goal is usually to reduce irritation, improve hip function and address factors that may be contributing to excessive stress around the piriformis muscle.
Management may include:
- Soft tissue therapy
- Joint mobilisation or manual therapy
- Stretching exercises
- Hip strengthening exercises
- Movement and rehabilitation exercises
- Dry needling, where appropriate
- Taping
- Advice about sitting and activity modification
Treatment should be based on the findings of your assessment rather than relying on one specific technique.
Exercises for Piriformis Syndrome
Exercise can play an important role in managing piriformis syndrome.
However, repeatedly stretching the piriformis is not always the best solution.
Depending on the underlying cause, rehabilitation may focus on:
- Improving hip strength
- Strengthening the gluteal muscles
- Improving pelvic control
- Increasing hip mobility
- Gradually increasing tolerance to sitting or exercise
- Correcting movement patterns that may overload the buttock muscles
An individual exercise program can help address the factors contributing to your symptoms.
Chiropractic Care for Piriformis Syndrome
At the Institute of Sports and Spines in Tingalpa, our chiropractors assess the lower back, pelvis, hip and surrounding muscles when investigating sciatic-type pain.
If piriformis syndrome is suspected, treatment may involve a combination of hands-on therapy and rehabilitation.
The aim is to improve movement, reduce aggravating factors and help you gradually return to normal activities.
Because buttock pain and leg symptoms can have several different causes, an accurate diagnosis is an important first step.
When Should You Seek Help?
Consider seeking an assessment if you experience:
- Persistent buttock pain
- Pain travelling down the back of the leg
- Tingling or pins and needles
- Symptoms aggravated by prolonged sitting
- Pain that is interfering with exercise, work or daily activities
- Ongoing symptoms that are not improving
Seek urgent medical attention if symptoms are associated with significant leg weakness, loss of bladder or bowel control, numbness around the groin or saddle region, severe unexplained pain, fever, or other concerning symptoms.
