Piriformis syndrome: 6 signs it may be causing your hip and leg pain

Hip or buttock pain that travels down your leg can make sitting, walking or exercising frustrating. One possible cause is piriformis syndrome, a condition involving irritation or compression of the sciatic nerve near the piriformis muscle. Because several back, hip and nerve problems can cause similar symptoms, it’s important not to assume piriformis syndrome is the answer based on pain alone.

A physical therapy evaluation can help identify what may be contributing to your symptoms and what type of care fits your needs.

What is piriformis syndrome?

The piriformis is a small muscle deep in the buttock. It helps control hip movement and sits close to the sciatic nerve. Piriformis syndrome may develop when this area irritates or compresses the sciatic nerve.

Symptoms can resemble sciatica because both may involve pain that travels from the buttock into the leg. However, sciatica describes symptoms related to the sciatic nerve and can have several causes. Piriformis syndrome is one possible source. Lumbar spine conditions and other hip or pelvic problems can cause similar symptoms, which is why a clinical evaluation matters.

6 symptoms that may be associated with piriformis syndrome

No single symptom can confirm piriformis syndrome. A clinician may look at your history, symptom pattern, movement and response to specific exam positions. The following signs can provide useful clues:

1. Deep pain in one buttock

A common symptom of the syndrome is a deep ache, burning feeling or sharp pain in the buttock. The discomfort may feel centered around the back of the hip rather than the front or side. Some people notice it after activity, while others feel it during daily tasks.

Buttock pain has been one of the most commonly reported features of piriformis syndrome. However, buttock pain can also come from other muscles, joints or nerves.

2. Pain that gets worse with prolonged sitting

Sitting for a long time may increase pressure around the buttock and make symptoms more noticeable. You may find yourself shifting positions often or standing to reduce discomfort.

Pain aggravated by sitting is another commonly reported feature of piriformis syndrome. If sitting also causes numbness, tingling or leg pain, a clinician can help determine whether a nerve may be involved.

3. Pain that travels down the back of the leg

Piriformis syndrome can produce sciatica-like symptoms. Pain may start in the buttock and travel into the back of the thigh or farther down the leg.

Radiating pain does not automatically mean the piriformis is responsible. A lumbar disc problem, spinal stenosis or another source of sciatic nerve irritation can create a similar pattern. The location of pain is one part of the evaluation, not a diagnosis by itself.

4. Tingling or numbness in the buttock or leg

Some people with piriformis syndrome report tingling or numbness along the path of the sciatic nerve. These sensations may occur with pain or appear separately.

Changes in sensation deserve attention, especially when they are new, persistent or worsening. A physical therapist or other health care provider can assess strength, sensation and movement to look for signs of nerve involvement.

5. Tenderness deep in the buttock

The area around the piriformis may feel tender when pressure is applied. A clinician may also check whether certain positions reproduce the familiar symptoms.

Tenderness alone is not enough to diagnose the condition. Other structures in the buttock and hip can also become sensitive. Your provider may compare several findings before deciding what is most likely contributing to your pain.

6. Symptoms that increase with certain hip movements

Movements that place tension on the piriformis can sometimes reproduce symptoms. You may notice discomfort with climbing stairs, squatting, running or changing hip position.

During an evaluation, a physical therapist may use specific movement tests to see whether your symptoms change when the hip is flexed or rotated. These tests are interpreted alongside your history and the rest of the exam.

Piriformis syndrome can be difficult to identify because its symptoms overlap with other causes of hip, buttock and leg pain. A clinician may consider your lower back, hip, pelvis, muscles and nerves rather than focusing on one structure.

That broader evaluation can help rule out other problems and guide a more appropriate plan. Imaging is not always the first step. Depending on your symptoms, a provider may use it or other testing mainly when another condition needs to be investigated.

FAQs about piriformis syndrome

Where is piriformis syndrome pain usually felt?

Piriformis syndrome commonly involves deep buttock pain. Some people also experience pain, tingling or numbness that travels into the back of the leg. These symptoms can overlap with other conditions, so location alone cannot confirm a diagnosis.

Does piriformis syndrome cause sciatica?

Piriformis syndrome may cause sciatica-like symptoms when the sciatic nerve is irritated near the piriformis muscle. However, sciatica can have several causes, including problems involving the lumbar spine.

Can sitting make piriformis syndrome symptoms worse?

It can for some people. Pain that increases during prolonged sitting is one commonly reported feature, but it is not specific enough to diagnose piriformis syndrome by itself.

How does a physical therapist evaluate piriformis syndrome?

A physical therapist may review your symptoms and activity history, then assess your movement, strength, sensation and hip positions. The goal is also to look for other possible causes of buttock or leg pain.

Can physical therapy help with piriformis syndrome?

Physical therapy may be part of conservative care. Treatment can include mobility exercises, strengthening, activity changes and education based on the person’s symptoms and exam findings.

Is piriformis syndrome the same as sciatica?

No. Sciatica describes symptoms involving irritation of the sciatic nerve. Piriformis syndrome is one possible cause of sciatic nerve irritation near the buttock.

What activities may irritate the piriformis area?

Some people notice symptoms during prolonged sitting, stair climbing, running, squatting or certain hip movements. Which activities matter most can vary from person to person.

Should I stretch my piriformis if my leg hurts?

Not automatically. Leg pain can come from several sources, and stretching the wrong area may not address the problem. An evaluation can help determine which exercises are appropriate for your symptoms.

Does piriformis syndrome show up on an MRI?

Piriformis syndrome is mainly diagnosed through clinical evaluation. Imaging may sometimes be used to investigate or rule out other conditions rather than confirm piriformis syndrome itself.

When should hip or leg pain be evaluated?

Consider an evaluation if symptoms persist, worsen or interfere with daily activity. Seek prompt medical attention for severe weakness, bowel or bladder changes or other major neurologic symptoms.
