Piriformis Syndrome vs Sciatica: How to Tell the Difference
One of the most common diagnostic confusions in physiotherapy is mistaking piriformis syndrome for true disc-related sciatica — or vice versa. Both conditions cause pain, numbness, and tingling radiating from the buttock down the leg.
But they have different causes, different examination findings, and crucially, different treatments. Getting the diagnosis right is the difference between effective targeted physiotherapy and weeks of misdirected treatment.
At Realign Rehab Clinic , NIT-5, Faridabad, our expert physiotherapists provide personalised, evidence-based care. We serve patients from NIT, Green Field Colony, Ballabhgarh, Sector 21–82, and across Faridabad.

Research Insight: Research published in the European Spine Journal found that up to 17% of patients diagnosed with discogenic sciatica actually have piriformis syndrome as the primary pain generator — confirming that accurate clinical diagnosis is critical and that physiotherapy assessment should precede imaging in most cases.
Causes and Risk Factors
- True sciatica (lumbar disc herniation or stenosis): compression of the sciatic nerve root at L4–S1
- Piriformis syndrome: compression or irritation of the sciatic nerve by the piriformis muscle in the deep buttock
- Sacroiliac joint dysfunction mimicking both conditions
- Hamstring origin tendinopathy at the ischial tuberosity (proximal hamstring)
- Referred pain from lumbar facet joints or trigger points
Signs and Symptoms
- True sciatica: leg pain following a dermatomal pattern (specific strip down the leg); worsened by bending forward; often associated with back pain; positive straight leg raise test
- Piriformis syndrome: deep buttock pain often described as 'sitting on a golf ball'; worsened by sitting for over 30 minutes; triggered by hip rotation movements; no true dermatomal pattern
- Both may cause numbness and tingling down the leg
- Both may cause difficulty sitting for prolonged periods
The key question I always ask is: where does the pain start? Disc sciatica typically starts in the lower back and shoots down the leg.
Piriformis syndrome starts deep in the buttock, often without any back pain at all. And the critical test is hip internal rotation with the knee bent — if that reproduces the exact pain, it is piriformis until proven otherwise.
- ✦ Up to 17% of patients diagnosed with disc sciatica actually have piriformis syndrome
- ✦ Piriformis syndrome is more common in women due to hip anatomy (wider Q-angle)
- ✦ True disc sciatica has a 90% resolution rate within 6–12 weeks with physiotherapy
- ✦ Misdiagnosis of piriformis as disc sciatica leads to unnecessary MRI and injection procedures
Physiotherapy Treatment at Realign Rehab, Faridabad
- Accurate differential diagnosis — the key to effective treatment
- For true sciatica: neural mobilisation (nerve flossing), disc-specific exercises, lumbar joint mobilisation, and core stability
- For piriformis syndrome: piriformis stretch, deep buttock soft tissue release, and dry needling
- Hip external rotator strengthening for both conditions (prevents recurrence)
- Postural correction and ergonomic assessment for desk workers
- Sacroiliac joint assessment and stabilisation where relevant
- TENS and electrotherapy for acute pain modulation
- Activity modification and progressive return-to-normal programme
Recovery Programme
Phase 1 — Pain Relief (Weeks 1–3): Manual therapy, electrotherapy (TENS/ultrasound), and gentle movement exercises to reduce inflammation and restore baseline function.
Phase 2 — Strengthening (Weeks 3–8): Progressive resistance training, neuromuscular re-education, and functional movement retraining.
Phase 3 — Return to Activity (Weeks 8–16): Sport- or work-specific conditioning, proprioception training, and a personalised home programme to prevent recurrence.

Frequently Asked Questions
How do I know if I have piriformis syndrome or disc sciatica?
Piriformis syndrome typically causes deep buttock pain worsened by sitting, without considerable back pain. Disc sciatica usually involves lower back pain with leg radiation in a dermatomal pattern.
A physiotherapy assessment will distinguish between the two — imaging is not usually necessary.
Does piriformis syndrome show on MRI?
Standard MRI rarely shows piriformis syndrome — it is primarily a clinical diagnosis based on physical examination. Specialised MRI sequences can sometimes show piriformis muscle enlargement or sciatic nerve compression.
What is the best treatment for piriformis syndrome?
Piriformis stretching, deep buttock soft tissue release, dry needling, and hip strengthening are the most effective treatments. Most cases resolve in 6–10 weeks with targeted physiotherapy.
Can disc sciatica resolve without surgery?
Yes — over 90% of lumbar disc herniations causing sciatica resolve with physiotherapy within 6–12 weeks. The disc material reabsorbs naturally.
Surgery is only needed for the small minority with severe, progressive neurological deficit.
What should I avoid with piriformis syndrome?
Prolonged sitting, hill running, and exercises requiring hip external rotation under load (like deep squats) aggravate piriformis syndrome. Your physiotherapist will guide you on activity modification.
