By Zach Mayfield, LMT — Founder of Body In Gear Physical Therapy in Palatine, IL. His practice is built around diagnosing the root cause of chronic and unexplained pain — often soft tissue dysfunction — before building a treatment plan.
Key distinction: Piriformis syndrome accounts for an estimated 5–6% of sciatica cases. It needs a fundamentally different treatment approach than disc-related sciatica — even though the symptoms can feel identical.
For sciatica caused by piriformis muscle tightness compressing the sciatic nerve, myofascial release can help — research on soft tissue techniques for piriformis syndrome shows benefit for pain and function, though study quality varies. Sciatica has multiple possible causes, and myofascial release only addresses the soft tissue ones, which is why an accurate diagnosis matters before treatment starts.
What Causes Sciatica?
Sciatica is pain, tingling, or numbness that radiates along the sciatic nerve, typically from the lower back through the buttock and down the leg. It's most often associated with a herniated disc pressing on a nerve root, but that's not the only cause. Piriformis syndrome — where the piriformis muscle, located deep in the buttock near the sciatic nerve, becomes tight or irritated and compresses the nerve — is responsible for an estimated 5–6% of sciatica cases. This distinction matters clinically: disc-related sciatica and piriformis-related sciatica need different treatment approaches, even though the symptoms can feel similar.
Does Myofascial Release Help Sciatica From Piriformis Syndrome?
When sciatica is coming from piriformis tightness rather than a disc issue, soft tissue treatment has a real place in the evidence base. A study published in the Journal of Population Therapeutics and Clinical Pharmacology examined myofascial release technique combined with conventional physical therapy for piriformis syndrome patients and found the combination effective at reducing pain and functional disability. Separately, research on physiotherapy approaches for piriformis syndrome has found that combining nerve mobilization techniques with piriformis release produces meaningful symptom improvement.
How Does Piriformis-Related Sciatica Feel Different From Disc-Related Sciatica?
- Worsens with prolonged sitting
- Aggravated by crossing legs
- Affects women ~6x more than men
- Deep buttock tenderness
- Worsens with forward bending
- Aggravated by coughing/sneezing
- Equal gender distribution
- Correlates with spinal positions
How Does Myofascial Release Target Piriformis-Related Sciatica?
A therapist applies sustained pressure to the piriformis and surrounding hip musculature to reduce tightness and take pressure off the sciatic nerve where it passes nearby. Because piriformis syndrome often involves referred pain and interconnected muscle groups, treatment frequently extends beyond the piriformis itself to the surrounding hip and lower back fascia. Body In Gear dedicates a full 50-minute session to this work — enough time to actually work through deep hip musculature.
What Should I Expect During Treatment?
Diagnosis comes first. Because piriformis-related sciatica and disc-related sciatica can present similarly, an accurate evaluation matters before any treatment plan is built. If soft tissue is identified as the driver, sessions typically combine medical massage to reduce guarding with targeted myofascial release of the piriformis and surrounding hip fascia. If a specific adhesion is located, Manual Adhesion Technique may be used to address it directly.
Can Myofascial Release Be Combined With Other Treatments for Sciatica?
Often, yes. Nerve mobilization techniques — gentle movements designed to help the sciatic nerve glide more freely within surrounding tissue — are sometimes used alongside soft tissue work for piriformis-related cases. Corrective exercise targeting hip strength and stability is also commonly paired with manual therapy, since addressing the muscular imbalances that contributed to piriformis tightness helps prevent recurrence.
What Should I Avoid If I Have Sciatica?
Prolonged sitting, especially with legs crossed, tends to aggravate piriformis-related sciatica specifically. Aggressive stretching or self-massage into an acutely irritated sciatic nerve can worsen symptoms rather than help. If pain is accompanied by significant weakness, loss of sensation, or bladder or bowel changes, that's outside what soft tissue therapy addresses and warrants prompt medical evaluation instead.
Where This Fits at Body In Gear
Sciatica gets treated differently depending on what's actually causing it — and piriformis-related cases respond to a fundamentally different approach than disc-related ones. Body In Gear's diagnostic-first intake identifies which situation you're in before recommending myofascial release, medical massage, or a referral for further evaluation.
