Piriformis Syndrome and Chiropractic: When Your Sciatica Isn't Actually From Your Disc
You've had the MRI. The doctor looked at the results and said everything looks "normal" — no herniated disc, no significant stenosis, nothing that jumps out. And yet, the burning, aching, radiating pain running from your buttock down your leg is still very much there. You're not imagining it. You're not being dramatic. And you are absolutely not alone.
If this sounds familiar, there's a strong chance you've been living with piriformis syndrome — one of the most frequently missed and misdiagnosed causes of sciatica-like leg pain. It mimics a disc problem almost perfectly, which means many people spend months (sometimes years) being treated for the wrong thing. Piriformis syndrome chiropractic care takes a completely different approach — and for patients who haven't responded to standard disc treatments, it can be the answer they've been waiting for.

What Is Piriformis Syndrome?
The piriformis is a small but powerful muscle located deep in your buttock, running from your sacrum (the triangular bone at the base of your spine) to the top of your femur. Its job is to help rotate your hip outward. The sciatic nerve — the longest nerve in your body — runs either directly beneath or, in some people, straight through the piriformis muscle.
When the piriformis tightens, spasms, or becomes inflamed, it can compress or irritate the sciatic nerve right there in the buttock. The result? Pain, numbness, and tingling that shoot down the back of the leg — symptoms that feel virtually identical to sciatica caused by a disc problem.
Here's the critical difference: disc sciatica is caused by nerve compression *inside* the spinal canal — something an MRI can detect. Piriformis syndrome involves compression *outside* the spine, at the level of the muscle itself — something that won't show up on any MRI. This is precisely why it gets missed so often.

How Is Piriformis Syndrome Different From Disc Sciatica?
Because the symptoms overlap so heavily, the distinction comes down to careful clinical examination — not imaging. Here are some of the most telling differences:
Pain That Worsens With Sitting
Piriformis syndrome pain tends to spike when you sit for extended periods — particularly when seated on a hard surface or when driving. Sitting directly compresses the piriformis and aggravates the sciatic nerve. Disc-related sciatica can worsen with sitting too, but the pattern and location of discomfort often differ.
The FAIR Test
One of the most reliable clinical checks for piriformis syndrome is the FAIR test (Flexion, Adduction, Internal Rotation of the hip). When the hip is moved into this position, it stretches and compresses the piriformis — and if that's your source of pain, you'll typically feel it immediately. A positive FAIR test strongly suggests piriformis involvement, even when your MRI is clean.
Hip External Rotator Tightness
People with piriformis syndrome often present with noticeable tightness in the hip external rotators — a cluster of small, deep muscles that work alongside the piriformis. This tightness can affect how you walk and stand, and it's frequently tied to sacroiliac (SI) joint imbalance or pelvic misalignment. (If SI joint dysfunction sounds familiar, our post on SI joint pain and chiropractic is worth a read.)
No Neurological Red Flags on Disc Testing
Classic disc sciatica often shows weakness in specific muscle groups, reduced reflexes at the knee or ankle, or a positive straight-leg-raise test. Piriformis syndrome may produce radiating pain during certain tests, but the classic disc-positive findings are typically absent.

Why Standard Disc Treatments Don't Resolve Piriformis Syndrome
This is where things get frustrating for patients. If your provider has been treating you for a disc problem — with traction, flexion-distraction, anti-inflammatory medication, or even epidural injections aimed at the spinal canal — and you're still hurting, it's not because treatment failed. It's because the target was wrong.
Piriformis syndrome requires treatment aimed at the *muscle and surrounding soft tissue*, along with correction of the *pelvic and hip alignment issues* that caused the piriformis to tighten in the first place. You can't stretch or decompress your way out of a muscle problem by treating a disc that isn't involved. This is also why lumbar radiculopathy caused by true disc involvement requires a different clinical pathway than piriformis syndrome — even when the leg symptoms look the same.

Dr. Propper's Chiropractic Approach to Piriformis Syndrome
At Propper Chiropractic, established 1989 and serving Westport and Fairfield County families for over three decades, Dr. Adam Propper takes a layered approach to piriformis syndrome — because in most cases, there's more than one structure contributing to your pain.
Pelvic and Hip Alignment Correction
Piriformis tightness rarely exists in a vacuum. It's almost always driven by an underlying imbalance in the sacroiliac joint, pelvis, or lumbar spine. When your pelvis is tilted or rotated — even subtly — the piriformis compensates and chronically contracts to stabilize your hip. Dr. Propper uses gentle spinal and pelvic corrections to restore proper alignment, reducing the mechanical load on the piriformis so it can finally let go.
Soft Tissue Release for the Piriformis and Hip Rotators
Beyond alignment, the muscle itself needs direct attention. Dr. Propper incorporates targeted soft tissue release techniques to address the piriformis and the surrounding deep hip rotators, reducing spasm, improving flexibility, and taking pressure off the sciatic nerve.
Cox Technique for the Lumbar Spine Component
Many patients don't have *purely* piriformis syndrome — they have both piriformis dysfunction *and* some degree of disc irritation in the lumbar spine. As a Certified Cox Technique Specialist, Dr. Propper can address the lumbar disc component with gentle, research-backed flexion-distraction care while simultaneously treating the piriformis. This combined approach is one of the key reasons patients who've been stuck elsewhere begin to make meaningful progress here.
Nutritional Anti-Inflammatory Support
Chronic muscle spasm and nerve irritation are significantly worsened by systemic inflammation. Through Nutrition Response Testing, Dr. Propper may identify specific nutritional imbalances that are keeping your body in a chronic inflammatory state — and recommend targeted, whole-food-based support (including Standard Process protocols) to help your tissues heal from the inside out.

When to Seek Emergency Care
While piriformis syndrome is painful and disruptive, it is not a medical emergency. However, certain symptoms should prompt you to seek immediate care at an emergency room rather than a chiropractic office:
- Progressive weakness in the leg or foot (foot drop)
- Loss of bowel or bladder control
- Saddle area numbness (inner thighs, groin, or genitals)
These can indicate serious spinal cord or cauda equina involvement that requires urgent medical evaluation.

You Deserve a Real Answer — Not Just More of the Same
If you've been told your MRI is normal while you're still living with real, limiting leg pain, piriformis syndrome may be the missing diagnosis. With 67+ five-star reviews and a reputation built on genuinely listening to patients, Dr. Propper has helped many Fairfield County families finally find relief after months of frustration elsewhere.
Propper Chiropractic offers comprehensive chiropractic care with flexible scheduling — including Saturday morning appointments from 8–10am, when most other Westport-area chiropractors are closed.
