SI Joint Pain Chiropractor in Tulsa: Why It Feels Like Sciatica But Is Not
You have a deep ache at the top of your buttock that comes and goes. It gets worse when you stand from sitting, roll over in bed, or drive. Everyone keeps calling it sciatica. But what if it is not your nerve at all? What if it is your SI joint?
Quick answer
An SI joint pain chiropractor in Tulsa identifies and treats sacroiliac joint dysfunction, which is an under-recognized source of low back and buttock pain. A 2021 review in the European Spine Journal confirmed that SI joint dysfunction is frequently missed because it mimics sciatica and lumbar disc problems (Gartenberg et al., 2021). The sacroiliac joint connects your spine to your pelvis. When it moves too much (hypermobility) or too little (hypomobility), it produces a deep, one-sided ache that can refer into the groin, hip, or down the thigh. At Vanguard Chiropractic in Brookside, walk-ins are $40, no appointment needed. Call 918-948-7990.
TL;DR
- SI joint dysfunction is an under-recognized cause of low back pain that mimics sciatica but has a completely different mechanism.
- Sciatica = nerve root compression at the spine. SI joint pain = joint dysfunction at the pelvis. Different problem, different treatment.
- Common in postpartum women, runners, people who sit with crossed legs, and anyone with asymmetric loading patterns.
- A 2024 systematic review found manual therapy is effective for reducing disability in SI joint pain (Trager et al., 2024).
- Vanguard Chiropractic is walk-in, $40, no appointment, open evenings until 7pm and Saturdays.
What is the sacroiliac joint and why does it hurt?
The sacroiliac (SI) joint is where the base of your spine (the sacrum) connects to the large pelvic bone (the ilium) on each side. You have two SI joints, one on the left and one on the right.
Unlike the lumbar spine, the SI joint was not built for big movements. It moves a few millimeters. Its job is to transfer load from your upper body through the pelvis into the legs. It is a stability joint wrapped in some of the strongest ligaments in the body.
SI joint dysfunction happens when the joint either locks up (hypomobility) or loosens beyond normal (hypermobility). Both create pain. The mechanism is different for each.
Hypomobility (locked SI joint)
The joint gets stuck. The ligaments around it tighten. The muscles that cross the joint (gluteus maximus, piriformis, multifidus) go into protective spasm. You feel a deep, dull ache on one side of your low back, right at the top of the buttock. The pain often gets worse with transitions: sitting to standing, rolling over in bed, bending forward.
This is the pattern I see most often in people who sit with their legs crossed, sleep on one side every night, or have a repetitive one-sided loading pattern (like always stepping off the same foot). The asymmetric load slowly locks one SI joint while the other stays mobile.
Hypermobility (loose SI joint)
The joint moves too much. The ligaments have stretched. The surrounding muscles have to work overtime to stabilize a joint that should be self-stabilizing. This creates a different kind of pain: a sense of instability, a feeling that your pelvis is “out of place,” pain that shifts around and is hard to pinpoint.
This pattern is most common in postpartum women. During pregnancy, the hormone relaxin loosens the pelvic ligaments to allow childbirth. After delivery, those ligaments do not always tighten back fully. The SI joint stays loose, and the new mom is left with persistent pelvic and low back pain that nobody can quite explain.
It also shows up in runners and athletes who train on one leg more than the other, or who have a significant leg length difference.
SI joint pain vs sciatica: how to tell the difference
This is the most common mix-up I see. A patient comes in saying “I have sciatica” because their buttock hurts and sometimes the pain runs down the back of the thigh. They have been stretching the piriformis and taking ibuprofen. Nothing is working.
Here is how the two conditions differ:
| Feature | Sciatica | SI Joint Pain |
|---|---|---|
| Cause | Nerve root compression at L4, L5, or S1 | Joint dysfunction at the sacroiliac joint |
| Pain location | Buttock, back of thigh, often below the knee to the foot | Top of buttock, may refer to groin, hip, or back of thigh (rarely below the knee) |
| Pain character | Sharp, shooting, burning, electric | Deep, dull, aching |
| Worse with | Sitting, bending forward, coughing | Transitions (sit to stand), one-leg standing, stairs |
| Numbness/tingling | Common (specific dermatome pattern) | Uncommon |
| Provocation test | Straight leg raise reproduces leg pain | SI provocation cluster (FABER, Gaenslen, thigh thrust, compression, distraction) |
The clinical distinction matters because the treatment is different. Sciatica treatment focuses on the lumbar spine and the nerve root. SI joint treatment focuses on the pelvis and the joint itself. If you have been treating “sciatica” for months with no improvement, there is a real chance your SI joint is the actual problem.
SI joint dysfunction is one of the most commonly missed diagnoses in low back pain. If your treatment is not working, the diagnosis might be wrong.
Who gets SI joint pain?
SI joint dysfunction is not random. Certain groups are at much higher risk.
- Postpartum women. Relaxin loosens pelvic ligaments during pregnancy. After delivery, the SI joint may stay hypermobile for months or even years. Postpartum chiropractic care specifically addresses this pattern.
- Runners. The repetitive single-leg impact of running loads the SI joint asymmetrically. Weak glutes and poor pelvic control make it worse. Runners in Tulsa frequently present with SI dysfunction disguised as “hip pain.”
- People who sit with crossed legs. Crossing one leg over the other for hours twists the pelvis. One SI joint compresses while the other gaps. Do that daily for years and the asymmetry becomes structural.
- People with a leg length difference. Even a small difference (5mm or more) creates an asymmetric pelvic load. One SI joint works harder than the other. Over time, it complains.
- People with lumbar fusion. When the lumbar spine is surgically fused, the segments above and below the fusion take extra stress. The SI joint, which sits directly below L5, often picks up the load.
How I diagnose SI joint pain at Vanguard Chiropractic
There is no single test that confirms SI joint dysfunction. The gold standard in research is an image-guided anesthetic injection into the joint. But in clinical practice, a cluster of provocation tests is the standard approach.
I use a cluster of five tests:
- FABER test (Patrick’s test). You lie on your back. I put one ankle on the opposite knee and press the knee toward the table. Pain in the SI region is positive.
- Gaenslen’s test. One leg hangs off the edge of the table while I flex the other hip. This stresses the SI joint through counternutation and nutation simultaneously.
- Thigh thrust. Your hip is flexed to 90 degrees and I apply a downward force through the femur into the SI joint. Pain at the SI is positive.
- Sacral compression. You lie on your side. I press down on the ilium, compressing the SI joint. Pain at the joint is positive.
- Sacral distraction. You lie on your back. I press outward on both iliac crests, gapping the SI joints. Pain at the joint is positive.
If three or more of these five tests reproduce your pain, the SI joint is highly likely the source. I also check lumbar range of motion, straight leg raise, and dermatomal sensation to rule out nerve root involvement. If both the SI cluster and the nerve tests are positive, we may be dealing with two problems at once.
What the research says about SI joint treatment
Journal of Manual and Manipulative Therapy, 2024 (Trager et al.): Systematic review and meta-analysis of 16 randomized controlled trials involving 421 adults. Found that SI joint manual therapy has a statistically significant moderate effect in reducing disability. Pain results were less conclusive but trended toward improvement.
What this means in plain terms: Manual therapy helps SI joint patients move better and function better. The disability improvement is significant. That is the metric that matters most for daily life.

European Spine Journal, 2021 (Gartenberg, Nessim, Cho): Comprehensive review of SI joint dysfunction pathophysiology, diagnosis, and treatment. Identified SI joint dysfunction as an “under-recognized source of low back pain” and recommended conservative management as first-line treatment due to lower complication rates than surgical alternatives.
What this means in plain terms: The medical literature says SI joint problems are being missed. Conservative care (including manual therapy) should come first. Surgery has higher complication rates and should be a last resort.
Full study: PubMed PMID 34272605
Journal of Physical Therapy Science, 2021 (Kamali et al.): Found that manual therapy combined with specific sacroiliac and lumbar exercises is effective for SI joint dysfunction. Adding targeted exercises to manipulation further increased long-term effectiveness.
What this means in plain terms: Adjustment alone helps. Adjustment plus targeted exercise works better. That is exactly the approach I use at Vanguard Chiropractic: restore the joint motion, then build the stability to keep it.

How I treat SI joint pain at Vanguard Chiropractic
Treatment depends on whether the joint is hypomobile (locked) or hypermobile (loose). The approach is different for each.
For a locked SI joint (hypomobility)
The goal is to restore motion. I use a side-posture adjustment targeting the SI joint directly. This is a low-amplitude, high-velocity thrust that gaps the joint and restores normal arthrokinematics. I also work the piriformis, gluteus maximus, and multifidus with pin-and-stretch technique to release the muscle guarding that developed around the restriction.
Most patients with a locked SI joint feel significant relief after the first adjustment. The deep ache lifts. Transitions (sitting to standing) get easier. Here is what happens mechanically during an adjustment.
For a loose SI joint (hypermobility)
You do not adjust a hypermobile joint. That makes it worse. The goal here is to stabilize. Treatment focuses on the segments above and below (lumbar spine, hip joints) to ensure they are moving properly so the SI joint does not have to compensate. Soft tissue work addresses the muscles that are overworking to stabilize the loose joint.
The rehab component is critical for hypermobile SI joints. I prescribe exercises that specifically train the deep stabilizers: bird-dogs, dead bugs, side-lying clamshells, and single-leg bridges. These fire the muscles that should be holding the SI joint stable.
Exercises for SI joint pain
These four exercises target the stabilizers that protect the SI joint. Start with bodyweight only. Do them daily.
- Bird-dog. On hands and knees, extend the opposite arm and leg simultaneously. Hold for 5 seconds. 3 sets of 10 each side. This trains the multifidus and gluteus maximus to co-contract across the pelvis.
- Side-lying clamshell. Lie on your side, knees bent 45 degrees. Open the top knee while keeping feet together. 3 sets of 15 each side. This fires the gluteus medius, which controls pelvic stability in single-leg stance.
- Supine bridge with squeeze. Lie on your back, knees bent. Place a ball or folded towel between your knees. Squeeze and lift your hips. Hold 5 seconds at the top. 3 sets of 12. The squeeze activates the adductors, which help compress and stabilize the SI joint.
- Dead bug. Lie on your back, arms straight up, knees at 90 degrees. Lower one arm overhead while extending the opposite leg. Return. Alternate sides. 3 sets of 8 each side. This trains the deep core to stabilize the pelvis under movement.
Red flags: when SI joint pain is not just joint dysfunction
Most SI joint pain is mechanical and responds to conservative care. But some symptoms require urgent evaluation.
- SI joint pain with fever and chills. This raises concern for sacroiliitis from infection (septic arthritis). This is rare but serious.
- SI joint pain in a young male with progressive morning stiffness lasting more than 30 minutes that improves with activity. This pattern suggests ankylosing spondylitis, an inflammatory condition that needs rheumatology evaluation.
- Progressive numbness or weakness in one or both legs. This suggests nerve involvement that may extend beyond the SI joint.
- SI pain after significant trauma (fall, motor vehicle collision). This could indicate a pelvic fracture that needs imaging.
If any of these apply, I refer out. Here is how to know when you need a doctor versus a chiropractor.

SI joint pain and pregnancy
SI joint pain is one of the most common complaints during the third trimester and postpartum period. The hormone relaxin loosens the ligaments that hold the SI joint stable. Add the weight of pregnancy, the shift in center of gravity, and the biomechanical changes of carrying a baby, and the SI joint gets overloaded.
During pregnancy, I use modified techniques (pelvic balancing, side-posture adjustments with pregnancy pillows) that are safe for expecting mothers. After delivery, the focus shifts to restoring ligament tension and rebuilding the core and pelvic floor stabilizers.
Prenatal chiropractic care in Tulsa and postpartum chiropractic care both address SI joint dysfunction as a primary concern. I adjust pregnant women and new moms at Vanguard Chiropractic regularly.
After the Pain Goes Away: Why Ongoing Care Beats Crisis Care
If your SI joint pain has come back more than once, the mechanical pattern that caused it is still there. Treating only when it flares means treating the same problem repeatedly while the underlying restriction compounds. The honest clinical recommendation for recurring SI joint pain is ongoing weekly care for at least 12 weeks after the acute phase resolves, then tapering to whatever cadence your spine actually needs.
That sounds like a lot. It is not a sales pitch. It is what your spine needs to actually change the pattern. Each flare leaves the system slightly more guarded than before. Pretending otherwise is what leads to the chronic-pain version of this story 5 years from now.
The brand stays exactly the same. No contracts. No packages. No prepaid plans. $40 every visit. Stop coming whenever you want. The decision is yours, every visit. We just tell you the truth about what your spine needs and let you choose. Most patients who genuinely commit to the 12-week rebuild come back less often per year than patients who only show up when the SI joint flares.
Frequently asked questions: SI joint pain chiropractor in Tulsa
How do I know if my pain is SI joint or sciatica?
SI joint pain is typically a deep ache at the top of the buttock that gets worse with transitions (sitting to standing). Sciatica is sharp or electric and typically runs below the knee. I test for both on the first visit using a cluster of provocation tests for the SI joint and nerve tension tests for sciatica.
Can a chiropractor fix SI joint dysfunction?
For hypomobile (locked) SI joints, chiropractic adjustment restores motion and provides significant relief. For hypermobile (loose) SI joints, treatment focuses on stabilization through targeted exercise and addressing the surrounding joints. Both patterns improve with conservative care.
How many visits does SI joint treatment take?
A locked SI joint often responds in 2 to 4 visits. A hypermobile SI joint takes longer because it requires building muscular stability, typically 4 to 8 visits over several weeks. More on adjustment timelines.
Is SI joint pain common after having a baby?
Very common. Relaxin loosens the pelvic ligaments during pregnancy, and they do not always return to full tension after delivery. Postpartum chiropractic care specifically addresses this.
Can I run with SI joint pain?
It depends on the severity. Mild SI dysfunction may allow modified running. Significant SI pain that alters your gait should be treated first. Running with an unstable pelvis creates compensations that lead to secondary problems in the hip, knee, or opposite SI joint.
Do I need imaging for SI joint pain?
Usually not. SI joint dysfunction is diagnosed clinically through provocation tests. Imaging (X-ray or MRI) is needed if I suspect fracture, infection, inflammatory arthritis (like ankylosing spondylitis), or if conservative treatment is not producing improvement after several weeks.
How much does it cost?
$40 per adjustment. Cash pay. No insurance billing. More on costs.
