Why Your SI Joint Keeps Causing Pain
You treat your SI joint pain. But days later, it's back again.
Maybe you've tried stretching, strengthening exercises, or even chiropractic adjustments. You've done hip flexor stretches. Glute bridges. Pelvic tilts. Every video promises relief, but the pain keeps returning.
By the end of the week, that familiar ache in your lower back is creeping in again. Your pelvis feels unstable. Your hips feel tight. And no matter what you do, it feels like your body is fighting against you.
If this sounds familiar, you're not alone.
Most people think SI joint pain is just a structural issue—something you can fix with the right stretch or adjustment. So they keep targeting the same area. But the truth is, if your SI joint keeps flaring up no matter what you do, the root cause might be hidden somewhere completely different.
What if it's not about the joint at all… but about how your brain interprets signals from your body?
In this guide, we'll show you why three simple exercises work when nothing else has and why real SI joint relief starts with addressing the foundation, not just the symptoms.
If you're tired of the endless cycle of pain and temporary relief, this might finally connect the dots.
Understanding SI Joint Anatomy
Now that we've addressed the frustration—the endless cycle of pain and temporary relief—it's time to look under the hood.
Your sacroiliac (SI) joint is one of the most critical stabilizers in your body. It connects your spine to your pelvis and bears tremendous load with every step you take.
At the heart of SI joint function is a complex interaction between stability and mobility. The joint itself has minimal movement—only a few degrees of rotation and translation. But this small amount of movement is crucial for proper weight distribution and shock absorption.
The SI joint is supported by some of the strongest ligaments in the body:
Posterior Sacroiliac Ligaments: These provide the primary stability for the joint and resist forward movement of the sacrum.
Interosseous Ligaments: Located deep within the joint, these ligaments prevent excessive movement and maintain joint alignment.
Sacrotuberous and Sacrospinous Ligaments: These connect the sacrum to the pelvis and help control pelvic positioning.
Iliolumbar Ligaments: These connect the spine to the pelvis and influence SI joint mechanics through their effect on lumbar positioning.
But here's the problem: most treatment approaches stop here.
What they miss is that the SI joint doesn't function in isolation. It's part of a larger system that includes your feet, pelvis, spine, and even your visual system. When any part of this system sends faulty information to your brain, it can create compensations that place abnormal stress on the SI joint.
If you've been focusing on isolated SI joint treatments, but your foundational stability is off, your results won't stick.
What's Really Driving SI Joint Dysfunction?
It's easy to blame an old injury or sudden movement. Yes, trauma can trigger SI joint problems. But that's often just the final straw.
What's rarely talked about is how the brain adapts to subtle imbalances throughout your body and starts reinforcing dysfunctional patterns as the "new normal."
Here's what happens:
When your feet lose their stability, your pelvis compensates. When your pelvis tilts or rotates, your SI joint bears uneven load. Your brain—always trying to maintain balance—reinforces whatever pattern keeps you upright, even if that pattern creates pain.
Over time, the muscles meant to stabilize your pelvis get confused about their job. Some become overactive and tight. Others shut down and become weak. This is where SI joint stiffness, inflammation, and chronic pain begin.
So fixing SI joint dysfunction isn't about manipulating the joint or just doing hip stretches. It's about retraining the sensory systems that control pelvic stability and restoring proper movement patterns from the ground up.
As research shows, when the brain misinterprets signals from your body, it can lead to imbalances that place pressure on areas like the SI joint. If this joint becomes misaligned due to postural issues, no amount of massage or bodywork alone will correct the cause of the SI joint pain.
Now that you understand the deeper cause, let's move into the 3 exercises that actually start fixing it from the foundation up.
Note that aggressive stretching or heavy resistance is not necessary for these exercises. You'd be surprised how effective gentle, controlled movements can be when they target the right systems.
Three Exercises for SI Joint Relief
1. Pubic Symphysis Exercise
Here's how to do it:
- Lie on your back with your knees bent and your feet flat on the floor
- Place a softball or rolled up pair of socks between your knees
- Very gently squeeze the ball for a count of 5, then slowly release
- Perform 3-5 repetitions, but let your pain be your guide
- Focus on gentle activation rather than maximum force
Safety Note:
This exercise should feel gentle and comfortable. If you experience sharp pain or significant discomfort, reduce the pressure or discontinue the exercise.
2. Advanced Quadriceps Stretch
Here's how to do it:
- Lie on one side with your bottom leg slightly bent for stability
- Grasp your top foot, ankle, or shin behind you
- Gently pull your foot toward your glute
- Hold for 30-60 seconds, breathing deeply
- Switch sides and repeat
- Focus on releasing tension in the front of your thigh
Safety Note:
Avoid pulling aggressively. The stretch should feel comfortable and sustainable. If you cannot reach your foot, use a towel or strap to assist.
3. Knee-to-Chest Stretch
Here's how to do it:
- Lie on your back with both legs extended
- Slowly pull one knee toward your chest, supporting it with both hands
- Hold for 30-60 seconds, feeling the stretch in your hip and lower back
- Release and repeat with the other leg
- For additional benefit, pull both knees to your chest simultaneously
- Breathe deeply throughout the stretch
Safety Note:
Move slowly and avoid forcing the stretch. Stop if you experience any sharp pain or significant discomfort in your lower back or SI joint area.
Progressive Training Schedule
Week 1-2: Perform these exercises daily, focusing on gentle movement and proper form
Week 3-4: Continue daily practice while monitoring improvements in pain and mobility
Month 2+: Maintain consistent practice while incorporating additional strengthening exercises as tolerated
Transform Your Posture and Fix SI Joint Pain
Struggling with SI joint pain, pelvic instability, or chronic lower back tension? The solution starts with your feet. Poor foot mechanics create imbalances that travel up the body, affecting pelvic alignment and placing abnormal stress on your SI joint.
Our Therapeutic Insoles activate foot receptors and realign posture from the ground up.
By correcting your foundation, you can:
- Reduce strain on your SI joint and surrounding muscles
- Improve posture and overall body symmetry
- Move with greater confidence and stability
- Experience lasting SI joint pain relief
Additionally, Therapeutic Insoles can prove beneficial in activating the glutes and enhancing stability and mobility.
When to Expect Results
Most people notice immediate improvements in stability and posture awareness when they begin these exercises consistently. The neurological benefits of proper SI joint positioning start working within the first week of practice.
Structural changes in muscle activation and joint alignment typically become noticeable after 2-4 weeks of consistent training. The key is understanding that you're retraining movement patterns and sensory systems that may have been dysfunctional for years, which takes patience but creates lasting transformation when done correctly.

What is SI joint syndrome and how does it affect the body?
SI joint syndrome occurs when the sacroiliac joint, located between the spine and pelvis, becomes irritated or inflamed. This condition often results from misalignments such as a rotated pelvis, which places uneven stress on the SI joint. Over time, this can lead to pain, stiffness, and limited mobility. Using Therapeutic Insoles can help correct these imbalances by stabilizing the foundation of your posture, reducing unnecessary strain on the SI joint and providing natural SI joint pain relief.
What are the most effective SI joint pain treatments?
SI joint pain treatment often includes a combination of targeted exercises, gentle stretches, and therapeutic interventions. The most effective treatments include SI joint strengthening exercises, SI joint stretches for pain relief, and postural correction with therapeutic insoles. Incorporating brain-based approaches, like improving body alignment and muscle activation, can provide long-term relief rather than just temporary symptom management.
Which SI joint stretches can help reduce pain?
Specific SI joint stretches, such as gentle hip openers, knee-to-chest exercises, and pelvic tilts, can alleviate tension in the area. The most effective SI joint stretches for pain relief include the Figure Four Stretch, Hip Flexor Stretch, and Piriformis Stretch. These stretches improve flexibility, reduce inflammation, and restore proper function to the SI joint when performed consistently and correctly.
How long does it take to see results from SI joint exercises?
Most people begin to notice improvements in SI joint pain relief within 2-4 weeks of consistent exercise and proper postural support. Significant changes in stability and pain reduction typically occur after 6-8 weeks of regular practice. Combining exercises with Therapeutic Insoles provides immediate postural support while your muscles strengthen and movement patterns improve naturally.
Can SI joint dysfunction be permanently fixed?
Yes! Sacroiliac joint dysfunction can often be permanently resolved by addressing the root causes - typically postural imbalances and faulty movement patterns. The key is correcting the underlying issues that created the dysfunction in the first place, rather than just treating symptoms. Therapeutic Insoles help maintain proper alignment while you strengthen supporting muscles and retrain proper movement patterns.
What makes SI joint pain worse?
Common activities that worsen SI joint pain include prolonged sitting, climbing stairs, running on uneven surfaces, and sleeping on your side without proper support. Poor foot mechanics and postural imbalances are often the underlying culprits that make these activities problematic. Addressing these foundational issues with targeted exercises and proper support can significantly reduce pain and prevent future flare-ups.
Conclusion
Fixing SI joint pain isn't about doing more treatments—it's about doing the right exercises that address the root cause. These three movements target the key systems that control pelvic stability and SI joint alignment, but remember that lasting change requires addressing your body's foundation.
When you combine targeted exercises with proper postural support through therapeutic insoles, you create a comprehensive approach that addresses both the symptoms and the underlying cause of SI joint dysfunction.
Start implementing these exercises consistently, and consider how your body's foundation might be contributing to your SI joint challenges. Your pelvis—and your entire body—will thank you for taking this holistic approach to healing and prevention.
