How SI Joint Pain Is Treated: Physical Therapy, Stabilization and SI Joint Injections Explained

SI Joint Pain Is Treatable Once You Understand the Root Cause

One-sided low back pain can feel like a mystery, especially when you’ve already tried stretches, exercises, or medications with no real change.

But here’s the good news:
Once the SI joint is correctly identified as the pain source, everything gets clearer.

At Vertrae®, we see this scenario all the time. People come in frustrated, but once the diagnosis is right, the treatment becomes simple, strategic, and most importantly, effective.

The two core tools we use are:

  • Targeted physical therapy to restore pelvic stability
  • SI joint injections to reduce inflammation and confirm the diagnosis

Let’s walk through how each one works and how we build a plan that fits your life and movement goals.

Why SI Joint Pain Doesn’t Respond to Generic Back Exercises

Most spine rehab plans are built around disc or facet joint issues. Not the SI joint.

That’s a problem, because the SI joint doesn’t want flexibility, it wants stability.
Too much movement in the wrong place is what causes pain.

That’s why traditional “low back” exercises often fall short.
Instead, SI joint dysfunction responds best to:

  • Rebalancing the pelvis
  • Strengthening the glutes and deep core
  • Addressing everyday habits that overload one side of the body (like crossing legs or standing unevenly)
  • Teaching your body how to transfer load symmetrically again

This is where SI-specific physical therapy shines.

What SI-Focused Therapy Actually Looks Like

Stabilization comes first.
We begin with movements that help the pelvis stay aligned and controlled, things like bridges, clamshells, or side-lying hip work.

As your body relearns how to stabilize, we layer in strength, especially for the glute medius and deep abdominal muscles. These areas are often weak in patients with SI joint pain, causing the joint to bear too much strain during daily activities like walking, standing, or lifting.

From there, we address hip mobility and walking mechanics. Why? Because even a small pelvic tilt or limp can irritate the SI joint again and again. Fixing your stride and posture makes long-term relief possible.

Finally, we train the core to support load transfer, so the SI joint isn’t doing all the heavy lifting between your upper body and legs.

Manual therapy, such as soft tissue release or alignment work, may help in the short term, but lasting improvement always comes from stability, not manipulation.

When Injections Help Move Things Forward

Sometimes the SI joint is too inflamed or irritated for therapy alone to work.

That’s when an injection can provide just enough relief to make progress possible.

At Vertrae®, SI joint injections are done under precise imaging guidance to ensure accuracy. A small amount of local anesthetic and steroid is placed directly into the joint space.

Patients often notice:

  • Reduced muscle guarding
  • Improved ability to sleep
  • Less pain during movement
  • Greater success in physical therapy

Relief can last anywhere from a few weeks to a few months, sometimes longer.
But even short-term relief can open the door for long-term success through therapy.

The Difference Between Diagnostic and Therapeutic Injections

We may use injections in two different ways:

  • Diagnostic: If the pain disappears briefly after a numbing injection, that’s a strong indicator the SI joint is the true source (not the disc, hip, or nerve root).
  • Therapeutic: Steroids added to the injection can help reduce inflammation, ease symptoms, and help you progress in therapy.

This dual-purpose approach helps us move forward with confidence.

Who Typically Benefits From a SI Joint Injection?

You might be a good candidate if:

  • Your pain sits low and off to one side
  • It’s worse with standing, walking uphill, or turning in bed
  • You’ve tried therapy but haven’t made full progress
  • Imaging doesn’t explain your symptoms
  • Your exam points toward SI involvement

In these cases, a well-timed injection can be both clarifying and relieving.

What If the Pain Keeps Coming Back?

For most people, a combination of therapy and one or two injections is enough to restore function and reduce pain. But if your symptoms persist, despite doing all the right things, we may discuss minimally invasive SI joint fusion.

This isn’t where we start. But when needed, it can be life changing.

Vertrae® uses a modern, outpatient approach that stabilizes the joint using tiny implants, reducing painful micromovement without compromising your ability to move freely.

It’s a thoughtful, low-impact solution that preserves motion in the rest of your spine.
