When someone says, “My lower back feels stuck,” or “It hurts right at the belt line,” there’s a good chance the sacroiliac (SI) joint is involved. The SI joints sit on both sides of your lower spine, connecting the sacrum (the triangular bone at the base of your spine) to the pelvis.
These joints don’t move very much—only a few millimeters—but that tiny motion plays a big role. The SI joints help absorb shock between the upper body and the legs and keep your pelvis stable when you walk, bend, lift, or twist. Because they’re so central to everyday movement, even small dysfunctions can make a big impact.
When the SI joint isn’t moving the way it should—either too much motion or not enough—you might notice symptoms like:
-
A sharp, aching, or stiff pain in the low back or buttock
-
Pain that radiates into the hip, groin, or down the leg
-
Trouble standing up from a chair or rolling over in bed
-
Pain when walking uphill or climbing stairs
-
A feeling that your pelvis is “uneven” or out of balance
One tricky thing about SI joint issues is that they often mimic other conditions, like sciatica or lower back strain. Many people assume the problem is their lumbar spine, when the real source is the joint just below it.
I see SI joint dysfunction often in people who sit for long periods, runners, people who’ve had pregnancies, or those with old injuries that changed how they move. When the muscles around the pelvis become tight or weak, or when one side of the body starts doing more work than the other, the SI joints can become irritated and inflamed.
A chiropractic approach looks closely at how your pelvis and lower spine are aligned, how each SI joint is moving, and what’s happening with the surrounding muscles. With gentle adjustments, soft tissue work, and exercises to support pelvic stability, we aim to restore healthy motion and reduce strain on the joint.
SI joint dysfunction can be frustrating because it affects so many daily movements, but it’s also very treatable. With the right care and some simple posture and movement habits, most people find relief and feel more balanced and supported through their lower back and hips.
