How you sleep matters when you have SI joint pain. Our La Cañada Flintridge chiropractors walk through the positions that help — and the ones to avoid.

If your SI joint pain is worst in the morning, your sleep setup is a huge part of the story. You spend a third of your life in bed — the position you're in matters more than any single stretch.

The sacroiliac (SI) joint sits between the pelvis and the sacrum. It doesn't move much, but when it does move wrong, the pain is unmistakable — sharp, deep, and often mistaken for sciatica.

The Best Positions for Si Joint Pain

Side sleeping with support: For most spine-related pain, side sleeping with a pillow between the knees keeps the pelvis level and takes pressure off the low back and hips. Add a small pillow hugged to your chest to keep the upper body neutral.

Back sleeping with knees supported: Also excellent — a pillow under the knees lets the low back settle into a neutral curve. A relatively flat pillow under the head keeps the neck aligned.
