Stretching Exercises for SI Joint Pain

If you’re experiencing discomfort in the lower back, buttocks, or along one side of the pelvis, the sacroiliac (SI) joint may be the source. This guide explains the best stretching exercises for SI joint pain, what triggers SI joint irritation, and how simple daily movements can improve your symptoms and support long-term recovery.

Understanding the SI Joint

The sacroiliac (SI) joint connects the sacrum—the triangular bone at the base of the spine—to the ilium of the pelvis. Although this joint is small, it plays a large role in stability, weight transfer, and overall posture.

When the joint becomes irritated or inflamed, you may feel:

• Lower back pain

• Buttock discomfort

• Pain during standing, walking, or twisting

• Stiffness after long sitting

• Difficulty bending or rising from a chair

Activities That Commonly Aggravate SI Joint Pain

The following daily habits or movements can overload the SI joint and worsen inflammation:

1. Sitting for Long Periods

Soft sofas or non-ergonomic seats compress the pelvis and increase strain.

2. Improper Lifting Technique

Lifting heavy items without proper form stresses the lower back and SI joint.

3. Repetitive Twisting Movements

Common in sports like tennis or golf, as well as in household chores.

4. High-Impact Exercise

Running, jumping, or intense workouts may exacerbate pain during flare-ups. exacerbate 

5. Prolonged Standing

Especially on hard surfaces, it can fatigue the pelvic stabilizers.

6. Poor Posture

Slouching or uneven weight-bearing can misalign the pelvis.

7. Pregnancy-Related Changes

Hormonal relaxation of ligaments increases joint mobility, which may cause pain.

8. Trauma or Falls

Sudden impact or twisting injuries can irritate the joint.
