The Bottom Line
SI joint pain is common and often responds well to a combination of gentle mobility, stretching, and core/hip stabilization exercises. The key is consistency and avoiding aggravating positions. Most cases improve within 6-8 weeks of dedicated treatment. Focus on balanced strength around the pelvis and mindful movement patterns.
