ALLEVIATES JOINT PAIN AND REDUCES SI JOINT INFLAMMATION - Vriksasana SI joint belt helps stabilize the sacroiliac joint (or "SI joint") that is hypermobile or inflamed, and reduces pelvic, lower back and/or leg nerve pain (symptom of sciatica) caused by SI joint dysfunction. We strongly recommend that you wear the Vriksasana SI joint belt day and night for at least two weeks. Do not over tighten the belt.
