Review on Sacroiliac Support SI Loc Hip Belt - Small/Medium - Men and Women's Lumbar Lower Back Joint Pelvic Posture Support by Ruben Saunders

My husband wears this belt. The relief was immediate. Pain in the sacrum, which haunted him for 6 months, after 10 days went down to almost zero. He needed a guide on how to wear it and he got it on YOUTUBE. It seems most effective to wear between the top of the femur and below the top of the thigh crest (pelvic bone?). The strap needs to be adjusted from time to time because it tends to slide up after an hour or two.
