For the past 3 years I have been plagued with severe pain radiating down my sciatic nerve, front thigh and hip joint. Last Christmas I was on a walker as the pain was so severe. This past summer I was sent to an orthopedic surgeon who said I needed a complete hip replacement as I have a bone spur on the femur.? This also prevented me from golfing (a passion of mine) and from walking my dogs properly. Since using the wrap for the past 10 days I am in far less pain and am up to the third level 3-4 times a day. I will continue faithfully as I do three areas each day, Piriformis muscle at the back, my front thigh and sciatic regions. Erica from California
