If nothing else, I have almost no pain while wearing it, no muscle spasms either. Have two just in case one gets damaged. I wear it over a t-shirt, just inside my jeans with my belt cinched snugly to keep it in place. Work construction daily with it.
Saw you have some spine issues. Me too, but I have been able to avoid surgery for 40 years by using magnets. No joke, my current belt is handmade with 30 neodymium magnets. Can't leave home without it.
