After receiving my DDS brace and putting it on, I actually felt a difference in my lower back pain and hurting. A calmness was felt and my back was hurting less. I wear the DDS brace at least 2 times a day for 2 hrs at a time. I also wear my brace to do grocery shopping under my clothes. The DDS brace have brought me much relief from the lower back pain I was enduring before the DDS brace. I feel blessed to have this brace. Thanks!
