I am thankful for the DDS brace. It has helped me so much. My stomach is a little large which caused me to be short of breath a few times but I compensated by dropping the air pressure a little. I really like the brace—the lessening of the pain is wonderful. I had a lumbar laminectomy on two different occasions. The first lasted about 10 years. The incompetent surgeon who did the last on really messed my back up. I can no longer run or bend over without pain. The back brace relieves the pain very much, but I still can’t run like I formerly could.
