yes they do i had to wear one for two months because of lower back pain. ordered by my doctor who preformed back surgery on me two months later. he said if the brace works to reduce the pain then surgery will fix the problem. but if that brace changes nothing with your pain no surgery in the world will fix your problem. so give it a try what could it hurt. also while i was a mail carrier i wore one. it really took the weight of my back.
i have increasing lower back pain and wonder if those special belts and posture aids ever help. i have some arthritis in my spine some scoliosis and many of my disks are partially herniated. two years ago i had a cyst and partial herniation on a lower disk and my back "went out" when i picked up a child from the floor. i had about 3 months of pretty severe pain in my left foot. i'm pretty active but it hurts most when i sweep vacuum or stand preparing food at a counter for a long time. by the way i'm 66 and female. thank you!
