The reason for my brace: I sat on a pillow and it slipped and I fell on my back. I had low back pain and sciatic pain first on my left side then on my right side. I was in the infirmary for 4 weeks each time with low back pain and sciatic pain. After wearing the brace I was able to walk better and with some comfort. I wear the brace from 5:30 AM until 7:30 PM daily. I have used it daily since I received it and feel it has helped me a lot.
