i have been dealing with on/off back problems for 10 years. I try to work on my core but it seems when I do, it makes my back issues worse. I have mild 12-degree scoliosis, and I favor one quad. When I get crippling spasms, I usually need a brace to even walk. However i still hunch. Has anyone ever used a rigid brace for recurrent problems? I am trying to avoid drugs and surgery.
