I also have an "S" curved spine. It was discovered when I was in high school. I went to an orthopedic doctor who took x-rays, and both curves were perfectly balanced and my vertebrae were level and even. Ironically I have never had to wear a brace. My doctor x-rayed by spine 10 years later and there had been no change at all. This can be considered good and bad. Bad in that nothing improved, and good that everything was still balanced and unchanged. I'm not sure if any of this helps you, but I thought I would reply. -W
