Back Braces: Buy one / build one
Back braces can be very helpful. In normal, pain-free spines, muscles hold the spine in place. But when the spine is injured or unstable, muscles tighten to protect the spine (its called muscle splinting). When those muscles have to stay tight for long, they ache and fatigue. If they are tight long enough they can even cramp or burn. Exercises retrain the muscles to support the spine
