never a fan of back braces as they are used to compensate for strength/core stability that you don't have. If it's an acute injury, then a back brace might help to relieve some pain and allow the tissues to recover. However, using a back brace on a regular basis only further weakens your core strength as eventually you will rely on the back brace for your support rather than yourself.
Agreed with stretching, rest, and listening to your body....
