A back brace can help if you're dealing with a herniated disc because it works to help support and stabilize the spine. While a back brace isn't the only treatment for a herniated disc, it might help to support the healing process. Some doctors will prescribe a back brace after surgery for a herniated disc or other issues such as acute sprains and injuries. If you have a herniated disc, be sure to talk to your doctor to find out whether or not a back brace is recommended, and which one is right for your unique needs.
