There are several types of back braces available at CVS, including waist belts, posture correctors, and back stabilizers to help provide lumbar support. You should determine which type is best for your specific back pain by asking your doctor. A posture corrector can be worn daily to help you sit or stand up straight, while a medical back brace is designed to assist with healing after surgery or while dealing with back pain and minor injuries. To wear a back brace, position it over a tight-fitting shirt made of cotton. You can add another shirt over the brace if you want to conceal it. Adjust the back brace until it's tight enough to provide ample support, but not so tight that it feels restricting or uncomfortable.
