How can i fic my lumbar prominence?

Scoliosis: What people call a lumbar prominence is also called scoliosis. The only FIX for this is to have surgery. While back braces and exercises may alleviate back pain, they won't straighten the curve in your spine, particularly not when you're already an adult. I would recommend you see an orthopaedic spine surgeon who has treated scoliosis previously. He or she can talk to you about risks vs. benefits.
