I have this exact same curvature of the spine. I also curve inward. I am decades older than you and it has yet to cause an issue. So, for many, they never have any problems. Exercise is awesome and helps keep it all healthy and moving. So, keep that up! Remember that scoliosis is very common with almost 7 million people in the states having it to some degree. Normally with levoscoliosis, they wait and watch. Sometimes it can cause problems over time (often it doesn't). I'm personally not a fan of invasive surgeries like spinal fusion but if you begin to have lots of issues, then that can be looked at. This is where they straighten the spine to get rid of the curves. Do you have any discomfort at all? https://www.healthline.com/health/levoscoliosis#treatment
