Have you been doing a home exercise program (HEP) your entire life? With your early diagnosis of scoliosis you should have begun a HEP then. I too was diagnosed early and now have a compensating curve in bot my lumbar and thoracic spine, they kind of even each other out. They are minor compared to my spinal stenosis, lower extremity peripheral neuropathy and chronic pain so you’re in good company. I had surgery in 1988 and it allowed me to continue my life and work. I couldn’t go back to being a nurse but I stayed in the healthcare field. Deciding for surgery is a big decision and I would exhaust all other avenues first and obtain second opinions. You said your tried everything else so choose who will perform it wisely. You can find recommendations on this site for certain.
