Your life is definitely not ruined, and yes, there are exercises you can do to help. If your insurance company will send you to PT, they can teach you some good core strengthening exercises that will help you a lot. Did your doctor do a hand x-ray on you? The hand x-ray can tell your bone-growth age. When my son was diagnosed, he was just watched for a while. When he got worse, he had the hand x-ray, which showed his bone growth age at 14 1/2 years, even though he was 15 1/2. That's how they can tell if you're finished growing. He is now 18 and has a 35 degree curve, but he has little to no pain from it. He wore a hard plastic brace for several years for 12 hours a day. That may have kept it from getting worse. I have a 75 degree curve, so the severe type runs in our family. Your curve is so mild, though, I'd be very surprised if they would want to put you in a brace. You probably don't have too much more growth to come. If you get some good PT, that may be all you need. I would try to find someone who specializes in scoliosis cases. I had PT before my surgery, and although I liked the guy, I think some of the exercises he had me doing actually made me worse.
Don't despair. You still have lots to look forward to in life. If you get some good exercises and then DO THEM REGULARLY, that will help with your pain. Ask your doctor whether Ibuprofen or Naproxen Sodium would be better on your bad days, and how much, or if he would recommend something else. Heat or ice may also help. You may need to learn how to modify some of the things you do to put less stress on your back, but a mild scoliosis won't keep you from enjoying sports and other activities.
Good luck! SounRAB like you're getting good care. Do make sure your doctor keeps an eye on your scoliosis in case it does start getting worse. And come back and ask whatever questions you may have.
Blessings,
