I had a similar progression of my scoliosis in my teens, and it was getting more painful. I stopped getting pain once I started seeing a chiropractor regularly, and I did some other things like yoga, stretching and taking classes in Alexander Technique that helped me ease the muscles when I started getting pain. Nowadays I don't get pain unless I really overdo it physically, and getting way too overtired for way too long also causes discomfort.

I do yoga from videos wayched on YouTube specifically for scoliosis. I also stretch everyday and night. Trying to be aware of posture is a big one. Not overdoing it though, listen to your body.

Doing exercises that pull your shoulders back instead of the hunched position you get with scoliosis helps, but you need to keep doing them. I stopped and they came back. But when I did do them I felt better after a few weeks.
