Will my scoliosous get worse?

You'll probably be fine. The only other thing you can do is check with a good chiropractor and make sure to keep your back muscles strong. Anybody that works with biomechanics and body alignment should be able to help you. (That goes for anybody though, so don't let seeing an alignment specialist scare you. Lots of people have issues like this. Taking care of it now will improve health in the long run.)
