I've had scoliosis, took 2 years to heal. I have to tell, you're going to need an orthopaedic corset, there's no way it's gonna go away with just pilates and posture exercises. So save a bit of money for that, they're not very expensive, usually they are around 200-300 at least where I live. After that, it's highly unlikely it will come back😊 Ask your doctor if you'll need a full one (neck included) or just to cover the bust, and ask for shops where to buy it. Hope this helped!
