This is a structural problem. We're not doctors here. You have doctors. They're the ones you should be asking. I assume if there are any exercises for this problem you will be sent to physical therapy. Also know that having this condition doesn't necessarily mean you'll have any pain from it -- that's an individual thing, and many people who have structural problems are really feeling muscle problems when they have pain, not necessarily the pinching of nerves and the like that comes from structural problems. But you need to see medical professional for this one.
Not that this will work for everyone, but the best treatment I ever had for my (slight) scoliosis causing hip, knee and back pain was "Schroth Therapy", which helped me learn to breathe into the concave side of the body. This element of Schroth Therapy is known as "Rotational Angular Breathing". Recommended by my orthopaedic specialist and took a while to get the hang of after tracking down a physiotherapist versed in the technique. There appear to be a few videos of the technique if you google "Schroth Therapy".
