I too had scoliosis. I was diagnosed at age 13, and gradually over the course of several years, my curve ended up at 72 degrees. I had corrective surgery 10 years ago, at the age of 24, and now am the proud owner of two rods in my back
I do recall some pain in my hip, about getting shorter I am not sure, I can tell you that I grew nearly two inches with the corrective surgery though. I stood tall and proud at 5 feet 1 inch pre-surgery, and I now stand 5 feet 2 and 3 quarters inches now.
I am sorry I couldn't help you more with your questions, but I would advise that you get yours rechecked. Keep me posted!!!!
