What is causing my uneven skeletal structure?

It may be scoliosis. I have it. The right side of my body is lower then the left. It happens during development due to poor posture, odd sleeping positions, and other things. You will need to see a doctor if you are too twisted they may put you in a brace but don't worry I'm pretty crooked but they haven't braced me. They just told me to try to stand up straight.
