The shape of a normal spine is straight up and down when viewed from the back. From the side, it naturally curves into an S-shape.
When the spine curves more than 10 degrees, doctors may diagnose scoliosis, a side-to-side curvature of the spine. Symptoms of scoliosis include back pain, uneven shoulders, and an appearance of leaning to one side.
