Signs and symptoms of scoliosis may include: 
Uneven shoulders
One shoulder blade that appears more prominent than the other
Uneven waist
One hip higher than the other
One side of the rib cage jutting forward
A prominence on one side of the back when bending forward
 With most scoliosis cases, the spine will rotate or twist in addition to curving side to side. This causes the ribs or muscles on one side of the body to stick out farther than those on the other side.
