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
If a scoliosis curve gets worse, the spine will also rotate or twist, in addition to curving side to side. This causes the ribs on one side of the body to stick out farther than on the other side. Severe scoliosis can cause back pain and difficulty breathing.
