By Mayo Clinic staffThe spine is an elegant structure — from the side it takes the form of an elongated S, the upper back bowing outward and the lower back curving slightly inward. Viewed from behind though, the spine should appear as a straight line from the base of the neck to the tailbone. Scoliosis is an abnormal curvature of the spine.
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
- Leaning to one side
- Fatigue
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.
