What are the symptoms of scoliosis in teens?

Symptoms of adolescent scoliosis include a protuberant shoulder blade, a rib hump, one arm hanging lower than the other arm and asymmetry in the shoulders, states the University of Maryland Medical Center. Additionally, spinal protrusions are sometimes perceptible when the sufferer bends over. Scoliosis does not usually cause physical pain.

Scoliosis is a condition where the spine develops unnatural sideways curves, most likely in the thoracic and lumbar spinal regions, according to the University of Maryland Medical Center. The root cause of adolescent scoliosis is unknown as of 2015, although theorists have put forward nutrition, genetics and sub-clinical poliomyelitis as possible origins.
