What complications can arise from minor scoliosis, spine curvature?

Progression: A truly mild scoliosis usually is almost completely asymptomatic and does not cause any problems. The only significance of a mild curve is that, if the person is still growing, the curve can progress, and so should be followed. Thank you for the question.

Idiopathic scoliosis: Idiopathic (spontaneous without a cause) scoliosis is not a painful condition. Back pain in scoliosis is similar to that of people with a straight spine unless lumbar curves exceed 30-50 degrees and thoracic curves exceed 50-70 degrees. Curve progression occurs with aging by about .5 degree per year. It is not likely to "compress organs" or cause breathing, heart or neurologic probs unless severe.
