dear Caz,
I always recommend my patients to read as much about their problems as possible. Here are some sites:

Scoliosis - Have questions about Scoliosis? iScoliosis.com has answers.
National Scoliosis Foundation
Scoliosis World
Scoliosis Association (UK)
http://www.scoliosis-assoc.org/

I am sorry to tell you that research is currently showing that most adult Wikipedia reference-linkscoliosis curvatures tend to progress with age and that keeping up your exercises and good posture is very important.
For a good review on the pathological process and implications, in early years and in adult life go to Scoliosis | Full text | The transformation of spinal curvature into spinal deformity: pathological processes and implications for treatment. I am sorry, this is not an easy article for laymen, maybe your therapist will be interested.

kind regards
Esther de Ru
