How do you treat a 22 year old with a curved scoliosis or would you not do anything?

Depends. The treatment of scoliosis first requires a thorough evaluation and special x-rays. Treatment options range from simple back bracing to complex surgical treatments. The treatment type depends upon the degree of the spinal curvature and the severity of symptoms.
Depends. It depends on how "bad" the curve is ...You require an x-ray to really assess the severity of your curve...So see your orthopaedic spine specialist.
