Treatment

Any underlying causes will need to be treated.

The goal of treatment is to stop the curve from getting worse. Choices are:

  • Observing a mild curve for any changes
  • Over the counter pain relievers
  • Physical therapy to learn exercises that improve posture and ease back pain
  • A back brace to keep the spine in line

Surgery may be needed by people with severe symptoms and those who are not helped by other methods. The goal of surgery is to correct the curve. This is done with a metal rod, hooks, or screws.

Prevention
