My daughter had scoliosis surgery ten years ago when she was 15. Her spine had a 30 degree curve. The surgery went well, she gained an inch in height and is now straight as an arrow. As the surgeon predicted, she experienced exactly two weeks of a few back spasms and a some pain that was alleviated by relaxants and pain medication. She has had no trouble since.
Unfortunately, I'm 58 and getting conflicting info on surgery.....can't because of age and osteopenia , should because it will alleviate pain, can't because of having 2 problems (curvature and disks). *sigh*
