i had the lower spine fused in 2004. it hurts like a total biatchhhhh after the surgery but it gets better. and they gave me morphine. my surgery worked i like i had the L4 or whatevers fused hahaha i don't know which spine disk thingies they were but it was the lower back. i have aches everyday but they go unnoticed for the most part. you will be fine! sounds like something you have to do anyway.. if you have scoliosis.
