I just posted this here on something similar:
"I suggest seeing a couple more Spinal Surgeons. I saw 4. They all had a different idea - from nothing to fusing my entire back! Get more info. I was VERY pleased with my L3,4, 5 fusion and got my life back. It should all depend on something simple like an xray! Believe it or not. A good orthopedic spine surgeon can see about everything he needs to know from an xray. I will need more surgery but I had wanted to keep my mobility so we "settled" on what worked best for me. Its been 8 years. Happy as a clam. If you can get to UCSD orthopedics, they are tremendous!"
I have degenerative disc disease and I have scoliosis. My surgery repaired some of both. I am a big proponent of surgery IF you have done your due diligence, researched and tried everything and gotten several opinions. Once the correct doctor entered my life the decision was a piece of cake!
