I'm sorry you've gone through that and I hope your condition improves. While I don't know the specifics of your case, in general there aren't a lot of real solid evidence-based medicine guidelines for treating back pain or injuries. Ask 10 different physicians and you'll get 10 different treatment plans. Surgery has made many patients worse in the long run. Obviously there are some traumatic injuries where emergency surgery is medically necessary, but for most patients the standard of care should be physical therapy first with surgery being a high-risk last resort.
