My doctor and I have decided that I will have the fusion surgery. I have to do an EMG, CT scan, flex xrays and return to him for discussion. What questions should I ask? He said that he would probably do TLIF. I have had several MRI's done and also had discectomy last year at the same level. I have pretty much constant pain for the last year. I have gone the route of epidurals and radiofrequency ablation. I have taken physical therapy and now this fusion. I can't say that I am scared because I just might just be pain free after this (of course I will have plenty of surgical pain). I can't understand why I am having a CT scan and EMG. My surgeon is ortho spine and I have a great deal of confidence in him. Any hints for questions or preparation would be appreciated. Thank you.
