I am facing an upcoming lumbar fusion on L5S1 and possibly L4-5. My surgeon has told me what kind of pain to expect and suggested that I research and learn as much as I can about the procedure. He also told me to compile a list of any questions I have. I have suffered from post laminectomy changes and epidural fibrosis since 2002, 1 year after my initial surgery. I have been reading some of the posts and now realize how much I don't know about this procedure. Any help or suggestions would be greatly appreciated.
