Good grief ~ I would find the best spinal surgeons and get at least two more opinions. Back surgeries of any kind are the work of the devil and lead to more and more surgeries. Some of them not even necessary.
You don’t day anything about Physical Therapy or supervised exercising. This is the big key to pain relief and back strengthening. Pilates a little bit at a time is a great way to start. But do a lot of questioning before you do anything !!!!!!
