Been through it. Sorry it is rough. I have had that widespread numbing experience when I also had my spine rearranged and made with metal. My entire lower back was numb. Five or six years post (and I also had hip replacement prior to the spine). It is a slow recovery, but based on my experience, do not put a stop watch on it, do the best that you can and in my case several years for it to come 95% back (but I am old and was old already). Compliance with doctors, watch pain killers, and most importantly lifestyle stability: sleeping, eating, bathing, distraction instead of concentrating on your loss of functioning or sensation. Anyway, good fortune and best of health to you.
