Fisher Glad to hear all went well. I had what sounds like the same thing in 2000. The recovery takes a while. Now I know different doctors have different outlooks but mine had me do a lot of walking. Like The day after surgery I had to walk one hall of the hospital and the next day the loop and on day 3 went home then by end of week 1 it was 1 mile a day and at week 2-3 it was 2 miles. My doc didn't have me go to a Physical TERRORIST he just had me do lots of walking. I would guess your repair was at L4-L5 that was mine and the most common. It will never be as good as new but if you get pain relief and it is better than before surgery that is about the best you can hope for on this kind of stuff.
Good luck and take care.
