Hi ch47,
My procedures (rhizotomies) were L4 through S3.
One of my "dressing room pals' said that one time, her procedure did not work, but the other times did.
It can take time to get to the point where all the recovery discomfort is gone.... but I found those days were still better than the 'before days'... but it is good to keep that balanced perspective, because, " the best laid plans.." keeping expectations modified by all the possibilities is wise.
Certainly it guards against great disappointment and despair, to not get too far ahead of sober reality.
Good your doc is keeping a lid on it. Yes, the physical preparation is very important, but the biggest challenge is the mental prep.
Balance is key.
Hope your day is going well (and no smoke!).
