I was curious to how many of you who have had unsuccessful fusion of lower lumbar and sacrum area continued to smoke during the recovery process and/or were overweight and/or waited more than six months to have your surgery. I am about to undergo a fusion of lumbar 5 and sacrum 1. I am a non-smoker since August, a bit well-nourished in the abdomen and have experienced severe sciatica pain less than six months. I added a few other poll response choices.
