The last time I visited this site it was before my antererior and posterior l4l5 fusion surgery..that was almost a year ago.. This site offered me so much info before my surgery... I'm now returning for guidance. 11 months post surgery I slipped and fell on ice and I'm scared that the fusion was messed up. I feel pain in my low back, tail bone area. It's been a week since the fall and I'm feeling pain like I had pre surgery... So discouraged.
