Hi, I am 4 mos out of a l4-l5 ALIF. I was kneeling the other day to see something and when I went to get up I lost my balance and twisted and sort of fell over to my right. Since then I have noticed my right leg falling asleep on me periodically. The only leg problems which were buring and twitching since my surgery have been in my left leg for which I was prescribed Neurotin. It has helped to some degree. Before I call my doc I thought I would put a post out for your comments??
