Bob, when I say that I can feel your pain, I really mean it! I have an L5/S1 disc problem, also. My back episodes are intermittent; most days I only experience numbness in my left foot. It sounds as if your condition is chronic, and is not responding to the stretching and exercising that benefits most people with "bad backs". You've made the right choice in picking surgery over suffering. It might be a good idea to have your surgeon fillet a fish in your presence, before you let him cut on your spine. Just a suggestion Best wishes for a quick recovery.
