Hello,
Sorry to hear you are going to have another surgery. So far I'm in the first stages of finding out just what action to take. I have a bulging disk laying on a nerve root. Stenosis, 6 verterbra in lower lumber instead of 5 hooked to the sacrum causing even more pain, anyway as to your question about going numb, it struck me because just last week I was getting groceries out of the car. Well, Iwas already down the last step, I had my footing but then my whole left leg went numb and my left foot just sort of dropped to the side and down I went landing on my right knee on rocks and cut it up. It was not a good feeling, I hope the best for you.
