I too had an operation for a disc. In fact my disc broke finally as it was not diagnosed in time. It took a very long time for me to be able to walk more than a few steps, and I too had numbness of the foot and thigh. It is not perfect by any means, but I did go on improving for several years. In fact when I was told by doctors that that was all the improvement I would get, I still went on getting better very gradually. I know everyone is an individual, but be hopeful, it will get better. As for walking, I made myself walk but only what I could manage comfortably, a few steps at first improving gradually. If you dont walk your tendons will shorten and you will get trouble. You must have been given exercices, also I have a Pilates machine which is wonderful for stretching and strengthening, but you must ask your practioner when the time is right to use it. Good luck.
