I had a discectomy (lower back) four days ago. Before I went into surgery I had some minor numbness in the heel of my left foot and in the back of my thigh. When I woke up from surgery, my entire left foot was numb (from the ankle down). It is still numb and there has not been any improvement at all since the surgery. The only change since the surgery is that now I have terrible pain in the bottom of my foot when I try to walk and severe cramping in my foot and calf. I know I am supposed to be walking a lot to help recover from my surgery, but at this point the only thing I feel in my foot is pain and every step is excruciating. Has anyone else experienced anything like this??
