I had back surgery in 2004 due to a herniated disk in my lower back. The disk was pressing on the nerve that controls my left calf. I had no pain, or other usual back symptoms, but I lost all strength in the left calf and could not run correctly. When I talked to my surgeon, he said he would not necessarily advise a non-athlete to have the surgery, but if I wanted to continue running, I had no choice. He was particularly concerned as weakness and numbness are signs that the nerves are being damaged, whereas pain is a sign the nerves are being irritated.
Since my back surgery, I have been very aware of my back. I work at a computer all day, and have a desk that allows me to stand. I am very careful about lifting anything. When I run, I am particularly aware of steep down hills - if the foot lands with the leg straight, this will put immense stress on the back. Of recent I have established a routine for strengthening my core, but I have not always been so diligent.
Below are some images I found useful that show what part of the body has sensation from nerves originating in particular parts of the spine.
