Sciatica is a distracting pain that begins in the lower back and extends down one or both legs. It typically worsens with periods of sitting or standing.
The discs between the spinal bones of the lower back are often involved.
Trauma can cause one or more discs to bulge. This crowds nearby nerves, causing irritation and inflammation. Coughing, sneezing or other kinds of movement can be painful. If neglected, the nerve irritation extends down one or both legs along the sciatic nerves. The pain appears in the leg, but the culprit is often the lower back!
