Leg pain is not always caused by an actual problem in the leg or a related condition in the ankle or foot. Many types of leg pain stem from lower back conditions like a herniated disc, spinal stenosis or spondylolisthesis that irritate the nearby nerve root, with symptoms carried from the sciatic nerve down the back of the leg and even into the foot in some instances.
The term "sciatica" is used to describe symptoms of leg pain and possible numbness, tingling and weakness that is referred from the lower back along the sciatic nerve. With sciatica, the patient may feel no back pain but have severe leg pain.
