This low back condition is an irritation or compression of one or more nerve roots in the lumbar spine. Because these nerves travel to the hips, buttocks, legs and feet, an injury in the lumbar spine can cause symptoms in these areas. Sciatica may result from a variety of problems with the bones and tissues of the lumbar spinal column. This condition is often the result of a herniated / budging disc, degenerative disc disease. Pain can be felt in many ways, depending on the location of the affected nerve root.
