Sciatica is a term used to describe symptoms of lower back pain, numbness, or tingling that originate in the lower back and travel down the sciatic nerve. It is often due to a spinal disc herniation pressing on one of the lumbar or sacral nerve roots. Other common causes are spinal stenosis, degenerative disc diseases. Treatment options include physical therapy, pain medication, exercise, and in some cases, surgery.
