What is Sciatica?
Sciatica is pain radiating from the lumbar-sacral spine and buttock through the back of the thigh and lower leg to the foot. The pain occurs in the area innervated by the sciatic nerve and may sometimes be accompanied by neurological symptoms, such as sensory disturbances or muscle weakness. Symptoms result from compression or irritation of the sciatic nerve or the nerve roots that connect to form the nerve. The pain may affect one or both legs and is usually preceded by lower back pain.
