Definition: Sciatica is a common cause of low back pain and leg pain. It is usually caused by pressure on the sciatic nerve from a herniated disc. Sciatica occurs most frequently in people 30 to 50 years of age and can be a debilitating disorder in some people.
Sciatica normally only affects one side of the lower extremities, and the pain often radiates from the lower back all the way down the back of the thigh and the leg. Depending on where the sciatic nerve is affected, the pain may also radiate to the foot or toes.[
Also Known As: lumbar radiculopathy
