Sciatica is usually caused by pressure on the sciatic nerve from a herniated disc (also referred to as a ruptured disc, pinched nerve, slipped disk, etc.) in the lumbar spine.

Symptoms include:

Burning or tingling down the leg

Weakness, numbness or difficulty moving the leg or foot

A constant pain on one side of the rear

A shooting pain that makes it difficult to stand up

Low back pain may be present along with the leg pain, but usually the low back pain is less severe than the leg pain
