The sciatic nerve is your body’s longest nerve and one of the most important ones. It has a direct effect on your ability to control and feel your legs. When this nerve is irritated, you’ll experience sciatica. Sciatica is a sensation that can manifest itself as a moderate to severe pain in your back, buttocks, and legs. You may also feel weakness or numbness in these areas.
