If so, you may be experiencing sciatica. Sciatica means irritation of the sciatic nerve, the largest nerve in the body, that runs from the lower back down the back of the leg to the knee where it splits into two nerves that run down to the foot. Irritation of the sciatic nerve results in pain radiating down the back of one leg, often accompanied by numbness, tingling, and back pain. People frequently have questions about what sciatica is, why it occurs, and how to find relief from the intense pain it can cause. The most important thing to know is that sciatica is a symptom rather than a condition and the cause of the nerve irritation is usually in the lumbar spine or the buttock.
