Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the lower back and runs down the back of each leg. This nerve controls the muscles of the back of the knee and lower leg. It also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot.
The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back. It goes down through the buttock, then its branches extend down the back of the leg to the ankle and foot. What causes sciatica? The most common cause of sciatica is a bulging or ruptured disc (herniated disc) in the spine pressing against the nerve roots that lead to the sciatic nerve.
