Sciatica

Sciatica is pain, tingling, or numbness produced by an irritation of the nerve roots that lead to the sciatic nerve. 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.


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. But sciatica also can be a symptom of other conditions that affect the spine, such as narrowing of the spinal canal ,caused by arthritis, or nerve root compression .



Symptoms of sciatica include pain that begins in your back or buttock and moves down your leg and may move into your foot. Weakness, tingling, or numbness in the leg may also occur.

Sitting, standing for a long time, and movements that cause the spine to flex (such as knee-to-chest exercises) may make symptoms worse.
Walking, lying down, and movements that extend the spine (such as press-ups) may relieve symptoms.
