The most common symptom from sciatica is pain. Most people describe a deep, severe pain that starts low on one side of the back and then shoots down the buttock and the leg with certain movements.
Sciatica can also cause a hip pain. The pain is usually worse with both prolonged sitting and standing. Frequently, the pain is made worse by standing from a low sitting position, such as standing up after sitting on a toilet seat.
In most people, the pain is made worse by sneezing, coughing, laughing, or a hard bowel movement. Bending backward can also make the pain worse. You may also notice a weakness in your leg or foot, along with the pain. The weakness may become so bad you can't move your foot.
