Symptoms:

Sciatica pain can vary widely. It may feel like a mild tingling, dull ache, or a burning sensation. In some cases, the pain is severe enough to make a person unable to move.

The pain most often occurs on one side. Some people have sharp pain in one part of the leg or hip and numbness in other parts. The pain or numbness may also be felt on the back of the calf or on the sole of the foot. The affected leg may feel weak.

The pain often starts slowly. Sciatica pain may get worse:

• After standing or sitting
• At night
• When sneezing, coughing, or laughing
• When bending backwards or walking more than a few yards, especially if caused by spinal stenosis

Signs and tests:

The health care provider will perform a physica exam. This may show:

• Weakness of knee bending or foot movement
• Difficulty bending the foot inward or down
• Abnormal or weak reflexes
• Pain when lifting the leg straight up off the examining table

Tests determine on the suspected causes. They are often not needed unless pain is severe or long lasting. They may include:

• Blood tests
• X-rays
• MRIs or other imaging tests
