What Causes Sciatica? Common Triggers and Risk Factors

Sciatica refers to pain that travels along the sciatic nerve, which runs from the lower back through the hips and down each leg. Many people in Beaverton search for relief when they experience sharp, shooting pain, numbness, or tingling that radiates below the knee. Understanding what causes sciatica is the first step toward effective treatment.

What Is Sciatica?

Sciatica is not a condition by itself. It is a symptom of irritation or compression of the sciatic nerve. The pain can range from mild discomfort to severe, burning or electric-like sensations. Some individuals also experience muscle weakness or difficulty standing for long periods.

Common Causes of Sciatica

Several underlying conditions can trigger sciatic nerve pain.

1. Herniated or Bulging Disc

One of the most common causes is a lumbar disc pressing on the nerve root. This often happens due to age-related wear and tear or sudden strain.

2. Spinal Stenosis

Narrowing of the spinal canal can compress nerves in the lower back, leading to leg pain and tingling.

3. Piriformis Syndrome

The piriformis muscle, located deep in the hip, can irritate the sciatic nerve if it becomes tight or inflamed.

4. Degenerative Disc Changes

As discs naturally lose hydration over time, the surrounding structures may place pressure on nearby nerves.

5. Injury or Trauma

Falls, lifting injuries, or repetitive strain can contribute to sciatic nerve irritation.

How Long Does Sciatica Last?
