What Is Sciatica?

Understanding Sciatica?

Sciatica is a common condition that causes pain, tingling, or numbness that radiates along the sciatic nerve — the longest nerve in your body. This nerve runs from the lower back, through the hips and buttocks, and down the back of each leg.

Sciatica isn’t a condition on its own — it’s a symptom of an underlying problem that affects the lower spine or nearby structures.

Common Causes of Sciatica

Herniated or Bulging Disc

The most common cause of sciatica. When the soft centre of a spinal disc protrudes or leaks out, it can press on the nearby nerve roots that form the sciatic nerve — triggering pain and weakness in the leg.

Spinal Stenosis

This condition involves the narrowing of the spinal canal, putting pressure on the nerves, including the sciatic nerve. It’s more common in older adults.

Degenerative Disc Disease

As spinal discs age and wear down, they lose their cushioning ability. This can irritate the nerve roots and lead to sciatica symptoms.

Piriformis Syndrome

The piriformis muscle (deep in the buttock) can become tight or inflamed, pressing on the sciatic nerve. This causes sciatica-like pain, often without spinal involvement.

Spondylolisthesis

This occurs when one vertebra slips forward over another, potentially compressing the nerve roots and irritating the sciatic nerve.

Pregnancy

In some women, the growing uterus and postural changes during pregnancy can compress the sciatic nerve, leading to temporary symptoms.

 Rare but Serious Causes

In rare cases, sciatica may be caused by: Spinal tumours, Infections, Trauma or injury to the spine
