Sciatica and Herniated Discs: Causes, Symptoms, and Treatment

Sciatica and herniated discs are two of the most common reasons for lower back pain and leg pain. Many people experience sharp, shooting pain that starts in the lower back and radiates down the leg—but few realize that a herniated disc is often the root cause of sciatica. we’ll explain the connection between herniated discs and sciatica, explore their symptoms, and discuss effective treatment options.

Your spine is made up of small bones called vertebrae, separated by spinal discs. These discs act as cushions, absorbing shock and allowing your spine to move smoothly. A herniated disc, also known as a slipped or ruptured disc, happens when the soft, jelly-like center of the disc pushes through a crack in the outer layer. This can press on nearby nerves—most commonly the sciatic nerve.

What Is Sciatica?

Sciatica is not a disease but a set of symptoms caused by compression or irritation of the sciatic nerve, which runs from your lower back down through your hips, buttocks, and legs.

Common Causes of Sciatica:

• Herniated disc (most common)

• Bone spurs on the spine

• Spinal stenosis (narrowing of the spinal canal)

• Degenerative disc disease

• Injury or trauma to the lower back
