Herniated Disc vs. Sciatica: What’s the Difference?
herniated disc and sciatica
Back pain is one of the most common health complaints worldwide. Two terms often heard in this context are herniated disc and sciatica. While they’re closely related, they’re not the same. Understanding the difference can help you seek the right treatment and avoid unnecessary discomfort.
What Is a Herniated Disc?
Your spine is made up of bones called vertebrae, and between each vertebra is a soft cushion called a disc. These discs act like shock absorbers, helping you bend and twist comfortably.
A herniated disc (also called a slipped or ruptured disc) happens when the soft inner gel of the disc pushes out through a tear in the outer layer. This bulge can press on nearby nerves and cause pain.
Common Symptoms:
- Pain in the neck or lower back
- Tingling or numbness in arms or legs
- Muscle weakness
- Pain that worsens with movement

What Is Sciatica?
Sciatica is not a condition—it’s a symptom. It refers to pain that travels along the sciatic nerve, which runs from your lower back down each leg. Most often, sciatica is caused by a herniated disc pressing on the sciatic nerve.
Sciatica Symptoms:
- Sharp, shooting pain down one leg
- Burning or tingling sensations
- Pain worsens when sitting or standing
- Muscle weakness in the affected leg
How Are They Connected?
A herniated disc is one of the most common causes of sciatica. When the disc bulges and presses on the sciatic nerve, it triggers the radiating pain we associate with sciatica. So while they’re different, they’re often linked.

Graph: Pain Progression
This graph shows how sciatica pain often starts suddenly and radiates, while herniated disc pain may begin as localized discomfort and build gradually.
