Sciatica vs slipped disc is one of the most misunderstood pain questions.

They’re related but not the same thing.

What Is A Slipped Disc?

A slipped disc (disc herniation) happens when:

• A Disc Bulges Or Ruptures
  
  

• It Presses On Nearby Nerves
  
  

• Pain Starts In The Lower Back
  
  

Disc herniation symptoms depend on which nerve is affected.

What Is Sciatica Then?

Sciatica isn’t the disc problem itself.

It’s the resulting nerve pain when the sciatic nerve is irritated.

This is why:

Slipped Disc Symptoms vs Sciatica

Slipped disc symptoms often include:

• Localised Back Pain
  
  

• Pain With Bending Or Lifting
  
  

• Stiffness
  
  

Sciatica symptoms include:

• Pain Shooting Down The Leg
  
  

• Burning Or Tingling Sensations
  
  

• One-Sided Leg Pain

Why This Difference Matters

Treating the disc alone doesn’t always resolve sciatic nerve irritation.

In many cases, inflammation remains even after pressure eases, keeping pain active.

That’s why people can still hurt even when scans improve.
