Sciatica vs arthritis is a common confusion because both can cause back, hip and leg pain.

But they are not the same condition and behave very differently.

How Sciatica Pain Feels

Sciatica pain usually:

• Travels From The Lower Back Into The Leg
  
  

• Follows A Clear Nerve Path
  
  

• Feels Sharp, Burning Or Electric
  
  

• Affects One Side More Than Both
  
  

This happens because the sciatic nerve is irritated.

How Arthritis Pain Feels

Arthritis symptoms similar to sciatica can include stiffness and aching, but:

• Pain Stays Around The Joint
  
  

• It Feels Dull Or Stiff, Not Shooting
  
  

• Both Sides Are Often Affected
  
  

• Movement Loosens It Over Time
  
  

Arthritis is a joint issue, not a nerve issue.

Key Differences Between Sciatica And Arthritis

The difference between sciatica and arthritis comes down to:

• Nerve Pain vs Joint Pain
  
  

• Radiating Pain vs Localised Pain
  
  

• Sharp Pain vs Aching Stiffness
  
  

If pain shoots down the leg, sciatica is far more likely.

Can You Have Both?

Yes.

Arthritis can narrow joint spaces and contribute to sciatica, but it isn’t the same thing.

Understanding which one is driving your pain matters for choosing the right fix.
