If you have constant tingling in your leg or feel numb most of the time, you’re not imagining it.

Many people with sciatica experience persistent numbness or tingling that doesn’t switch off, even when pain changes or eases.

This usually means the nerve hasn’t calmed down.

Why Numbness Can Be Constant With Sciatica

Sciatica affects how nerves send signals.

When a nerve stays irritated:

• Normal sensation gets disrupted
  
  

• Signals misfire or weaken
  
  

• Numbness and tingling replace pain
  
  

That’s why people report:

• Numbness all the time
  
  

• Why foot always tingles
  
  

• Pins-and-needles that don’t go away
  
  

It’s not random. It’s a nerve response.

Why Sciatica Can Leave You Numb for Days

When inflammation stays active around the sciatic nerve, sensation may not return quickly.

This can cause:

• Sciatica numb for days
  
  

• Reduced feeling in the foot or calf
  
  

• Tingling that persists even at rest
  
  

This doesn’t mean the nerve is dead.

It means it’s still irritated.

Why the Nerve Isn’t Calming Down

People often ask why the nerve won’t settle.

In most cases, the nerve is not calming down because:

• Inflammation remains trapped
  
  

• Pressure has eased but irritation hasn’t
  
  

• Healing hasn’t fully completed
  
  

Until that irritation reduces, sensation stays abnormal.

This is when people understand why sciatica keeps coming back after temporary relief.

What To Do About Persistent Numbness

When numbness or tingling becomes constant, the focus shouldn’t be just symptom control.

It’s understanding why the nerve hasn’t stabilised and what’s keeping it irritated beneath the surface.

Once that’s clear, sensation often improves.
