Sciatica vs. Disc Herniation vs Stenosis: What’s the Difference?
Back or leg pain can be confusing. Many people hear words like sciatica, disc herniation, stenosis and aren’t sure what they mean.
This guide breaks it down in a simple way so you can better understand your pain.
Why Do These Get Mixed Up?
These problems all involve the spine and nerves. They can cause similar symptoms like pain, numbness, or weakness.
But they are not the same thing.
Knowing the difference helps you get the right treatment.
What Is Sciatica?
Sciatica is a symptom, not a diagnosis.
It means pain that travels:
From the low back
Through the buttock
Down the leg
Sciatic pain often feels:
Sharp or burning
Like an electric shock
Sciatica happens when the sciatic nerve is irritated. Many spine problems can cause it.
What Is a Disc Herniation?
A disc herniation (aka bulging disc) happens when a spinal disc bulges or tears.
The disc can press on a nerve and cause pain.
Common signs include:
Back or neck pain
Pain down the arm or leg
Tingling or numbness
Muscle weakness
A disc herniation is a common cause of sciatica.
What Is Spinal Stenosis?
Spinal stenosis means the space inside the spine becomes too narrow.
This narrowing puts pressure on the nerves.
Stenosis often develops over time.
Common symptoms include:
Back or neck pain
Leg pain with walking or standing
Numbness or weakness
Relief when sitting or leaning forward
