Patients suffering from Sciatica experience pain, tingling, numbness, or weakness caused by an irritated or pinched sciatic nerve or the nerve roots that form it. Usually, it starts in the lower back or buttock and travels down one leg.

You bend to pick something up and suddenly there is a sharp pain in your lower back. A few days later, it is running down your leg like an electric current. Scary, right?

Some people get only a mild tingle. Others have severe pain or even a numb foot. Normal back pain stays in the back, but nerve pain travels. If it keeps coming back or is getting worse, it is time to meet a sciatica specialist. A neurologist for sciatica finds what is pressing on the nerve, instead of just covering the pain with tablets.

What Is Sciatica?

Sciatica is not a disease on its own. It is a pattern of symptoms that tells you something is irritating a nerve.

The sciatic nerve is the longest nerve in your body. It starts from nerve roots located in your lower spine, passes through the buttock and runs down to the back of your leg. If one root gets compressed then you can feel it anywhere in that path. You can have a back problem but it’ll show up as pain in your calf or foot.

Doctors call this lumbar radiculopathy. In simple words, a nerve root in the lower back is pinched or irritated.

Is Sciatica The Same As Lower Back Pain?

No, but they both can happen at the same time.

Particulars	Common Lower Back Pain	Sciatica
Where?	Mostly the lower back	Back or buttock, going down the leg
Feels like	Dull, achy, stiff	Sharp, burning, shooting
Numbness or tingling	Not common	Quite common
Usual cause	Muscle or joint strain	Nerve irritation or pressure

What Are The Symptoms of Sciatica?

It often feels sharp, burning or like an electric shock, running from the lower back or buttock down one leg. Common sciatica symptoms include:

• Sharp, burning or shooting pain in one leg
• Numbness in the leg or foot
• Tingling or pins and needles
• A weak leg or foot
• Pain that gets worse when you cough, sneeze or sit for long
• Trouble standing or walking, in serious cases

Which Symptoms Mean A Nerve Compression?

Numbness, tingling and weakness are the ones you should not ignore. They often mean a nerve root is being pressed. Pain alone can come from muscles or hips too, so not every leg pain is sciatica.

What Causes Sciatica?

There is no single reason that can cause this problem, but here are the most common causes.

Slipped Disc or Herniated Disc

Think of the bones in your back as a pile of building blocks. Between each block, there is a soft, squishy cushion. This cushion stops the bones from rubbing together when you move.

Sometimes, this squishy cushion gets squished out of place, just like tomato squeezing out of a sandwich. If it touches a nearby nerve, it can cause pain, tingling, or numbness down your leg.

So, can a slipped disc cause sciatica? Yes, and it is one of the most common reasons.

Lumbar Spinal Stenosis

Your nerves travel through a small tunnel inside the spine. Over time, this tunnel can become narrow and the nerves get less room than they need.

You may notice the pain more when you stand or walk for a while. Sitting down or leaning forward often gives some relief. That is a classic sign of this type of cause.

Age-Related Wear and Tear

Our spine gets old along with us. The discs slowly lose their softness and the joints between the bones wear down. This can leave less space for the nerves.

It is more common after the age of 40 or 50. The good news is that many people have this wear and tear and never feel any pain. So a change on your scan does not always mean trouble.

Other Possible Causes

• Spondylolisthesis, in it one bone in the spine slips forward over the bone below it
• Other spine or nerve problems that can feel just like sciatica
• Rarer causes that need a doctor to find and rule out

If your leg pain does not fit any of these, do not try to guess the reason yourself. A proper check will tell you what is really going on.

Who Is More Likely To Get Sciatica?

Some things just raise your chances. They do not decide it. Like:

• Getting older
• Long hours of sitting or desk work
• Lifting or bending the wrong way
• Being overweight
• Earlier back problems

When Should You See a Sciatica Specialist?

See one if the pain keeps returning or getting worse or if you have numbness or weakness in the leg. A neurologist checks how well your nerves work which helps find the real cause.

Book A Consultation if pain is severe, sleep or walking is disturbed, or home care and rest have not helped.

When Is Sciatica An Emergency?

Please do not wait and watch it lead to an emergency situation. Get medical help as soon as possible if you see any of these sciatica symptoms.

• New trouble controlling urine or stool
• Numbness around the groin or inner thighs
• Sudden weakness in the legs, or weakness getting worse fast
• Severe back pain with fever

How Is Sciatica Diagnosed?

It starts with a simple consultation. The doctor asks when the pain began, where it goes and what makes it worse. Then comes a nerve check.

Neurological Examination

The doctor checks muscle strength, reflexes, sensation, how you walk and exactly where the pain and numbness are.

Imaging Tests

An MRI of the lower spine can help in some cases as it shows discs and nerve spaces clearly. But a scan must always be read along with your symptoms. Many people have MRI changes and feel no pain at all.

EMG and NCV Tests for Nerve Problems

Not everyone needs these tests or an MRI. Your doctor will suggest them only when your symptoms call for it.

Tests	What It Checks	Why It May Help
EMG Test	Electrical activity in your muscles	Shows if a muscle is not getting proper signals
NCV Test	How well signals travel along nerves	Helps find a squeezed nerve

Sciatica Treatment Options

What is the best treatment for sciatica? There is no single best treatment for everyone. The right plan depends on the cause, how severe it is, how long you have had it and what the nerve examination shows.

Conservative Treatment

Most people start here:

• Changing daily activity for a short time, without staying in bed for days
• Physiotherapy and guided exercises
• Pain-relief medicines, only as your doctor advises
• Better sitting posture
• Slowly returning to your normal routine

Treatment For The Underlying Cause

A slipped disc, spinal stenosis or another spine problem may each need a different approach. That is why finding the cause matters so much.

When Is Surgery Considered?

Some people need more than basic care. This may be true if the pain is severe and does not settle, if there is clear weakness, or if a specific spine problem is found. Surgery is not needed for most people and every case is different.

Can Sciatica Go Away on Its Own?

Sometimes, yes. Many episodes settle with time and simple care. But recovery differs from person to person. If the pain stays, keeps returning or gets worse, please do not ignore it.

Frequently Asked Questions

Can a slipped disc cause sciatica?

Yes. A slipped disc can press on a nearby nerve root and send pain or numbness in the leg.

How long does sciatica last?

It varies. Some people feel better in a few weeks, others take longer. If symptoms last long, get them checked.

Can sciatica cause numbness in the leg?

Yes. A compressed nerve cannot carry feeling properly, so you may feel numbness or tingling in the leg or foot.

Are EMG and NCV tests needed for sciatica?

Only sometimes. Doctors order them when your symptoms and examination need them.

When is sciatica serious?

When leg weakness is increasing, the groin area is numb, or you cannot control urine or stool. Get urgent care.
