Sciatica: Exercises That Help, Exercises to Avoid, and When to See a Doctor

What Is Sciatica?

Sciatica is pain that radiates along the sciatic nerve—from your lower back, through your hip and buttock, down the back of your leg. It can feel like an electric shock, burning sensation, or deep ache.

The sciatic nerve is the longest and thickest nerve in your body. When it's irritated, you know it.

What Causes Sciatica?

Most Common: Disc Problems

Herniated disc:

The disc's inner gel pushes through its outer layer and presses on the nerve root. This is the classic cause.

Degenerative disc disease:

Discs lose height and may bulge, narrowing the space where nerves exit.

Also Common

Spinal stenosis:

The spinal canal narrows, putting pressure on nerves. More common over 50.

Piriformis syndrome:

The piriformis muscle in your buttock spasms and compresses the sciatic nerve.

Spondylolisthesis:

One vertebra slips forward over another, pinching nerves.

Less Common

Red Flags: See a Doctor Now

Go to urgent care or emergency if you have:

These could indicate cauda equina syndrome—a medical emergency.

Exercises That Help

The goal: reduce nerve irritation and improve movement tolerance. What helps depends on your specific cause.

If Extension Feels Better (Most Disc Problems)

Prone prop:

Press-up (McKenzie extension):

Why it works: Extension can help "centralize" the pain (move it from leg toward back) by shifting disc material away from the nerve.

If Flexion Feels Better (Stenosis, Some Disc Cases)

Knee-to-chest:

Prayer stretch:

For Piriformis Syndrome

Figure-4 stretch:

Piriformis stretch seated:

Core Stability (Everyone)

Bird-dog:

Dead bug:

Modified plank:

Walking

Often the best exercise for sciatica. It's gentle, promotes circulation, and avoids sustained positions. Walk within your pain tolerance, even if that's just a few minutes initially.

Exercises to Avoid (Initially)

Heavy Lifting

Especially deadlifts, rows, and anything loading the spine. Wait until symptoms improve.

High-Impact Activities

Running, jumping, plyometrics—too much jarring.

Prolonged Sitting

Not exercise, but a common aggravator. Get up every 20-30 minutes.

Forward Bending Under Load

Picking things up with rounded back is the classic disc-herniation mechanism.

Stretches That Increase Leg Pain

If stretching makes the pain shoot further down your leg (peripheralization), stop. That's making it worse.

The Centralization Principle

This is key to understanding what helps your specific sciatica.

Centralization: Pain moves from leg toward back/buttock. This is GOOD—it means the nerve is being decompressed.

Peripheralization: Pain moves from back down into leg. This is BAD—something's making the nerve more irritated.

Find movements that centralize your pain and do more of them. Avoid movements that peripheralize.

Positions That Help

Lying Down

Often the most comfortable. Lie on back with knees supported by pillows, or on side with pillow between knees.

Standing vs Sitting

Most disc-related sciatica is worse sitting, better standing or walking. If you have stenosis, opposite may be true.

The 90-90 Position

Lie on back, calves resting on chair seat (knees and hips both at 90°). Takes pressure off discs.

How Long Does Sciatica Last?

Typical Timeline

Factors That Affect Recovery

When to Consider Surgery

Surgery is rarely the first option. Consider it if:

Common procedures: microdiscectomy, laminectomy.

Medications

For short-term relief (discuss with doctor):

Avoid relying on medication alone—exercise is essential.

Prevention

Protect Your Back

Build Core Strength

Strong core = protected spine. Make it a lifelong habit.

Stay Active

Regular movement keeps discs healthy. They don't have direct blood supply—they rely on movement to receive nutrients.

Don't Ignore Early Symptoms

Address low back pain before it becomes sciatica.

Sciatica is scary when it first hits, but most cases resolve with time and the right exercises. Find what centralizes your symptoms, stay active within your limits, and give it time. If you're not improving after 6-8 weeks, or if symptoms are severe, get professional evaluation.
