Why Sciatica Happens

That sharp, shooting pain running down your leg often comes from a nerve that isn’t gliding properly.

Your nerves are designed to slide and glide through surrounding tissues as you move. But if a muscle, joint, or bit of connective tissue becomes tight or irritated, the nerve can get impinged.

Instead of gliding, it gets stretched — and nerves really don’t like being stretched. That’s when pain and irritation begin.

What Is Nerve Flossing?

Nerve flossing is a technique used to restore that smooth gliding motion.

Think of it like flossing your teeth — you gently pull from one end while giving slack on the other. Repeating that motion through a narrow or restricted area can:

• Free up the tissue around the nerve

• Help the nerve move more easily

• Encourage healing and mobility

• Reduce pain and sciatica symptoms

The most common restriction is near the spine where the nerve exits the canal. Flossing helps clear that space so the nerve can move freely again.

⚠️ A Word of Caution

Nerve flossing works well for many people — but not everyone.

In some cases, it can increase irritation and make symptoms worse.
If that happens to you, stop. Don’t push through the pain.

How to Do the Sciatic Nerve Floss

Here’s the basic step-by-step technique:

Step 1:

• Look up toward the ceiling

• Straighten your leg

• Point your toes up toward the ceiling

Step 2:

• Look down toward the floor

• Bend your knee

• Point your toes down toward the floor

Move slowly and deliberately — about 5 seconds in each direction.

What If It Hurts?

If you feel discomfort:

• Make the movement smaller

  • Don’t look up or down as far

  • Don’t point your toes as high

• Remove the neck movement

  • Just do the leg portion (a gentler version)

Even the modified version can help without irritating the nerve.

Guidelines for Reps and Progression

• Begin with 10 slow reps per leg

• If it feels okay, the next day try doing 2 rounds at separate times

• If tolerated, increase to 3 rounds per day

• You can eventually do it every few hours — but only if it’s helping

• If irritation increases, stop
