Sciatica: Why It's Not What Most People Think (And What Actually Helps)

Sciatica Is a Symptom, Not a Condition

Pain, numbness, or tingling down the leg — that's sciatica. But sciatica is not a diagnosis. It's a description of where you feel the irritation.

What's causing that irritation is the question most treatments never adequately answer. And that's why so many people stay stuck.

The Four Possible Sources (And Why They Matter)

Sciatica can originate from four different structural problems — and each requires a different approach:

1. Lumbar Disc Herniation
The disc bulges and presses on the nerve root. Specific positions (usually flexion) make it worse. Requires extension-based movement strategies and core stability work.

2. Piriformis Syndrome
The piriformis muscle in the glute compresses the sciatic nerve where it passes underneath (or through) the muscle. Feels similar to disc herniation but responds to completely different treatment.

3. Sacroiliac Joint Dysfunction
The SI joint becomes hypermobile or restricted, irritating nearby nerve structures. Often mimics disc pain but originates at the pelvis.

4. Spinal Stenosis
Narrowing of the spinal canal compresses nerve roots. More common in older adults. Extension typically makes it worse (opposite of disc herniation).

Treating piriformis syndrome like a disc problem — or vice versa — will not work. This is why generic sciatica exercises found online help some people and make others worse.

5 Things That Make Sciatica Worse

Complete bed rest — weakens supporting structures and creates fear-avoidance, making recovery slower.

Aggressive stretching during a flare — pulling on an already irritated nerve can increase inflammation and pain.

Heavy lower body exercise without addressing the cause — loading a compromised structure accelerates damage.

Prolonged sitting — increases disc pressure and compresses the piriformis against the sciatic nerve.

Ignoring the pelvis — pelvic imbalance is a primary driver of sciatic nerve irritation regardless of the source.

What the Research Actually Shows

The research is clear: people with sciatica who receive a proper structural assessment and source-specific treatment recover significantly faster than those who receive generic treatment.

The problem is time. Most appointments are too short for thorough assessment. You get a diagnosis that sounds specific ("L4-L5 herniation") but treatment that's generic ("core exercises and stretching").

The Right Approach

1. Identify the actual source — which structure is irritating the nerve?
2. Reduce load on that specific structure
3. Restore movement in a way that doesn't aggravate the nerve
4. Correct the structural imbalance that created the problem

If you've been dealing with sciatica for more than a few weeks, getting a proper structural assessment is the single most important step you can take.
