Sciatica: Understanding Nerve Pain Down the Leg

What Sciatica Actually Is

Sciatica isn’t a diagnosis — it’s a description: pain radiating along the path of the sciatic nerve, from the lower back or buttock down the leg, sometimes with numbness, tingling, or weakness. The most common cause is irritation of a nerve root in the lower spine, often from a disc herniation or narrowing of the nerve’s exit canal.

True sciatica usually makes the leg the star of the show — leg symptoms equal to or worse than the back pain itself.

The Typical Course

Most episodes improve meaningfully over 6–12 weeks. Early on, the goal is to calm the nerve: finding positions and movements that reduce leg symptoms, managing inflammation, and staying as active as symptoms allow. As the leg settles, treatment shifts to rebuilding the back’s tolerance for load — and your confidence with it.

What About Surgery?

Surgery (most commonly a microdiscectomy) is reserved for progressive weakness, intractable pain that fails months of conservative care, or emergency presentations. For everyone else, high-quality trials show that patients who rehab and patients who have surgery end up in similar places at one year — without the operating room.

Recovery Timeline at a Glance

• Weeks 0–2: calm the nerve — positions of relief, gentle movement
• Weeks 2–6: nerve mobility work, progressive walking and loading
• Weeks 6–12: rebuild full strength and return to demanding activity

Quick Answers

Is sitting bad for sciatica? Sitting often aggravates it temporarily, but it isn’t damaging. Break it up, adjust positions, and keep moving within tolerance.

What sleeping position helps? Side-lying with a pillow between the knees, or back-lying with knees supported, reduces nerve tension for many people. Experiment — relief positions are individual.

How do I know it’s improving? Leg symptoms retreating toward the buttock/back (centralizing), longer walking tolerance, and easier mornings — even before pain intensity drops.

How RecoveryX Helps

Nerve pain is intimidating, and the internet makes it worse. A RecoveryX assessment maps your specific presentation, gives you a staged written plan, and keeps a physiotherapist within messaging reach for the “is this normal?” moments that define a nerve recovery.
