Part 6 · Myth 29

Sciatica means a pinched nerve that needs surgery

Partial Truth
From the Clinic

Her neighbour had surgery for sciatica six weeks ago and swore it was the only thing that worked. My patient had been in pain for five weeks and was ready to push for an operation. Five weeks into a disc herniation that was still within its natural recovery window — she needed time and a proper plan.

What Patients Say

I've been told I have sciatica. My neighbour had sciatica and had surgery — he said it was the only thing that worked. I've had this for six weeks. Should I be pushing for surgery too?

Where Did This Come From?

"Sciatica" is a term that gets used very loosely, which creates enormous confusion. To a doctor, sciatica (more precisely called lumbar radiculopathy) means radiating leg pain caused by nerve root irritation or compression — usually from a disc herniation or bony narrowing in the lumbar spine. To patients, and sometimes to clinicians, it's used for almost any pain that travels into the buttock or leg.

The loose use of the term means that people compare experiences with "sciatica" who may have completely different underlying problems — from a significant disc herniation compressing the L5 nerve root to simple piriformis muscle tightness. This makes neighbour-to-neighbour advice essentially meaningless, even with good intentions.

What the Science Actually Says

True lumbar radiculopathy — nerve root compression causing radiating leg pain, with or without neurological deficits — has a natural history that is generally favourable for most patients. Studies consistently show that 60–80% of patients with lumbar radiculopathy improve significantly with conservative management within 6–12 weeks.

Surgery for disc-related sciatica (microdiscectomy) provides faster pain relief but doesn't change 1–2 year outcomes compared to conservative management in most studies. Surgery is indicated: for patients with severe, refractory pain not responding to adequate conservative treatment; for those with progressive neurological deficit; and for cauda equina syndrome (emergency).

Six weeks is often not enough time to determine that conservative management has failed. The guidelines for most disc-related radiculopathy suggest an adequate conservative trial of 8–12 weeks before surgical consideration, except where urgent neurological indication exists.

Your neighbour's situation, anatomy, nerve, and timeline may be completely different from yours. Don't copy the treatment plan — understand your own condition.

The Verdict

Surgery is a legitimate option for sciatica that isn't responding to conservative management. But at six weeks, most patients are still within the window where conservative management should be given a proper chance. Surgery's role is time-defined and indication-specific.

Take-Home MessageDon't rush to surgery at six weeks based on your neighbour's experience. But also don't suffer indefinitely assuming you have to wait. Engage actively with conservative treatment — appropriate medication, physiotherapy, activity modification. Set a timeline with your doctor: if not significantly improved by X weeks, then discuss the surgical option. Have a plan, not just hope.

What To Do Instead

Yellow Flags — Worth Monitoring

  • Leg pain that is not improving at all after 8–10 weeks despite appropriate management — time to discuss options including surgical
  • Significant sleep disturbance from pain — this needs addressing (medication review, possible escalation of treatment) as chronic sleep deprivation worsens pain

Red Flags — Get Checked Immediately

  • Progressive leg weakness — worsening over days — urgent surgical review
  • Bladder or bowel dysfunction with back and leg pain — cauda equina syndrome, this is a surgical emergency
  • Saddle area numbness (inner thighs, perineum) — also cauda equina territory, emergency
