Sciatica is one of the most common conditions I see in clinic — and one of the most misunderstood. Patients arrive having spent weeks resting, waiting for it to pass, only to find the pain has settled in. The first question almost everyone asks is the same: how long is this going to last?
The honest answer is that it depends — on the cause, the severity and what you do about it. But most cases of sciatica resolve significantly faster with the right treatment than they do with rest alone.
What Is Sciatica?
Sciatica isn't a diagnosis in itself — it's a description of symptoms. It refers to pain, tingling, numbness or weakness that travels along the sciatic nerve, typically from the lower back through the buttock and down the leg, sometimes reaching the foot.
The most common cause is irritation of one of the nerve roots in the lumbar spine — usually from a bulging or herniated disc, or from joint changes in the spine that narrow the space the nerve travels through. Understanding the cause matters because different causes respond differently to treatment.
How Long Does Sciatica Last?
The short answer: Most cases resolve within 4–12 weeks with appropriate physiotherapy. Without treatment, sciatica commonly persists for 6 months or longer — and in some cases becomes a recurring problem.
Recovery time varies considerably depending on several factors. Here's what typically happens at each stage:
Weeks 1–2 — Acute phase
Pain is often at its most intense. The nerve is sensitised and any movement that loads it — sitting, bending, sneezing — can be very uncomfortable. The priority at this stage is reducing nerve irritation, not stretching or exercising aggressively.
Weeks 2–6 — Settling phase
With the right treatment, leg pain typically begins to centralise — moving from the foot or calf back towards the buttock and lower back. This is a positive sign that the nerve is recovering. Gentle movement and specific exercises become more important at this stage.
Weeks 6–12 — Recovery phase
Most patients see significant improvement by week 6–8. Residual tingling or mild leg discomfort may linger even as pain resolves — this is normal. Strengthening the core and hip muscles during this phase reduces the risk of recurrence.
Beyond 12 weeks
Cases that haven't improved by 12 weeks with treatment may need further investigation — imaging to assess the disc or nerve, or in rare cases a specialist referral. The majority of people, however, are significantly better well before this point.
What Affects Recovery Time?
Not all sciatica is the same. These factors influence how quickly it resolves:
The underlying cause
Sciatica caused by a disc bulge — where the disc is pressing on a nerve root — often responds well and quickly to physiotherapy, particularly to specific directional exercises. Sciatica from spinal stenosis (narrowing of the spinal canal, more common in older adults) tends to be a slower recovery.
How long you've had it
Acute sciatica that started within the last few weeks generally responds faster than long-standing symptoms. If pain has been present for several months without proper treatment, the nervous system can become sensitised in a way that requires more time and a more careful approach to resolve.
What you do about it
This is the factor you can actually control. Complete bed rest slows recovery. Staying gently active — walking, avoiding aggravating positions, doing specific exercises — consistently produces better outcomes. Physiotherapy that identifies the direction of movement that reduces symptoms (McKenzie approach) can produce dramatic improvement even in the first session.
Your general health and fitness
Stronger core and hip muscles provide better support for the lumbar spine and take load off the discs and nerves. Patients who are already reasonably active tend to recover faster. This is also why rehabilitation exercises — not just pain relief — are so important.
Will Sciatica Go Away on Its Own?
Some cases do resolve without treatment. The body has a natural capacity to heal disc injuries over time — the disc material that is pressing on the nerve can reabsorb. However, this process can take many months, during which time you may be in significant pain and unable to work, exercise or sleep properly.
Physiotherapy consistently produces faster recovery than waiting. It also addresses the underlying reasons the disc injury occurred in the first place — weakness, stiffness or movement habits that, if left unchanged, make recurrence much more likely.
What Makes Sciatica Worse?
Understanding what aggravates your sciatica helps you manage it day-to-day while treatment progresses. Common aggravating factors include:
- Prolonged sitting — especially in a flexed or slouched position
- Bending forward — putting on shoes, loading the dishwasher, picking things up
- Sneezing and coughing — the sudden increase in spinal pressure
- Long car journeys — sustained sitting with vibration
- Complete rest — counterintuitively, bed rest worsens recovery for most people
Positions and activities that often help include walking (gentle, flat terrain), standing rather than sitting, lying down with knees slightly bent, and the specific directional exercises your physiotherapist prescribes.
When Are Warning Signs That Need Urgent Attention?
Seek urgent medical attention if your sciatica is accompanied by: loss of bladder or bowel control, numbness in the saddle area (inner thighs and genitals), weakness in both legs, or symptoms that developed after significant trauma. These can indicate cauda equina syndrome — a rare but serious condition requiring emergency treatment.
When Should I See a Physiotherapist?
If your sciatica has lasted more than two weeks without clear improvement, or if it's significantly affecting your sleep, work or daily activity, physiotherapy is recommended. There's no benefit to waiting — earlier treatment means faster recovery and a lower chance of the problem becoming chronic.
At the first appointment, a physiotherapist will assess the cause of your symptoms, identify which movements and positions improve or worsen your pain, and create a treatment plan specific to your presentation. Many patients notice meaningful improvement within two to three sessions.
