11 Nov Sciatica: How Long Does It Last, and When Should You Worry?

Say it started with a twinge in your lower back after a long drive home from a FIFO swing. A few days later there’s a burning, electric pain running through your buttock and down the back of your leg. Sitting is awful. You’ve been lying awake googling, and every result seems to say something different.

So here’s the honest answer first. For most people, sciatica does settle. It isn’t usually caused by anything dangerous, and the majority of people get better without surgery. It does tend to take longer than anyone would like, often weeks to a few months, and it can be frustrating. Below is what’s going on, a realistic timeline, the signs that mean you shouldn’t wait, and what you can do in the meantime.

What sciatica actually is

“Sciatica” isn’t a diagnosis on its own. It’s a description: pain that travels from the lower back or buttock down the leg, along the path of the sciatic nerve. It happens when one of the nerve roots in your lower back gets irritated or squeezed. The most common reason is a disc that’s bulged or herniated and is pressing on or inflaming the nerve. Less often, it’s narrowing around the nerve as the spine ages.

That’s why it can feel so strange. The problem is near your spine, but you feel it in your calf or foot. Burning, shooting, pins and needles and numbness are all common. Coughing or sneezing can make it zap. And your back might barely hurt at all.

So how long does sciatica last?

Everyone’s different, but here’s the general pattern. Many people notice things easing within the first few weeks. Most improve substantially over six to twelve weeks. A smaller group still has symptoms after several months, and some people have niggles for a year or more, often on and off.

Two things are worth knowing. First, pain usually improves before numbness or tingling does, so a bit of leftover pins and needles doesn’t mean it isn’t healing. Second, recovery is rarely a straight line. Good days and bad days are normal. Look at the trend over a couple of weeks, not a single morning.

healthdirect suggests seeing a doctor if you’ve been treated for four weeks and things haven’t improved. That’s a sensible checkpoint.

When to worry: get urgent help if you notice these

Most sciatica is uncomfortable but not dangerous. Some signs, though, mean the nerves need urgent medical attention. Go to an emergency department or call 000 if you have:

• New trouble passing urine, or loss of bladder or bowel control
• Numbness around your groin, genitals, bottom or inner thighs (the “saddle” area)
• Weakness in your leg or foot that’s getting worse, such as your foot slapping or catching when you walk
• Symptoms in both legs at once

See your GP promptly if back and leg pain comes with fever, unexplained weight loss, a history of cancer, or pain that’s severe at night no matter how you lie.

What helps while it settles

Keep moving, gently. Bed rest feels right but tends to slow recovery. Short, frequent walks are usually better than one long one. A slow lap of the block or a flat stretch of the Swan River path counts.

Break up sitting. Sitting is often the worst position. Get up every 20–30 minutes, even for a minute. If you’re driving long distances, plan stops.

Find your easing positions. Lying on your back with your calves up on a couch, or on your side with a pillow between your knees, often takes the edge off.

Watch how far it travels. If an activity makes the pain spread further down your leg, ease off it for now. If pain stays put or retreats towards your back, that’s generally a good sign.

Talk to your GP or pharmacist about pain relief if you can’t sleep or move. Getting some sleep matters.

Do I need an MRI?

Usually not straight away. Australia’s Low Back Pain Clinical Care Standard recommends scans only when they’d change what happens next. That might be when serious problems are suspected, nerve function is getting worse, or severe leg pain isn’t settling and an injection or surgery is being considered. Scans also show plenty of disc changes in people with no pain at all, which can make results more confusing than helpful. If you already have a scan, our post on surprising lower back pain facts explains why the report isn’t the whole story.

When it’s worth getting checked, and what we’d do

It’s worth booking in if the pain isn’t easing after a week or two, if it’s stopping you working or sleeping, or if you just want to know it’s safe to keep moving. At a first visit we’ll ask how it started and where it travels, and test your strength, reflexes and sensation. That tells us how the nerve is coping. If anything suggests you need a GP review or imaging, we’ll tell you.

From there, care may include advice on positions and activity, hands-on treatment where it’s suitable, nerve-friendly exercises and a gradual plan to rebuild strength through your back, hips and legs. Our physio team at Osborne Park, including Senior Physiotherapist Pádraig Hughes, and our chiropractors at Applecross and Osborne Park all see sciatica regularly. If your symptoms have dragged on for months, Pádraig is trained in Cognitive Functional Therapy, an approach developed at Curtin University here in Perth for persistent pain.

Sciatica FAQs

How long does sciatica usually last?

Many people improve within a few weeks, and most improve substantially within six to twelve weeks. Some people have symptoms for several months or longer. Numbness and tingling often take longer to settle than pain.

Should I rest or keep moving with sciatica?

Gentle movement is usually better than bed rest. Short, frequent walks and regular breaks from sitting tend to help. Ease off anything that makes the pain spread further down your leg.

Can I keep working with sciatica?

Many people can, sometimes with changes like more breaks from sitting, lighter duties or shorter shifts for a while. Staying at work in some form is generally encouraged where it’s possible.

When is sciatica an emergency?

Seek urgent medical care if you have loss of bladder or bowel control, numbness in the saddle area, worsening leg weakness or symptoms in both legs.

Should I see a physio or chiropractor for sciatica?

Both chiropractors and physiotherapists assess and manage sciatica. If you’re unsure, a free screening can help you decide, and we’ll tell you if you should see your GP instead.
