How Long Does Sciatica Last? A Physio's Honest Timeline (and How to Speed It Up)

The lightning bolt down your leg

Here's a typical story, with the details changed. Daniel, 39, runs a busy warehouse in Birmingham. One Monday he bent down to pick up a dropped box, felt a twinge in his lower back and thought nothing of it. By Wednesday a hot, burning pain was shooting from his bum down the back of his left leg. Sitting in the car was agony. Sleep was patchy at best.

That night he typed the same question thousands of people search every month: how long does sciatica last? He wanted a number, a date in the diary when he could get back to normal. If that's you right now, this guide is for you.

The short answer. According to the NHS, sciatica usually gets better in a few weeks to a few months, but it can last longer. That's the honest headline. But "a few weeks to a few months" is a big range, so let's break down what's happening, what the usual timeline looks like and what you can do to land at the shorter end of it.

What's actually going on in there?

Your sciatic nerve is the longest nerve in your body. It starts in your lower back, runs through your buttock and travels down the back of each leg to your feet.

Sciatica isn't a diagnosis on its own. It's a word for the pain, tingling or numbness you get when that nerve is irritated or pressed on. The most common cause is a bulging or "slipped" disc in the lower back. Other causes include narrowing of the spinal canal and tight muscles around the hip.

Muscle pain tends to ache. Nerve pain is different. People describe it as burning, electric, shooting or like pins and needles. It can be worse when you sit, cough, sneeze or bend forward. That's why sciatica can feel so scary, even when the cause is something that usually settles by itself. The timeline depends on how quickly that irritated nerve calms down.

The sciatica timeline: week by week

Every back is different, and nobody can promise an exact date. But physios often see a pattern like this:

Stage	Roughly when	What it often feels like
Flare-up	First 1–2 weeks	Sharp, shooting pain; sitting and sleeping are hard
Settling	Weeks 2–6	Pain starts to ease; good and bad days; more movement
Recovering	Weeks 6–12	Pain is less frequent; strength and confidence return
Longer-lasting	Beyond 3 months	Some people still have symptoms and need more support

UK Physio Tip: For many people the worst is over within the first few weeks, and sciatica usually improves without surgery. If your pain hasn't improved after a few weeks of home treatment, is getting worse, or is stopping you doing normal things, the NHS advises seeing a GP. A physio can help too.

Five things that change how long sciatica lasts

• How much you move. This is the big one. The NHS advises carrying on with normal activities as much as possible and not sitting or lying down for long periods. Bed rest feels tempting, but it usually makes stiffness and pain worse.
• The cause. A small disc bulge often settles faster than nerve pressure caused by narrowing in the spine. Your physio or GP can help you understand what's likely driving your pain.
• Your job and daily routine. Long hours driving, sitting at a desk or heavy lifting can keep the nerve irritated. Staying active and changing between sitting and standing every 30 minutes or so helps.
• Sleep and stress. Poor sleep and high stress can make pain feel worse and last longer. Looking after both is part of recovery, not a luxury.
• Getting the right help early. People who get clear advice and a simple exercise plan early often feel more in control, and that can make a real difference to how long sciatica lasts for them.

Myth vs fact: what people get wrong about sciatica

Myth	Fact
"If it hurts this much, I must have done serious damage"	Not usually. Nerve pain can feel dramatic, but the level of pain doesn't always match the level of damage. An irritated nerve sends strong warning signals even when the cause often settles with time.
"Sciatica always ends in surgery"	Most people never need an operation. Surgery is usually only considered when symptoms are severe, aren't improving after other treatment, or red flags appear.
"Older people take forever to recover"	Age can play a part, but it isn't the whole story. How active you stay, your general health and getting good advice early all matter just as much.
"Bed rest is the best cure"	Staying in bed usually makes things worse. Gentle movement helps the nerve settle and stops your back getting stiff.

Your speed-up plan: what actually helps

Keep moving, gently. Short, regular walks are one of the best things you can do. Start with five or ten minutes and build up. Change position often.

Try simple exercises. Gentle exercises can ease pressure on the nerve and keep your back moving. Stop if pain spreads further down your leg.

• Knee-to-chest stretch: lie on your back and gently hug one knee towards your chest
• Pelvic tilts: lie with knees bent and gently flatten your lower back into the floor
• Glute stretch: lie on your back, cross one ankle over the other knee and gently pull
• Cat–cow: on hands and knees, gently arch and round your back
• The Chartered Society of Physiotherapy has video exercises for back pain you can follow. For more ideas, read our post on five exercises to relieve lower back pain at home.
• Use heat and smart positions. Heat packs on the painful area can help muscles relax. At night, try lying on your side with a pillow between your knees, or on your back with a pillow under your knees.
• Ask about pain relief. Speak to a pharmacist or GP about painkillers that are safe for you. Pain relief can make it easier to move, and moving is what helps you recover.

How Daniel got back on his feet

Daniel didn't want to sit in a car to get to a clinic, so he booked a FlexAura physio to visit him at home. The physio asked about his job, checked how he moved, tested the nerves in his legs and ruled out red flags. They explained what was likely happening, showed him three gentle exercises and helped him find a sleeping position that eased the leg pain. Then they left him a written plan.

Over the next weeks he walked every day, did his exercises morning and evening, and took short breaks from his desk. He had a few bad days, which his physio had warned him about. By week four the leg pain was much less frequent. By week eight he was back to full shifts.

Everyone's recovery is different, and no physio can promise a set result. But knowing what to expect took away much of the fear. The question of how long sciatica lasts stopped being scary once he had a plan.

Why physio at home makes sense for sciatica

When sitting hurts, a car ride to a clinic can undo a lot of good. With sciatica physiotherapy at home, your physio comes to you, sees how you sit, sleep and move in your own space, and builds a plan around it.

• Sciatica in both legs
• Weakness or numbness in both legs that's severe or getting worse
• Numbness around or under your genitals, or around your bottom
• Difficulty peeing, or loss of bladder control
• Loss of bowel control
• These are rare, but don't wait. Physiotherapy comes after serious problems are ruled out.
