# What sciatica feels like: the pain, where it travels and the signs that need a doctor

It can start as a dull ache in your buttock, then one day shoot down your leg like a jolt. Sciatica has a recognizable feel and a recognizable path. Knowing both helps you tell it from a pulled muscle or a sore hip.

General information, not medical advice.

**The short answer:** sciatica usually feels like a sharp, burning or electric pain that runs from your buttock down the back of one leg, often into the foot and toes. Many people also feel tingling, pins and needles, numbness or weakness. It’s often worse when you move, sneeze or cough. The leg usually hurts more than your back.

Sciatica isn’t a diagnosis on its own. The American Academy of Orthopaedic Surgeons (AAOS) calls it a broad term for nerve pain. The cause is whatever is pressing on the nerve, most often a slipped disc, the NHS says.

## What does sciatica feel like?

Sciatica feels like nerve pain: sharp, burning or electric, often with tingling or numbness, running down one leg. The words people use vary a lot, and so does the strength:

- **Burning or electric shock.** Cleveland Clinic describes a burning or electric shock feeling that shoots down one leg.
- **A bad leg cramp.** The AAOS says it may feel like a bad leg cramp, with sharp, knife-like or electrical pain, and the cramp can last for weeks.
- **Tingling and pins and needles,** which the NHS lists alongside numbness and weakness.
- **A mix in different places.** MedlinePlus says some people have sharp pain in one part of the leg or hip and numbness in other parts.
- **Anything from mild to severe.** MedlinePlus says it may feel like a mild tingling or dull ache, or be severe enough that you can’t move.

It usually affects one side. Cleveland Clinic says sciatica usually affects one leg at a time and only rarely both. Symptoms may come on suddenly or start slowly, according to the NHS.

## Where do you feel sciatica?

You feel sciatica along the path of the sciatic nerve: the lower back, buttock, back of the thigh, and the lower leg and foot. MedlinePlus says the nerve gives feeling to the back of the thigh, the outer and back part of the lower leg, and the sole of the foot. The NHS says symptoms usually affect your bottom and the back of one leg, often including your foot and toes.

The exact path depends on which nerve root is squeezed as it leaves your spine. Doctors use this map to work out where the problem is. The table below puts the American Family Physician nerve root table in plain words:

| Nerve root | Where pain or numbness tends to go | Movement that may feel weak | Reflex a doctor checks |
| --- | --- | --- | --- |
| L4 | Front of the lower leg and inner side of the foot | Straightening the knee | Knee jerk |
| L5 | Outer side of the lower leg and top of the foot | Pulling the foot and big toe up | Hamstring reflex behind the knee |
| S1 | Back of the leg and outer edge of the foot | Pushing the foot down, as when you stand on tiptoe | Ankle jerk |

A 2008 American Family Physician review adds two telling details. Numbness on the top of the foot best predicts an L5 problem. Weakness pushing the foot down and numbness on the outer heel best predict S1. Higher roots (L1 to L3) send pain to the hip and the front of the thigh, while L4 to S1 send it below the knee.

This is why your doctor may ask you to walk on your heels and toes, or squat and rise, as the AAOS describes. It’s a quick way to test each root.

## Is sciatica pain constant, or does it come and go?

Sciatica pain can be constant or come and go, and it often flares with certain movements. The AAOS says you may have pain especially when you move, sneeze or cough. MedlinePlus says it can be worse at certain times of day, such as at night. The NHS adds that sciatica can come back if you’ve had it before.

A useful way to track it is to rate your worst leg pain out of 10 each day, and note how far down your leg it reaches. Our guide to [how long sciatica lasts](https://nourishandstrong.com/how-long-does-sciatica-last) explains the signs that it’s on the mend.

## Why is sciatica worse when sitting or at night?

Sciatica is often worse when sitting if a slipped disc is the cause. The American Family Physician review says leg pain from a slipped disc worsens when sitting. Narrowing of the spine behaves differently. MedlinePlus lists these common triggers:

| Makes it worse | Often linked to |
| --- | --- |
| Sitting or standing for a while | Sciatica in general; sitting especially with a slipped disc |
| Sneezing, coughing or laughing | A slipped disc |
| Straining or holding your breath, such as on the toilet | A slipped disc |
| Bending backward, or walking more than a short distance | Spinal stenosis (narrowing of the spine) |
| Night or certain times of day | Sciatica in general |

Cleveland Clinic adds bending, and lifting your leg while lying on your back. That second one is the straight leg raise test doctors use. The American Family Physician review notes that stenosis pain often eases with rest or bending forward. If sitting is your trigger, see our tips on [lower back pain from sitting](https://nourishandstrong.com/lower-back-pain-from-sitting).

## How do you know if it’s sciatica or muscle pain?

You can usually tell sciatica from muscle pain by where it goes and how it feels. A pulled back muscle tends to cause aching across the back that’s worse when you move and better when you rest, the American Family Physician review says, with or without pain in the buttock. Pain from spine muscles, ligaments and joints can reach the thigh but rarely goes below the knee.

Sciatica is different in three ways. It usually travels below the knee. The leg hurts more than the back. And it often brings numbness, tingling or weakness, which a strained muscle doesn’t. The NHS puts it simply: if you only have back pain, you probably don’t have sciatica.

## How can you tell hip pain from sciatica?

Hip pain usually sits in the groin and hurts when you put weight on the leg or move the hip, while sciatica usually starts in the lower back, Cleveland Clinic says. The AAOS adds that hip arthritis pain spreads from the groin or thigh toward the knee. Several other conditions send pain down the leg too, including piriformis syndrome and bursitis. Our guide to [hip pain radiating down the leg](https://nourishandstrong.com/hip-pain-radiating-down-leg) compares all six side by side.

## When is sciatica an emergency?

Sciatica is an emergency when it affects both legs or comes with numbness around your genitals or bottom, or new bladder or bowel problems. These can be signs of cauda equina syndrome, which the AAOS calls a surgical emergency. The NHS says to go to the emergency department or call emergency services if you:

- Have sciatica on both sides
- Have weakness or numbness in both legs that’s severe or getting worse
- Have numbness around or under your genitals, or around your bottom
- Find it hard to start peeing, can’t pee, or can’t control when you pee, if that’s not normal for you
- Don’t notice when you need to poo, or can’t control it, if that’s not normal for you

Don’t drive yourself. Also get urgent help the same day if you have back pain with a fever or feel shivery and unwell, which the NHS lists as reasons for an urgent appointment.

## What should you do if you think you have sciatica?

If you think you have sciatica and none of the red flags apply, start with gentle movement and simple self-care. The NHS advice is:

- **Keep up your normal activities** as much as you can, and don’t sit or lie down for long periods. Moving may hurt, but it isn’t harmful.
- **Start gentle exercise** as soon as you can. Try these [sciatica exercises](https://nourishandstrong.com/sciatica-exercises).
- **Hold heat packs** on the painful areas.
- **Ask a pharmacist about pain relief.** The NHS says paracetamol is unlikely to help, and it isn’t clear how much anti-inflammatories help with sciatica.

See a doctor if the pain hasn’t improved after a few weeks, is getting worse, or stops you doing normal things. The AAOS says 80% to 90% of people with sciatica get better over time without surgery.

## Your next step

Tonight, sit for a minute and notice exactly where your symptoms run, then check the nerve root table above. Write down what you find, along with your worst pain out of 10. Then stand up and take a short, easy walk. If your pain starts in your lower back, a simple daily routine can help you keep moving.

## Quick questions

### How do I know if I have sciatica?

Sciatica usually causes pain from your buttock down the back of one leg, often into the foot, with tingling, numbness or weakness. The leg usually hurts more than the back, and coughing or sneezing can make it worse. The NHS says back pain on its own probably isn’t sciatica. A doctor can confirm it with a simple exam.

### Is sciatica pain constant?

It can be constant or come and go. The AAOS says sciatica pain is often worse when you move, sneeze or cough, and MedlinePlus says it can be worse after sitting or standing, or at certain times such as night. The NHS says it usually gets better in a few weeks to a few months, but can come back.

### Does sciatica affect both legs?

Usually not. Cleveland Clinic says sciatica usually affects one leg at a time and only rarely both. The NHS says sciatica on both sides, or weakness or numbness in both legs that’s severe or getting worse, needs emergency care, because it can be a sign of a serious problem in the spine.

### Can sciatica cause hip pain?

Yes. Cleveland Clinic says sciatic pain usually starts in the lower back and may travel into your hip or down your leg. The NHS says a slipped disc pressing on the sciatic nerve can cause pain in the buttocks, hips or legs. Hip joint problems more often cause groin pain, which can help tell them apart.

### Can sciatica cause foot pain?

Yes. The NHS says sciatica often reaches the foot and toes. Depending on which nerve root is squeezed, you may feel pain or numbness on the top of the foot, the inner side or the outer edge and heel. Weakness lifting the front of the foot, called foot drop, needs prompt medical attention.

### Is sciatica a muscle or nerve pain?

Sciatica is nerve pain. It happens when the sciatic nerve or one of its roots in the lower back is pressed or irritated, most often by a slipped disc. Muscle strains tend to ache across the back and rarely spread below the knee, while sciatica often does, with tingling or numbness.

This article is general information, not medical advice. Only a doctor who examines you can say whether your pain is sciatica and what’s causing it. If you have numbness around your genitals or bottom, new bladder or bowel problems, or sciatica in both legs, get emergency help straight away.
