Back Pain vs Sciatica: How to Tell the Difference

02/11/26

We've all experienced the occasional twinge in our back. Perhaps you've lifted something awkwardly, spent too long sitting at your desk or woken up feeling stiff and uncomfortable.

But what happens when that pain starts travelling into your buttock or down your leg? Is it still back pain, or could it be sciatica?

It's a question we hear regularly at Back to Health, and it's easy to understand why. Back pain and sciatica can feel similar, but they're not quite the same thing.

Understanding the difference can help you make sense of your symptoms and know when to seek advice.

What's the Difference Between Back Pain and Sciatica?

Back pain is one of the most common musculoskeletal complaints, and most of us will experience it at some point in our lives.

It can feel like a dull ache, a sharp twinge or stiffness that makes bending, twisting or getting out of bed uncomfortable. The pain usually stays around your lower back, although it can sometimes spread into your buttocks or thighs.

Sciatica is different because it involves irritation or compression of a nerve in your lower spine.

The sciatic nerve runs from your lower back, through your buttocks and down your legs. When one of the nerve roots that contributes to this nerve becomes irritated, you may experience pain, tingling or numbness travelling into your leg.

Interestingly, some people with sciatica experience very little back pain at all. Their main complaint is the pain travelling down their leg.

How Can You Tell if It's Sciatica?

One of the biggest clues is where you feel the pain and how it behaves.

Typical signs of lower back pain include:

• An ache or sharp pain around your lower back.

• Stiffness when bending, twisting or getting up from sitting.

• Tight or uncomfortable muscles around your back.

• Pain that may spread into your buttocks or upper legs.

Common symptoms of sciatica include:

• Shooting, burning or electric-shock-like pain travelling down one leg.

• Tingling or pins and needles in your leg or foot.

• Numbness or changes in sensation.

• Weakness in the affected leg or foot.

• Pain that becomes worse when sitting, coughing or sneezing.

Sciatica usually affects one leg, although it can occasionally affect both.

A useful rule of thumb: If your pain travels below your knee, particularly with tingling or numbness, sciatica becomes more likely. However, not all leg pain is sciatica, and the location of your pain alone isn't enough to make a diagnosis.

What Causes Back Pain and Sciatica?

Sometimes back pain develops after an obvious event, such as lifting something heavy or spending a weekend gardening. Other times, it appears without any clear reason.

Muscles, joints and other structures around your spine can all contribute to back pain.

Sciatica is more specifically associated with irritation of a nerve root in your lower back.

One possible cause is a herniated disc, sometimes called a slipped disc. This happens when part of a spinal disc bulges or pushes outwards and irritates a nearby nerve.

Age-related changes in the spine can also sometimes narrow the spaces around nerves, contributing to symptoms.

However, it's important to remember that changes seen on an X-ray or MRI don't always explain someone's pain. Many people have disc bulges or age-related spinal changes without experiencing any symptoms.

What Can You Do to Help Yourself?

If you're struggling with back pain or sciatica, it's natural to want to rest until the pain disappears.

However, for most people, keeping gently active is one of the best things they can do.

Here are a few simple ways to help manage your symptoms.

1. Keep Moving

You don't need to push through severe pain, but try not to spend long periods resting in bed.

Short walks, gentle movement and continuing with comfortable everyday activities can help prevent stiffness and maintain your confidence in moving.

2. Change Position Regularly

Sitting for long periods can aggravate some types of back pain and sciatica.

If you work at a desk or spend a lot of time driving, try taking regular breaks to stand, stretch or walk around.

There's no perfect sitting position, so focus on staying comfortable and changing position regularly.

3. Try Heat or Cold

A warm compress or hot water bottle may help ease muscle tension, while a cold pack can provide temporary relief for some people.

Always protect your skin with a towel and avoid applying heat or cold to areas where you have reduced sensation.

4. Don't Be Afraid to Move

It's understandable to become cautious when your back hurts, particularly if certain movements have caused pain before.

However, avoiding movement altogether can make it harder to return to your normal activities.

Start with movements you can manage comfortably and gradually build up as your symptoms improve.

5. Know When to Ask for Help

Most episodes of lower back pain improve over time, and sciatica often settles with appropriate care.

But if your symptoms are persistent, getting worse or affecting your sleep, work or everyday life, it's worth getting them assessed.

You don't need to wait until the pain becomes unbearable before seeking advice.

How Can Chiropractic, Osteopathy and Physiotherapy Help?

At Back to Health, we regularly see patients who aren't quite sure whether they're experiencing ordinary back pain, sciatica or something else entirely.

That's why your first appointment begins with a conversation about your symptoms, medical history and how the problem is affecting your everyday life.

Your Chiropractor, Osteopath or Physiotherapist will then carry out an appropriate examination, which may include checking your movement, muscle strength, reflexes and sensation.

This helps us understand what may be contributing to your symptoms and whether treatment is appropriate.

Depending on your individual needs, care may include hands-on treatment, exercises to improve movement and strength, and practical advice on managing your symptoms at home.

For back pain and sciatica, manual therapy may be considered alongside exercise and advice rather than as a treatment on its own.

Sometimes the most useful thing we can do is explain what's happening, reassure you about movements that are safe and help you gradually return to the activities you've been avoiding.

And if your symptoms suggest you need further medical investigation or specialist care, we'll advise you on the appropriate next steps.

When Is Back Pain or Sciatica More Serious?

Although most back pain and sciatica aren't caused by anything serious, there are some warning signs that need urgent attention.

Go to A&E immediately if you develop:

• New difficulty passing urine or loss of bladder or bowel control.

• Numbness around your genitals, bottom or between your legs.

• New or rapidly worsening weakness in your legs, particularly if both legs are affected.

• Severe back pain with new symptoms affecting both legs, such as numbness or weakness.

These symptoms can sometimes indicate a rare but serious condition called cauda equina syndrome, which requires emergency assessment.

You should also seek prompt medical advice if you develop back pain following a significant injury, have a fever or unexplained weight loss alongside your symptoms, or notice progressive weakness.

Don't Let Back Pain or Sciatica Take Over Your Day

Whether it's struggling to get comfortable at your desk, finding it painful to walk the dog or being woken up by discomfort during the night, back pain and sciatica can have a real impact on everyday life.

The good news is that many people improve with time, appropriate advice and a gradual return to normal activity.
