Why Does My Back Hurt When I Sit Down?

If you find yourself constantly shifting in your chair, reaching for a cushion, or getting up every twenty minutes because your back is becoming uncomfortable, you’re certainly not alone.

Back pain when sitting is a common problem, particularly for people who spend long periods at a desk, driving, working from home or simply relaxing on the sofa. For some people, the pain gradually builds throughout the day. For others, sitting down can bring on an ache, stiffness or even pain that travels into the buttock or leg.

At Family Osteopathy in Hammersmith, we regularly see people experiencing back pain that is worse when sitting. While sitting itself isn’t necessarily harmful, spending long periods in one position can contribute to stiffness, muscle fatigue and irritation of already sensitive tissues.

The good news is that there are often simple changes that can help.

In this article, we’ll look at why your back might hurt when you sit down, common causes of sitting-related back pain, symptoms to look out for, and how osteopathy may help.

Why Does Sitting Make Back Pain Worse?

Sitting changes the way your body distributes load compared with standing or walking. Your hips and knees remain bent, your spine stays in a relatively fixed position, and it can be easy to gradually slump or lean to one side without realising it.

The problem isn’t necessarily that there is one “perfect” sitting posture that you need to maintain all day. In fact, staying in any position for too long can become uncomfortable.

Your body generally responds well to movement and variety. When you’re sitting for several hours with very few changes of position, muscles and joints can become stiff and tired, and an already irritated area may become more sensitive.

Some common effects of prolonged sitting include:

Increased load on the lower back

Sitting changes the position of your pelvis and lumbar spine and can increase loading through the lower back. Slouched sitting may increase this further, particularly if you remain in the position for a prolonged period.

Reduced movement

When you’re sitting at a desk for hours, your hips, pelvis and spine aren’t moving through their normal range very often. This can contribute to stiffness and discomfort when you eventually stand up or change position.

Muscle fatigue

The muscles around your back, abdomen and hips help support and control your movement throughout the day. Holding a relatively static position for long periods can lead to muscle fatigue and discomfort.

Your posture gradually changes

Most people don’t sit perfectly still. You might start the morning sitting upright and gradually end up leaning forward, rounding your shoulders or sitting on one side while concentrating on your screen.

This isn’t necessarily a problem in itself, but staying in the same position for a long time can make symptoms more noticeable.

Less movement throughout the day

Perhaps the biggest issue isn’t your chair at all — it’s simply that sitting often means you’re moving less.

Long periods at a desk can replace walking, changing position, stretching and other everyday movements. For many people, regularly breaking up sitting time can make a noticeable difference to how their back feels.

Common Causes of Back Pain When Sitting

There isn’t one single cause of back pain from sitting. Your symptoms may be influenced by several factors, including your work environment, activity levels, previous injuries and how your body responds to particular movements and positions.

Some common contributors include:

1. Prolonged Sitting and Desk Setup

An uncomfortable chair, poorly positioned screen or desk setup can make it harder to find a comfortable position.

If your screen is too low, you may spend more time looking down. If your chair or desk isn’t well suited to you, you may constantly adjust your position to find some relief.

Rather than searching for one “perfect” posture, the aim should be to create a comfortable workstation that allows you to change position and move regularly.

2. Muscle and Joint Stiffness

Spending a large part of the day sitting can contribute to stiffness around the hips, pelvis and lower back.

You may notice this particularly when standing up after sitting for a long time, getting out of the car or taking your first few steps after working at a desk.

3. Previous Injuries

An old injury doesn’t necessarily disappear from the picture simply because the original pain has settled.

Previous back, hip, pelvic or leg injuries can sometimes influence how you move or load your body. This may become more noticeable when you’re spending long periods in one position.

4. Disc-Related Back Pain

Problems affecting the discs between the vertebrae can sometimes cause pain that is worse with sitting, although this varies considerably between individuals.

Disc-related symptoms may sometimes include pain travelling into the buttock or leg, and may be accompanied by pins and needles, numbness or weakness.

If you experience these symptoms, it’s important to have them properly assessed rather than assuming that sitting is the only cause.

5. Irritation Around the Spinal Joints

The small joints at the back of the spine, known as facet joints, can sometimes contribute to back pain.

Certain positions or movements may aggravate these joints, and prolonged sitting can make symptoms more noticeable for some people.

6. Hip or Pelvic Factors

Your lower back doesn’t work in isolation.

The hips, pelvis and lower back all work together during everyday movements such as sitting, standing, walking and bending. Stiffness or discomfort in one area can sometimes influence how you move elsewhere.

This is one reason why an osteopathic assessment looks at more than simply the place where you feel the pain.

What Does Back Pain From Sitting Feel Like?

Sitting-related back pain can feel different from person to person.

You might experience:

• A dull or aching pain in your lower back

• Stiffness after sitting for a long time

• Pain that gradually builds throughout the day

• Discomfort when standing up after sitting

• Pain that improves when you walk or change position

• Tightness around your lower back, hips or buttocks

• Pain after a long commute or journey

• Sharp pain when changing position

• Pain that travels into your buttock, hip or leg

Sometimes, the most obvious clue is simply that your back feels better when you move.

When Should You Seek Medical Advice?

Most occasional back stiffness isn’t a reason to panic. However, you should seek appropriate medical assessment if your symptoms are persistent, worsening or significantly affecting your everyday life.

It’s particularly important to seek prompt medical assessment if you experience:

• New or worsening weakness in your legs

• Significant numbness or loss of sensation

• Numbness around the genitals or inner thighs

• Changes to bladder or bowel control

• Severe pain following a significant injury

• Back pain accompanied by other concerning symptoms such as unexplained weight loss, fever or feeling significantly unwell

These symptoms can occasionally indicate a condition requiring urgent medical assessment.

If your back pain has simply been hanging around for several weeks, is becoming more frequent or is interfering with work, exercise, sleep or everyday activities, it’s also worth getting it assessed rather than continually working around it.

How Can Osteopathy Help With Back Pain?

At Family Osteopathy in Hammersmith, we take the time to understand the individual pattern behind your back pain rather than assuming that every case has the same cause.

A Thorough Assessment

We’ll talk through:

• When your pain started

• Where you feel it

• What makes it better or worse

• How sitting affects your symptoms

• Your work and daily routine

• Previous injuries

• Your activity and exercise levels

• Any other symptoms you’re experiencing

We’ll then assess relevant areas such as your spinal and joint movement, muscle function and how different parts of your body work together.

The aim is to develop a clearer picture of what’s contributing to your symptoms and whether osteopathic treatment is appropriate.

Hands-On Osteopathic Treatment

Depending on your individual assessment, treatment may include techniques such as:

• Soft tissue techniques

• Joint mobilisation

• Spinal manipulation, where appropriate

• Myofascial techniques

• Gentle stretching and movement techniques

Treatment is always adapted to the individual rather than following a fixed routine.

Advice for Your Everyday Life

Treatment is only one part of managing back pain.

We’ll also discuss practical ways to make your day more comfortable, which may include:

• Adjusting your desk or workstation

• Changing your sitting position regularly

• Taking movement breaks

• Exercises or stretches that are appropriate for you

• Building more movement into your working day

• Gradually returning to activities you’ve been avoiding

The aim isn’t to make you afraid of sitting or movement. Instead, we want to help you understand your symptoms and gradually build your confidence and capacity.

Simple Things You Can Try Today

If your back becomes uncomfortable when sitting, there are a few simple things you can try.

1. Move regularly

Rather than trying to find the perfect sitting position, change position regularly.

Set a reminder if necessary and stand up, walk around or simply move your spine and hips every 30–45 minutes.

2. Check your workstation

Your chair, desk and screen should allow you to work comfortably without constantly reaching forward or looking down.

Your feet should be supported, and your screen should be positioned so that you aren’t spending hours with your head and neck angled downwards.

3. Don’t worry about sitting perfectly

There is no single posture that everyone needs to maintain all day.

Instead, think about posture as movement.

Sit upright for a while, move back in your chair, stand up, walk around and change position when you become uncomfortable.

4. Build more movement into your day

If you work at a desk, consider walking during phone calls, taking the stairs, having walking meetings where practical, or simply taking regular short breaks away from your screen.

Small amounts of movement throughout the day can add up.

5. Keep exercising where appropriate

If you’re generally well and exercise isn’t aggravating your symptoms, continuing to stay active is usually preferable to becoming overly cautious about movement.

If you’re unsure what exercise is appropriate for your particular symptoms, an assessment can help you work out where to start.

Why Does My Back Hurt When I Sit But Feel Better When I Stand?

This is a particularly common question.

If your back pain appears mainly when sitting and improves when you stand or walk, it doesn’t necessarily point to one specific diagnosis.

It may simply mean that your back is more comfortable with movement and changes in position than with prolonged sitting.

However, the pattern of your symptoms — including what movements make them better or worse, whether pain travels into your leg, and whether you have any neurological symptoms — can provide useful information during an assessment.

That’s why we look at the whole pattern rather than trying to diagnose your back pain from one symptom alone.

Getting Back to Comfortable Sitting

If sitting has become something you actively dread, you don’t necessarily need to resign yourself to it.

Back pain when sitting is common, but persistent or recurring pain is worth understanding.

Whether your symptoms are related to spending long hours at a desk, driving, a previous injury, reduced movement, muscular or joint factors, or something else entirely, the first step is working out what’s actually going on.

At Family Osteopathy in Hammersmith, we take a personalised approach to back pain and look at how your symptoms fit into your everyday life.

Our goal isn’t simply to help you feel better for a few days. It’s to help you understand your symptoms, improve your movement and build confidence in getting back to the things you enjoy.

If you’re experiencing lower back pain when sitting, or you’re finding that working at a desk, driving or relaxing at home is becoming increasingly uncomfortable, we’d be happy to help.
