Back Pain From Desk Work: Why Posture Isn’t the Whole Story

As the day goes, you are starting to feel some pain in your lower back, shoulders. It might be slow, gradual process. A little stiffness at first. By the time you realise, you’re trying to stretch, roll your shoulders, and when you finally get up to go home, you feel like you’re learning to walk again.

Does it sound like you? Then hear me out.

We just love to blame the posture, don’t we? Since childhood, we’re told to sit up straight, stop slouching, pull our shoulders back or even buy a better chair. While a comfortable workstation can certainly make a working day easier, back pain is much more complicated than simply sitting in a “bad” position.

Our bodies are capable of sitting, slouching, bending and moving through many different positions. The problem is often less about finding the perfect posture and more about spending a long time doing the same thing.

There is no single perfect sitting position

Good ergonomics can be useful. If your screen position means you constantly twist to one side, your chair is uncomfortable or your mouse is so far away that you repeatedly reach for it, changing your setup makes sense. That’s different from believing there is one correct posture that will prevent back pain.

Research doesn’t show a simple relationship where sitting in a particular position automatically causes back pain. People naturally adopt different positions depending on their body, the task they’re performing and what feels comfortable.

Even a beautifully arranged ergonomic posture can become uncomfortable if you try to hold it rigidly for hours.

Instead of constantly correcting yourself back into one supposedly ideal position, it can be more useful to give yourself opportunities to change position throughout the day.

Why staying in one position can become uncomfortable

Sitting itself is not dangerous and doesn’t mean you’re slowly damaging your spine. What desk work often lacks is variety.

When work gets busy, it’s surprisingly easy to spend several hours with your hips and knees in roughly the same position, your hands around the keyboard and mouse. Especially, when the only thing holding your attension is the screen. The body may be doing relatively little large-scale movement while certain areas perform the same small tasks repeatedly.

Research involving office workers doesn’t show that simply spending more hours sitting inevitably causes lower-back pain. The relationship is more complex than that.

However, prolonged uninterrupted sitting and more static sitting behaviours may be associated with discomfort in some people,. Changing position or taking active breaks can be helpful.

That does not require turning your working day into an exercise class. Sometimes your body simply needs the opportunity to do something different.

What desk work asks from your upper back and shoulders

Working at a computer may look physically undemanding, but your upper body is not actually doing nothing.

Your arms need to be positioned while you type and use a mouse. Your shoulder blades provide a moving base for the arms, and muscles including the trapezius, rhomboids and other muscles around the scapula and thoracic spine are involved in controlling and supporting this region.

Meanwhile, the fingers and forearms may be performing hundreds of repeated movements through typing, scrolling and mouse use.

None of those activities is inherently harmful. Problems can arise when the workload exceeds what feels comfortable for that individual, particularly when there’s little variation throughout the day.

This can contribute to the familiar feeling of heaviness across the shoulders, aching between the shoulder blades, a tired neck or an upper back that feels as though it desperately wants to move. Only then we start rolling our head and move around, hoping this will solve the issue. But tomorrow we’ll do it all again.

The research around computer use and neck and shoulder pain isn’t completely straightforward either. Longer or more intensive computer work has been associated with symptoms in some studies, but the relationship is influenced by many factors. Computer work itself is not automatically damaging your shoulders.

Your lower back and hips are part of the same moving system

The lower back has its own workload during a day of sitting. The lumbar spine is surrounded by several layers of muscle. Larger muscles such as the erector spinae contribute to movement and control of the spine, while deeper muscles including multifidus work much closer to individual vertebrae.

However, the lumbar spine doesn’t work independently from everything below it. Your spine meets the pelvis, and the pelvis connects the trunk with the hips and legs. Muscles around the abdomen, back, pelvis and hips all contribute to the way we move and support ourselves during everyday activities.

When you sit, the hips also remain in a relatively consistent position. Again, that position isn’t inherently harmful. It’s simply very different from walking, standing, bending, climbing stairs or moving through the many other positions our bodies are capable of using.

This is why lower-back discomfort doesn’t necessarily mean that the exact painful patch of lumbar muscle is the only area worth considering and caring for.

When somebody tells me their lower back becomes uncomfortable during their working day, I’m interested in more than whether they “sit properly”. Where is the discomfort? How long are they usually sitting before it appears? Do they get opportunities to move? Does walking make it feel different? Are the hips or gluteal area uncomfortable too? What happens outside their working day? Maybe they sit half the day at work, and then go for a 10 mile walk with a dog after.

Those details tell me far more than whether someone happens to slouch.

It is not only about sitting

Desk work is often described as sedentary, but some parts of your body can be extremely busy.

Typing involves repeated finger and wrist movements. Mouse use repeatedly involves the hand and forearm while the arm is positioned from the shoulder. Phones, multiple monitors and frequently used items placed around the desk may add reaching and turning. Your forearms and wrists probably need some attention too.

A laptop creates different demands from a desktop setup, and someone working from a sofa for an hour has different options from somebody spending eight hours at the same workstation. And I shall know, I’m sitting cross-legged on my sofa in this very moment.

Workload outside the office matters too. Someone who sits at a desk all day and then trains at the gym, cares for young children, works on home renovations has a very different overall physical workload. Someone else’s day will look completly different.

Sleep, stress, previous episodes of pain, general activity and individual differences can all affect how we experience discomfort.

That’s why two people can use virtually identical desks and chairs and have completely different backs. Because they have also completly different bodies, needs and so on.

Movement does not need to be complicated

You don’t need to perform a ten-minute stretching routine every half an hour to look after your back at work. Small changes count.

You might stand while taking a phone call, walk to get some water, change how you are sitting reguraly, move your shoulders and neck occasionally or take a short walk during your lunch break. If you have a sit-stand desk, it can provide another position to move between rather than a reason to stand rigidly for the rest of the day.

If part of your workstation consistently feels awkward, changing it is also sensible. A comfortable chair, an appropriately positioned screen and keeping frequently used equipment within easy reach can reduce unnecessary effort.

The aim isn’t to spend your entire working day monitoring your posture. It’s to make movement and variation easier.

How can massage help with desk-related back pain?

When somebody comes to me because their back starts aching during or after work, I don’t automatically assume that their posture needs correcting.

I want to know where they feel the discomfort, what their working day actually involves and which other areas feel tired or restricted. The answer can change how I approach their massage.

For someone experiencing upper-back and shoulder tension, treatment may involve the thoracic back, muscles around the shoulder blades, shoulders and neck. Depending on their symptoms, I may also work the upper arms, forearms or chest because these areas are involved in the same everyday upper-body activities. And with desk job, there’s a fair chance the upper chest is tight, pulling the shoulders forward. That’s why often stretching your back and shoulders, doesn’t give you the relief you’re looking for.

For lower-back discomfort, I might not spend the entire treatment repeatedly pressing into the lumbar area either. Because the lower back works alongside the pelvis and hips, it can sometimes make sense to include the gluteal muscles, hips or surrounding tissues where appropriate.

This doesn’t mean that tight glutes are automatically “causing” your back pain, any more than tight shoulders automatically explain a headache. It means I am treating a person who moves as a whole rather than a painful bit of muscle.

Massage can provide short-term relief from muscular soreness, stiffness and tension and offer a period of comfortable movement and relaxation. Research into massage for back pain has produced mixed results, and it shouldn’t be presented as a cure or as a way of correcting spinal alignment.

For recurring back pain, massage generally makes more sense alongside staying active and moving regularly rather than replacing those things. It’s a method of pain management, support in many ways and definately worth getting.

However, it’s not a cure. And even more definitely not in just one session.

Massage cannot undo sitting, because sitting hasn’t damaged you

You may occasionally hear massage described as something that “undoes” the effects of sitting at a desk. I’d be cautious with that idea.

Sitting at work doesn’t mean your muscles have become permanently shortened or your spine has moved out of place. A massage therapist isn’t pushing your skeleton back into alignment after a week in an office chair.

What massage can do is address muscles that currently feel sore, tired or tense. It can provide temporary symptom relief, help you relax and make movement feel more comfortable. That’s why you come out feeling somewhat more lose, like you’re floating even.

That’s useful without needing a dramatic explanation about correcting your body.

When back pain needs more than a massage

Most episodes of back pain are not caused by a serious medical problem and often improve with time and activity. However, new, severe, worsening or unexplained pain should not automatically be blamed on desk work.

The NHS recommends urgent medical assessment for back pain accompanied by symptoms including: weakness, tingling or numbness in both legs, loss of sensation around the genitals or anus, or changes to bladder or bowel control. Back pain following a serious accident or accompanied by chest pain also requires urgent assessment.

If something feels substantially different from your usual muscular aches and pains, getting it appropriately assessed is more important than assuming you simply need a deeper massage.

Your back needs options, not perfection

A comfortable workstation is worthwhile, and changing something that repeatedly makes you uncomfortable is sensible. What you don’t need is to spend eight hours frightened of slouching or constantly forcing yourself into a rigid position.

Your upper back, lower back, shoulders, hips and arms are all designed to move. Desk work simply gives them fewer opportunities to use that variety unless we deliberately put some movement back into the day.

Sit comfortably. Change position. Stand sometimes. Walk when you get the chance. Adjust the things that genuinely feel awkward.

And if your muscles are feeling particularly tired after a long week at your desk, that is where massage comes in.
