Shoulder pain from computer work

Shoulder pain from computer work tends to show up in one of two places. For many people it is a heavy, tight ache across the top of the shoulder, in the band of muscle between the neck and the point of the shoulder, that builds through the day. For others it is deeper, at the front or side of the shoulder joint, and it catches when they lift the arm or reach behind them. The two have different causes and different warning signs, so it helps to know which one you are dealing with.

This page explains what the research says links computer work to shoulder pain, what has been shown to help, and when to stop managing it yourself and see a doctor.

Where the pain usually comes from

The top of the shoulder: muscles

The muscle that forms the slope between your neck and shoulder is the upper part of the trapezius. Underneath it, the levator scapulae runs from the neck down to the shoulder blade. Both attach to the shoulder blade and help lift and steady it.

Pain in this part of the trapezius has been linked with monotonous work such as computer work, and when it lasts, doctors may diagnose it as trapezius myalgia, a muscle pain condition (Andersen et al., 2008). A review of 22 studies in which disorders were confirmed by a physical examination found limited evidence that computer work, and time spent using a mouse, are linked with tension neck syndrome, a muscle pain condition of the neck and upper shoulders. For tendon problems in the shoulder joint, the evidence was insufficient to show any link with computer work at all (Wærsted et al., 2010).

This kind of shoulder pain often travels with neck pain. NHS inform notes that neck problems can cause pain in the shoulders, arms and upper back (NHS inform), so if the ache starts in your neck, the page on neck pain from desk work is also worth reading. If it sits lower, between the shoulder blades, where the rhomboids lie, see pain between the shoulder blades.

The joint itself: tendons and the rotator cuff

Pain that is worse when you use your arm can come from the tendons, or from the small fluid-filled sacs (bursae) around the shoulder joint. The NHS lists tendonitis, bursitis and impingement as possible causes of that pattern. Pain and stiffness that lingers for months points more towards frozen shoulder or arthritis, and pain right on top of the shoulder, where the collarbone meets the shoulder joint, can come from the joint there (NHS).

These problems are more strongly tied to other kinds of work. A 2024 review of work-related shoulder disorders found the strongest evidence for working with the arms raised, repetitive movements, force and vibration. It also found that psychosocial pressures at work were linked with rotator cuff problems (Versloot et al., 2024). Desk work involves little lifting above shoulder height, so if your shoulder joint hurts, it is worth thinking about the gym, the garden or DIY as well as the desk, and getting it properly assessed.

How common is it?

Common, and early. When 632 people starting new jobs with at least 15 hours a week at a computer were followed for up to three years, new neck or shoulder symptoms appeared at a rate of 58 cases per 100 person-years (roughly, per 100 people followed for a year), and disorders confirmed on examination at 35 per 100 person-years. Nearly half of the neck and shoulder symptoms (46%) appeared in the first month (Gerr et al., 2002).

The reassuring part comes from a Danish study of 2,146 technical assistants. Most of them had no or only minor neck and shoulder pain, few had prolonged pain, and even fewer had chronic pain (Andersen et al., 2008).

What causes shoulder pain from computer work?

Time on the mouse

A review of nine long-term studies found moderate evidence that the more time people spend using a mouse, the more likely they are to develop hand and arm symptoms. The links for the neck and shoulder were weaker than for the hand and arm (IJmker et al., 2007).

The Danish study took the question further by logging mouse and keyboard use with software rather than asking people to estimate it. When people were split into four equal groups by weekly mouse time, the risk of short-term shoulder pain rose by about 10% with each step up. But mouse and keyboard time did not predict who went on to have prolonged or chronic shoulder pain. The number of clicks and keystrokes, and how often people paused, made no difference either. A few psychosocial factors did predict prolonged pain (Andersen et al., 2008).

So a long mouse-heavy day can leave your shoulder sore, but on this evidence it is not, by itself, what turns a sore shoulder into a long-term one. That is useful to know if your job, like graphic design, is built around a mouse.

How your arms are supported

In the study of 632 new computer users, some details of the setup made a difference to neck and shoulder symptoms (Marcus et al., 2002):

• a chair with armrests went with a lower risk
• typing with the elbows lower than the middle row of the keyboard went with a higher risk
• using a telephone shoulder rest, the clip that lets you hold a handset between ear and shoulder, went with a higher risk

Forearm support has also been tested directly. In a year-long trial with 182 call centre staff, a wide forearm support on the desk, alongside ergonomics training, halved the rate of new neck and shoulder disorders diagnosed by a blinded doctor (hazard ratio 0.49), and reduced neck and shoulder pain (Rempel et al., 2006).

Stress and tension

When you are under pressure, the muscles of the neck and shoulder tend to work harder. A review of 25 studies found that simulated workplace stressors, such as mental stress, time pressure and work demanding precision, produced a medium-sized increase in neck and shoulder muscle activity during computer work. Nearly all of those studies were done in a laboratory, so how much this matters in a real office is not known (Eijckelhof et al., 2013).

Will it settle on its own?

Often, but not always quickly. The NHS says you usually need to keep up self-care for about two weeks before shoulder pain starts to ease, and that recovery can take six months or longer (NHS). If it is getting worse, or has not improved after two weeks, the NHS advises seeing a GP rather than waiting it out.

What the research says helps

Keep the shoulder moving

NHS advice is to stay active and move the shoulder gently, not to stop using it, and to use pain relief so that you can keep moving. It also suggests resting your arm on a cushion in your lap and sitting with a cushion behind your lower back, and warns against making up your own strenuous exercises or using heavy gym equipment (NHS).

Strengthening for muscle pain at the top of the shoulder

The best evidence for desk-related shoulder muscle pain comes from strengthening trials. In a Danish trial, 48 women in monotonous jobs, such as computer-intensive work, with diagnosed trapezius myalgia were assigned to ten weeks of strength training for the painful muscles, general fitness training on an exercise bike, or no training. Strength training reduced their worst pain by about 79%. The cycling group had only a small, short-lived drop in pain (Andersen et al., 2008).

In a later trial with 198 office workers with frequent neck and shoulder pain, 2 minutes of strengthening a day, on five workdays a week, cut pain by 1.4 points on a 10-point scale over ten weeks compared with health information alone. Twelve minutes a day cut it by 1.9 (Andersen et al., 2011). A review of 27 workplace trials agreed that strengthening of the neck and shoulders reduced pain in office workers who already had it (Chen et al., 2018). Is two minutes of exercise enough? looks at that two-minute result in more detail.

Those trials used specific programmes with progression, so the details matter. A physiotherapist can set one up for you.

For the joint, a diagnosis comes first

Pain from the tendons or joint needs a different approach depending on the cause. The NHS describes a health professional examining the shoulder, sometimes arranging an X-ray, and then choosing treatment, which may include physiotherapy, exercises at home, medicines or injections, or a specialist referral (NHS). In many areas you can refer yourself to NHS musculoskeletal services without a GP. If you are considering private care, see how much physiotherapy costs.

Workstation changes with some evidence behind them

Desk changes are not a cure, and the research on them is patchier than most office guidance implies. But a few have more support than others.

Give your forearms somewhere to rest. Between the forearm support trial and the armrest finding above, this is the change with the most direct evidence. A Cochrane review of 15 trials found moderate-quality evidence that an arm support combined with an alternative mouse reduced new neck or shoulder disorders (risk ratio 0.52, two trials). The same review judged the evidence for arm supports and alternative mice overall to be inconsistent: an alternative mouse on its own, or an arm support with an ordinary mouse, did not clearly help (Hoe et al., 2018). Our guide to setting up your office chair covers armrest height.

Set the desk and chair so your elbows are not below the keyboard. Use the desk height calculator for a starting point based on your height, then adjust from there. On a laptop this is harder, and working on a laptop without straining your neck explains the options. For a whole room at home, see the home office setup guide.

Do not hold the phone with your shoulder. A telephone shoulder rest went with a higher risk in the study of new computer users (Marcus et al., 2002), so a headset or speaker is the better choice for long calls.

Break up long mouse sessions, but do not expect miracles. The Cochrane review found very low-quality evidence that extra breaks reduced discomfort in the neck and right shoulder among data entry workers (Hoe et al., 2018), while in the Danish logging study, short pauses made no difference to pain (Andersen et al., 2008). Breaks are still a sensible habit, and the guide to microbreaks suggests ways to make them stick.

When to see a doctor

This site does not replace a doctor or physiotherapist, and with shoulder pain a few symptoms need prompt attention.

Call 999 if you have chest pain that feels tight or like squeezing, or chest pain that spreads to your arm, neck or jaw. Shortness of breath, feeling sick and sweating can come with it. These can be signs of a heart attack, and pain in the arm or shoulder should not be put down to the mouse when they are present (NHS).

Ask for an urgent GP appointment or contact NHS 111 if (NHS):

• you have sudden or very bad shoulder pain
• you cannot move your arm
• your arm or shoulder has changed shape or is badly swollen
• you have pins and needles that do not go away, or no feeling in your arm or shoulder
• your arm or shoulder is hot or cold to the touch
• the pain started after an injury or accident, such as a fall
• you have severe pain in both shoulders
• you feel feverish or unwell

See a GP if your shoulder pain is getting worse or has not improved after two weeks, or if it is very difficult to move your arm or shoulder (NHS).

One more pattern to know about if you are over 50: pain and stiffness in the muscles around the shoulders, neck and hips, with morning stiffness that lasts longer than 45 minutes, can be a sign of polymyalgia rheumatica. The NHS advises seeing a GP if you have had pain and stiffness like this for more than a week (NHS).

Where Bavelu fits

Bavelu’s sessions for the neck, shoulders and upper back are designed and filmed by physiotherapists, and the two to four minute desk routines, guided by your AirPods, are meant for the gaps in a mouse-heavy day. A short questionnaire about where it hurts and how long you spend at the computer shapes your plan. It is exercise guidance, not a diagnosis or treatment, so a shoulder joint that hurts when you lift your arm, or anything in the list above, should be checked by a professional first.
