Why Your Neck Hurts by 3pm — And How to Fix Your Office Setup

Sore neck by 3pm? Nagging headache? Most desk-related neck pain comes down to a few fixable things, and one that no gadget can solve.

Why desk work causes neck pain and headaches

Your head weighs about five kilograms. When it sits balanced over your shoulders, the muscles of your neck have very little to do. Push it forward a few centimetres (like in the 1st image above) to read a screen that sits too low, and those muscles have to hold it there all day. That is why the ache builds through the afternoon rather than being there when you wake up.

The muscles that complain first are usually the ones across the top of the shoulders and at the base of the skull. Keep them switched on for hours and two things tend to follow: a deep ache where the neck meets the shoulder, and headaches.

Desk-related headaches generally come in two forms. Tension-type headaches feel like a band of pressure around the head and build as the day goes on. Cervicogenic headaches start in the neck and refer up into the back of the head, behind the eye or into the temple.

They happen because the nerves carrying sensation from your upper neck and from your head arrive at the same relay point in the brainstem, so the brain has trouble telling one from the other. It is also why these headaches are often one-sided and travel with a stiff neck.

If you clench your jaw while you concentrate, the same pattern can drive jaw pain as well. We have written separately about jaw pain and TMJD.

Start with the basics

•      Chair. Sit right back so your lower back is supported. Feet flat, knees roughly level with your hips. If your feet dangle, use a footrest — a ream of paper works.

•      Desk height. Elbows at about a right angle, forearms level with the desk.

•      Screen. Top of the screen level with your eyes, about an arm’s length away.

•      Avoid working on a laptop alone. A laptop forces a compromise: set the screen at the right height and the keyboard is too high or set the keyboard right and you spend the day looking down. Either raise the laptop and add a separate keyboard or add a monitor and leave the laptop screen off. Dual screens are the best option if you have the space.

•      Keyboard and mouse. Close enough that your elbows stay by your sides.

That last point matters more than people expect. Studies measuring muscle activity during mouse use found that resting the forearm on the desk cut shoulder muscle effort dramatically, and people felt noticeably more comfortable.¹

Sit-stand desks

Height-adjustable desks and desktop risers do change behaviour. A recent review found people using them cut their sitting time by roughly an hour a day, and were still doing so a year later.² Workplace schemes including sit-stand workstations reduced sitting by around 70 minutes per eight-hour day, far more than reminders alone.³

One caveat: the evidence shows sit-stand desks reduce sitting time, not that they cure back pain. And standing still all day has its own costs. Alternate, perhaps 20–30 minutes standing each hour, and build up gradually.

Vertical mice

A standard mouse holds your forearm palm-down, so the muscles that rotate it work the whole time. A vertical mouse holds your hand in a “handshake” position instead, and lab measurements show less activity in those forearm muscles with differently shaped mice.⁴

Many people with wrist or forearm niggles find one more comfortable, and it is low-risk to try. Two things to know: the research base is small, so treat it as worth experimenting with rather than proven, and it feels clumsy for a week or two. Give it a fortnight before judging.

My go-to is the Logitech MX Vertical. It connects over Bluetooth, so there is no dongle to lose or to take up valuable USB space, and it is rechargeable, so no batteries. You can also pair it with several devices and switch between them easily. It sits at the expensive end for a mouse, but it is worth the investment. I have used plenty of others and this one comes out on top, hands down. Well, hand perpendicular to the desk J .

The thing equipment can’t fix

Your body doesn’t like holding any position for long, however good that position is. The best posture is the next one. Every half hour, stand up, walk to the kettle, roll your shoulders, or take a call on your feet. Five two-minute breaks beat one long stretch at lunchtime.

How osteopathy can help with neck pain and headaches

Fixing your set-up removes the cause. It does not always settle tissue that has been irritated for months, and that is where treatment comes in.

We start by working out what is actually driving your symptoms, and whether the problem is muscular, coming from the joints of the neck and upper back, or a combination of the two.

Treatment usually combines hands-on work to release the tight muscles across the shoulders and at the base of the skull, gentle movement of the neck and upper back joints, and exercises to build endurance in the deep muscles that hold your head up. We will also go through your ideal work ergonomic position with you, because that is the part that stops it coming back.

Trials of manual therapy for cervicogenic headache report reductions in both headache frequency and neck pain, with improvements still present at six-month follow-up.⁵ That matches what we see in practice. Most people notice a change within a few sessions, provided the desk gets sorted out too. Treatment on its own, with the set-up left as it was, tends to buy a temporary reprieve rather than a fix.

When to get it checked

Pins and needles, numbness, weakness in the hand, or pain waking you at night are worth having assessed rather than adjusting your chair again, as are symptoms that haven’t settled after a few weeks of improving your set-up. The same goes for headaches that are becoming more frequent, or that are not responding to the usual measures.
