Best Pillow for Post-Concussion Syndrome (2026): What Helps

Written by Bogdan Bilt · independent, reader-supported · not a clinician · how I research

If you are weeks past a concussion and still waking with a headache, a stiff neck and the feeling that sleep is not doing its job, this page is for you. It is not a page about treating a concussion. It is about the part of the problem that lives in the neck, which is the only part a pillow can reach, and about knowing the difference.

Concussion, Post-Concussion Syndrome and the Neck

The Cleveland Clinic describes a concussion as a head injury in which the brain moves or twists inside the skull, and says most last a few weeks, up to a month. When symptoms go on longer, the label changes. The Mayo Clinic defines persistent post-concussive symptoms as those lasting beyond three months, usually appearing within 7–10 days of the injury and sometimes continuing for a year or more. Its symptom list is long: headaches (often migraine-like or tension-type), dizziness, fatigue, trouble falling asleep or sleeping too much, poor concentration, irritability, sensitivity to light and noise, and neck pain.

That last item is the one this page is about. The force that concusses a brain also loads the neck. A blow to the head, a fall, a collision on the pitch or in a car, all whip the head on the neck hard enough to strain the joints, ligaments and muscles of the upper cervical spine. In practice that means most people with a concussion also have a whiplash-type neck injury, whether or not anyone has called it that. Physiopedia’s review of post-traumatic cervicogenic headache cites figures of around 90% of concussed athletes reporting headache, 90% reporting neck pain and roughly 69% reporting dizziness, and notes that whiplash accounts for up to 53% of cervicogenic headaches.

The reason the neck matters so much is anatomical. The nerves from the top three neck segments (C1–C3) feed into the same relay in the brainstem, the trigeminocervical nucleus, that handles pain from the head and face. Irritation in the upper neck gets read by the brain as a headache. So a strained upper neck does not just hurt as a neck. It produces the headache, and often the dizziness, that get filed under “post-concussion” and treated as though they were untouchable.

What This Does to Your Nights

During the day you move, and a strained neck gets some variety. At night it gets one position for seven or eight hours, chosen by the pillow. If that position is rotated (stomach sleeping, or a side pillow that lets the head tilt), extended (a flat or collapsed pillow that lets the head drop back) or flexed (a tall pillow that pushes the chin down), the irritated upper-neck joints spend the night being irritated, and you wake with the headache already running.

There is a second, more specific problem. Many post-concussion headaches start at the base of the skull, where the suboccipital muscles attach and the greater occipital nerve passes. A pillow that presses hard into that spot, or that puts the weight of the head on it all night, is a pillow that starts the headache before you are awake. A cradle that spreads the load across the back of the head and takes the neck’s weight from underneath is the shape that avoids this. If pressure at the back of the skull is the whole story for you, the occipital neuralgia guide goes into it in more detail.

And sleep itself matters. Both the NHS and the Cleveland Clinic are clear that you do not need to be kept awake after a concussion and that sleep is part of the recovery. Anything that stops you sleeping, including a neck that will not settle, is working against you.

The Loft Numbers

The ranges are the same as for other upper-neck injuries: roughly 7–10 cm on your back and 10–14 cm on your side, measured with your head on the pillow rather than the box height. The post-concussion adjustment is about precision and stillness rather than a different number.

Body build still moves the number. A soft mattress that lets the shoulder sink needs less pillow on the side; broad shoulders on a firm mattress need more. The pillow height calculator gives a starting figure for your build.

Positions to Use and Avoid

Back sleeping (usually best)

Nothing rotated, load symmetrical, and a contour can fill the neck from below so the upper-neck joints are supported rather than hanging. Keep the chin level. If you are in the light-sensitive phase, this is also the easiest position to keep an eye mask in place.

Side sleeping (fine if the height is right)

The rule is a level head: ear over shoulder, nose pointing straight ahead rather than down at the mattress. A pillow between the knees stops the lower spine twisting and pulling the neck with it. If one side of the neck is worse, most people find lying on the better side more comfortable.

Stomach sleeping (avoid)

Face-down means the head turned hard to one side for hours, on a neck that has just been strained. A body pillow along your front is the usual way to stop yourself rolling onto it.

Slightly elevated (sometimes useful early on)

Some people find a modest incline eases the headache in the first weeks. If so, raise the whole torso with a wedge under the mattress or shoulders rather than stacking pillows under the head, which flexes the neck. Our recliner sleeping guide covers the setup if a chair is where you are managing to sleep.

What to Look for in a Pillow

• A cradle, not a flat surface. The back of the skull should sit in a shallow hollow that spreads the load, with the neck supported from underneath. That is the shape that keeps pressure off the suboccipital region.
• Height that holds. A pillow that is right at 11pm and flat by 2am drops the neck into extension for the second half of the night. Feather, down and cheap polyester do this; high-density memory foam and latex do not.
• Two heights on one pillow. Concussion recovery is a restless time. A lower centre for the back and higher edges for the side means turning does not mean folding or stacking.
• Medium-firm. Firm enough to hold the shape, soft enough that the head settles rather than balances on it.
• A quiet, cool cover. Light and noise sensitivity are common; a cover that does not crackle or run hot is worth having.

Our Pick: The Derila Ergo

The Derila Ergo is the pillow we recommend for the neck part of post-concussion recovery because it does the two things that matter here. The contour fills the neck and cradles the head so the weight is spread rather than concentrated at the base of the skull, and the medium-firm memory foam holds its height, 9 cm at the centre for back sleeping and 12 cm at the edges for side sleeping, all night. At the time of writing it is $59.99 for one or $99.98 for two, with a 60-day money-back guarantee, which is long enough to cover the adjustment period on a neck that is still healing. Our full Derila review covers the build, the cover and the complaints.

Not for you if:

• You are in the first few days after the injury, or have any of the red flags below. Get seen first.
• You have not had the neck assessed. A concussion is a head injury; the neck is often not examined. If you have neck pain, ask for it to be looked at, and ask about physiotherapy.
• You sleep on your stomach. The contour makes that position worse.
• You have broad shoulders and a soft mattress, or narrow shoulders and a very firm one. The Derila comes in one height; check the calculator first, and if your number is well outside 9–12 cm an adjustable pillow suits you better.

What the Pillow Cannot Do

It cannot speed up the brain’s recovery, and it will not touch the fatigue, the concentration problems or the mood changes. What it removes is a nightly aggravation of the neck injury that sits underneath many of the physical symptoms. That is worth having, but it is a supporting role.

The things with evidence behind them for the neck part are physiotherapy and graded exercise. Physiopedia’s review reports that adding manual therapy for the neck produced a significant fall in headache intensity at three and six months in the studies it cites, and that sub-symptom-threshold aerobic exercise safely speeds recovery. If nobody has assessed your neck since the injury, that is the appointment to make. If the headache pattern is clearly one-sided and set off by neck movement, the cervicogenic headache guide covers that headache specifically, and if the injury was a collision, the post-accident neck pain guide covers the whiplash timeline.

When a Pillow Is Not the Answer: The Red Flags

A concussion that is getting slowly better, with a headache that is easing week by week and a neck that is stiff but improving, is what recovery normally looks like. The following are different, and they are emergencies. The Cleveland Clinic and the NHS list them as reasons for immediate emergency care (999 in the UK, 911 in the US):

• A headache that is getting worse, or a sudden severe headache
• Repeated vomiting
• Increasing confusion, drowsiness you cannot be roused from, or a change in behaviour
• A seizure, or being knocked out and not waking
• Unequal pupils, new problems with vision or hearing
• Clear fluid or blood from the nose or ears
• New weakness, numbness or difficulty with speech or walking

Those can mean bleeding inside the skull, and no amount of pillow adjustment is the right response. Separately, the Mayo Clinic advises seeing a doctor for any concussion symptoms that are not improving, and for new confusion, memory loss, vision changes or nausea even if you were never knocked out. Neck pain with numbness or weakness into the arms, or pain that started with a high-speed impact and has not been imaged, also needs assessment before you settle into any sleep setup.

Frequently Asked Questions

What is the best pillow for post-concussion syndrome?

A contoured memory-foam or latex pillow that holds the upper neck neutral, at roughly 7–10 cm on your back or 10–14 cm on your side, and cradles the back of the head so the weight is not concentrated at the base of the skull. The pillow helps the neck-injury part of the symptoms, not the brain injury. The Derila Ergo (9 cm centre, 12 cm edges) is our pick.

Why does my neck hurt after a concussion?

Because the force that shook the brain also whipped the neck. Most concussions come with a whiplash-type strain of the upper cervical joints and muscles, and around nine in ten concussed athletes report neck pain in the figures Physiopedia cites. The neck is often not examined after a head injury, so it is worth asking for it to be assessed.

Can a pillow help post-concussion headaches?

It can help the ones that come from the neck. Upper-neck pain is relayed through the same brainstem nucleus as head pain, so an irritated upper neck produces a headache. A pillow that keeps the neck still and neutral, and does not press on the back of the skull, removes a night’s worth of that irritation. It does nothing for migraine-type or purely brain-driven headaches.

Should I sleep with my head elevated after a concussion?

Some people find a modest incline more comfortable in the early weeks, and there is no harm in it if it helps you sleep. Raise the whole torso with a wedge rather than piling pillows under the head, which bends the neck. Flat is fine if it is comfortable. Sleep itself is the priority; both the NHS and the Cleveland Clinic say you do not need to be kept awake.

How long does post-concussion neck pain last?

The concussion itself usually settles within a few weeks. Persistent post-concussive symptoms are defined as those lasting more than three months. Neck strain follows a whiplash-type timeline and often improves faster with physiotherapy; if the neck pain and headache are not improving after a few weeks, ask for a cervical spine assessment rather than waiting it out.
