You go to bed feeling fine and wake up with your head stuck slightly to one side. Checking your blind spot is out of the question, and the sharp catch when you try to turn stops you dead. That’s a wry neck, and it’s one of the most common reasons people ring a physio clinic hoping to be seen that day.

The good news is that most wry necks settle well. The trick is working out which type you’ve got and what to do in the first couple of days. It also helps to know the handful of situations where a stiff, twisted neck needs a doctor before it needs a physio.

What is a wry neck?

Wry neck is the everyday name for acute torticollis, which literally means twisted neck. The head sits turned or tilted to one side, the muscles down one side of the neck are in spasm, and certain movements are blocked by pain. People often search for “wry neck disease”, but healthdirect describes torticollis as a physical sign rather than a disease. That’s a useful way to think about it. The twisted neck tells you something is being protected, but it doesn’t tell you what. healthdirect

The term covers a few different conditions, which causes some confusion. Babies can be born with congenital muscular torticollis, where a tight neck muscle holds the head tilted, usually without much pain. Cervical dystonia is a neurological condition where the neck muscles contract involuntarily over months or years. This article is about the acute version that turns up overnight or with a quick turn of the head, and usually settles within days to a couple of weeks.

What causes a wry neck?

Each vertebra in your neck is linked to the next by two small facet joints at the back, one on each side. These are the joints that glide when you turn or tilt your head. At the front, between the vertebrae, sit the discs. When we assess a wry neck, we’re mostly trying to work out which of these is driving it, because the two behave quite differently.

Facet wry neck is the more common type, particularly in teenagers and younger adults. It comes on suddenly, either on waking or with a quick movement like turning to reverse the car. The pain is sharp and sits in one spot you can often point to with a finger. The head is usually held turned and tilted slightly away from the sore side, and moving back towards it is where the catch lives. There’s often one position where it feels almost fine until you move.

The leading explanation for why a facet joint “locks” involves small folds of tissue inside the joint called meniscoids. Mercer and Bogduk’s anatomical work in 1993 described these folds in the cervical facet joints. A later cadaver study found meniscoids in 86% of the cervical facet joints examined. The idea is that one of these folds gets pinched between the joint surfaces during an awkward movement, a bit like a curtain catching in a door hinge. The joint hasn’t “gone out”, but it becomes painful to move one way, and the surrounding muscles clamp down to stop you moving further. That spasm is what gives you the tilted head. To be fair, meniscoid entrapment is still a theory, since nobody has watched it happen in a living neck, but it fits the clinical picture well. springer springer

Discogenic wry neck tends to build over hours rather than arriving in an instant. People often go to bed with a slightly sore neck and wake up much worse. The pain is more of a spread-out ache that can refer into the shoulder blade or down the arm, and it’s harder to find a comfortable position. It’s more typical once you’re past about 30, as the discs become more sensitive to sustained load.

As for triggers, most people want a reason and often there isn’t a satisfying one. Sleeping with your head turned hard to one side, nodding off on the couch or on a long flight, or spending a morning looking up while painting a ceiling are all classic stories. Posture gets a lot of the blame, but the evidence linking any particular sitting posture to neck pain is mixed. Plenty of people with textbook posture get a wry neck. What the neck really doesn’t like is being held in one position for hours, whatever that position is.

How long does a wry neck last?

A facet wry neck usually eases noticeably within the first 48 hours. Healthdirect puts typical recovery at 7 to 10 days, although a bit of residual stiffness, or a sense that you don’t quite trust it yet, can linger a little longer. Discogenic wry necks are slower and can take a few weeks to settle fully. If there’s arm pain or pins and needles, the timeline depends on how irritated the nerve is. healthdirect

Many wry necks will settle on their own. Seeing a physio early mostly shortens the painful part and confirms which type you’re dealing with. The biggest thing in your control is how you handle the first few days. Keeping the neck gently moving generally beats holding it rigid and waiting, which is why a soft neck collar isn’t recommended for acute torticollis. patient

How to unlock a wry neck at home

This is one of the most searched questions about wry neck. The honest answer is that you can’t really unlock it yourself by forcing it. Trying to crack your own neck, or having someone pull on your head, tends to make the spasm worse. What you can do is create the conditions for the joint to settle and the muscles to let go.

Start with heat. Gentle heat is one of the standard self-care recommendations for torticollis, and a heat pack or warm shower for 10 to 15 minutes before moving makes the exercises below easier. Simple pain relief can take the edge off enough to let you move, and your pharmacist or GP can advise what suits you. healthdirect

Then move little and often. A short routine every hour or two does more than one long session at night:

Sit upright in a supported chair with your shoulders relaxed. Slowly turn your head towards the side that moves easily, as far as is comfortable, then back to centre. Repeat 5 to 10 times.
Turn a small way towards the stiff side, stopping at the first sign of the catch rather than pushing into it. Return to centre and repeat 5 to 10 times. The range often creeps a little further with each set.
Make slow, small nodding movements, as if saying yes, 5 to 10 times.
Finish with a few shoulder rolls and a gentle squeeze of the shoulder blades together to ease the upper back.

None of this should produce sharp pain. Mild discomfort at the edge of the range is fine, but a sharp catch means you’ve gone as far as the neck will allow for now.

Sleep is usually the worst part. Aim for a pillow height that keeps your head level with your spine, so the neck isn’t propped up or dropping down. Lying on your back or on your more comfortable side suits most people, and a rolled hand towel inside the pillowcase supports the curve of the neck nicely. Avoid sleeping on your stomach while it’s sore, since that holds the neck in full rotation for hours.

Physiotherapy for wry neck

The first job is assessment. Your physio will check:

which movements are blocked and which are free
where the pain sits
whether anything is referring into the arm
nerve function and the red flags below

That’s what separates a straightforward facet wry neck from a disc irritation or something that needs medical referral, and treatment differs for each.

For a facet wry neck, gentle joint mobilisation is usually the main tool. These are small, slow, rhythmical movements applied to the stiff level of the neck, well within your comfort. They encourage the joint to glide again and give the guarding muscles a reason to relax. Soft tissue work and mobilising the upper back usually help too. This lines up with the 2017 neck pain clinical practice guideline published in the Journal of Orthopaedic & Sports Physical Therapy. For acute neck pain with restricted movement, it recommends thoracic manipulation, neck range-of-motion exercise and strengthening around the shoulder blades, with cervical mobilisation or manipulation as an option. Facet wry necks often respond quickly to this, especially when they’re treated in the first day or two. jospt

Discogenic presentations need a more careful touch. Treatment focuses on finding the positions and movements that ease the disc and settling the spasm. Movement is then progressed as the irritability comes down. Where there’s arm pain, your physio will keep a close eye on nerve symptoms from session to session. Either way, you’ll leave with a short home program matched to how your neck is moving on the day. You can read more about how our physiotherapy team approaches assessment and treatment.

When a stiff neck needs a doctor first

The vast majority of wry necks are mechanical and settle well, but a small number of stiff, twisted necks have a different cause.

Get urgent medical care if a stiff neck comes with fever, severe headache, vomiting, sensitivity to light or a rash, as that combination can signal meningitis. The same applies if the neck became painful after a fall, car accident or heavy knock. It also applies if you notice weakness, numbness or pins and needles in both arms, trouble with balance or walking, or difficulty swallowing or speaking.

In children, a wry neck that follows a sore throat, ear infection or recent throat or ear surgery should be checked by a GP, because inflammation in the throat can occasionally affect the upper neck joints. A baby who consistently holds their head tilted to one side is more likely to have congenital muscular torticollis, which a GP or paediatric physio can assess.

If your neck keeps pulling or twisting to one side over weeks without the usual sudden-onset story, or there’s a tremor, see your GP. That pattern points towards cervical dystonia, which is managed very differently. Any wry neck that isn’t clearly improving after a week or two is also worth having assessed.

Stopping it coming back

Some people get one wry neck in their life. Others get one every year or two, and those are the people worth spending more time with once the acute pain has gone.

Recurrent wry necks often come with a stiff upper back and deep neck muscles that tire quickly when you hold your head up for long periods. The deep neck flexors, which sit along the front of the spine and hold the neck steady, are a good example. Building their endurance with simple, low-load exercises, alongside strength work for the shoulder blade muscles, gives the neck more capacity to cope with long days at a screen or an awkward night’s sleep. The same guideline recommends neck and shoulder girdle endurance exercise once neck pain moves past the acute stage. It’s also the part of rehab people most often drop as soon as the pain goes. orthopt

Beyond that, changing position every half hour or so during long desk sessions, and replacing a pillow that leaves you waking stiff, covers most of the practical side.

If your neck has locked up and isn’t easing within a couple of days, our physiotherapists in Grange can assess what’s driving it and help get it moving. You can also read more about how we manage neck pain and headaches, or book online.
