You went to bed fine. You woke up and your neck had decided otherwise: locked over to one side, a hard band of pain down from your ear, and turning your head to check the mirror is now a whole-body manoeuvre. Nothing happened. You didn't fall, you didn't get hit. It was just a pillow, or a long flight, or a quick glance over your shoulder yesterday afternoon.
That's acute wry neck, and it's more alarming than it is dangerous.
Your neck muscles have gone into spasm. Australia's public health service defines torticollis exactly that way (the muscles of your neck spasm or cramp, causing pain and stiffness and twisting the neck to one side) and is careful to add that it's a physical sign, not a disease in its own right 1. Something set it off; the spasm is the response, not the problem.
In adults, what set it off is nearly always mundane. Wry neck can occur at any age but turns up most in teenagers and young adults, and the usual triggers are sleeping in an awkward posture, a sudden flicking or jerking of the head, carrying a heavy unbalanced load like a suitcase on one side, or a viral infection 3. Sitting in a cramped position on a flight, or a night in an unfamiliar bed, is enough on its own 1.
Three broad types exist: congenital (present from birth), acquired (the injury-or-trauma kind, which covers almost every adult case) and spasmic 1. This page is about the acquired kind.
Most stiff, twisted necks are muscular. Not all of them are, and the list of alternatives is longer than most people expect: trauma including fracture or dislocation, infection in the head, neck, spine or chest, inflammatory conditions, a reaction to certain medications, eye problems, and rarely a tumour 1,2.
A few practical distinctions:
It followed an accident or a collision. Trauma sits at the top of the differential for a reason 2. If your neck locked up after a car accident or a heavy tackle, that's a different pathway: see Whiplash.
It started after a new medication. Some drugs cause an acute dystonic reaction that looks very much like wry neck: metoclopramide, an anti-nausea medication, is the one guidelines name specifically 2. Mention it to your GP before you assume you slept badly.
You're over 40, or it keeps coming back. Wry neck is more common in younger people, and in rare cases, particularly over 40, there's an underlying medical condition behind it, not a mechanical one 3. Recurrent, grumbling neck trouble between episodes is usually a different story again: see Neck Pain.
A straightforward wry neck is worked out from your story and an examination. You'll be asked how long it's been there, whether you slept or sat awkwardly, whether there was an injury, whether you've been unwell, and what medicines you've taken 2. Then the clinician presses along the middle of your spine for tenderness, watches how far you can turn your head on your own, and checks your nerves, eyes, throat and the glands in your neck 2.
An X-ray of the neck comes into it if the spine itself is tender, the pain is severe, or you're still stuck after a week 2. Fever, signs of infection or any nerve changes mean imaging to find the cause 2.
The first appointment is mostly working out which of the above you have. We take the history properly (what you were doing, what you've taken, whether you've been unwell), check how the neck actually moves, and screen for the red flags further down this page. That triage is the most valuable part, because the treatment for uncomplicated wry neck is straightforward and the treatment for everything else isn't.
For a straightforward acute wry neck:
If it happened during sport (a sudden jerk of the head is one of the named triggers 3), the return-to-training side of it is something our sports physiotherapy work covers.
On how strong the evidence actually is. We'd rather be straight about this than oversell it. The largest analysis of hands-on treatment for torticollis pooled 100 randomised trials and more than 8,000 participants, and did find real short-term improvements in neck rotation and head posture when manual therapy was added to active treatment, but the authors graded the certainty of that evidence as very low to low for every outcome, because of risk of bias, small studies and inconsistency between them 4. That analysis also looked at infants, not adults, so it doesn't transfer neatly here either. The pathway and the prognosis are well agreed. How much any one technique contributes is not.
A heat pack is standard first-line advice from both Australian government sources, and from the paediatric guideline that covers the same presentation in children 1,2. Simple, cheap, and it makes moving the neck tolerable enough to actually do it.
Recommended alongside heat for an uncomplicated wry neck 1,2. Useful for comfort and for settling the spasm enough to move, not a treatment to build a recovery around on its own.
Clinical guidelines list basic analgesia as appropriate treatment for most uncomplicated cases 2. Physiotherapists don't prescribe or administer medication; that's a conversation for your GP or pharmacist. We mention it because pain relief that lets you move the neck is doing more work than the pain relief alone suggests.
Congenital muscular torticollis is managed with a structured physiotherapy program of stretching, strengthening and repositioning, set out in the current professional-body clinical practice guideline 5. Early referral matters, and it's not the same treatment as the adult version of this: full detail in Torticollis in Babies.
A wry neck is a short episode, so the phases of The Well Motion Recovery Path™ can pass in days. You move up on how the neck turns, not on the day count.
How long it usually takes. Symptoms usually disappear completely within 7 to 10 days, depending on the cause 1,2. That figure comes from government health guidance, not from a study that followed adults with wry neck, and a neck still stuck after a week needs assessing 2.
Nobody has run a trial on preventing wry neck itself. What we do have is a short list of named triggers, plus one tested result for neck pain in general:
Most wry necks settle on their own inside a fortnight. A few shouldn't be managed at home at all, and it's worth knowing which before you're in the middle of one.
Get urgent medical care if the neck symptoms come with a fever, more drooling than usual, a sore throat, trouble breathing or swallowing, changes to your vision, or any change in feeling or movement in your arms or legs 1,2. Headache with double vision, light sensitivity or unsteadiness belongs in the same group 2.
Speak to your GP if it started shortly after a new medication 2, or if you're over 40 and this has come out of nowhere 3.
Book an assessment if you're still stuck after about a week. That's not an arbitrary number: persistent symptoms at a week, or significant tenderness over the spine, is the point at which guidelines recommend imaging the cervical spine instead of waiting longer 2. It's also the point where an episode that should have resolved hasn't, and that's worth knowing in itself.
If your neck locks up after hours, on a weekend or a public holiday, and you have none of the urgent or GP signs above, our after-hours emergency physiotherapy can come to you. Call (02) 8111 5633.
For most people none of that applies and the neck loosens over several days. The advice is simple: heat, movement and patience.
We start by listening: how it began, what makes it worse, and what it's stopping you from doing. Then we examine the area, explain what we find in plain English, and agree a plan with you. Your first visit is 40 minutes at Engadine and 30 minutes at our other clinics.
We see patients at Engadine, Mount Annan, Narellan and Appin, and at home through our mobile physiotherapy service. If you have private health cover, here's how health fund rebates work for physiotherapy.
Usually 7 to 10 days. Australia's public health service says symptoms usually disappear completely within 7 to 10 days, depending on the cause 1, and Australian clinical guidelines use the same window for uncomplicated acute torticollis 2. Treated early, it often responds within a few days 3. Past about a week with nothing shifting is the point to get it looked at properly 2.
For an adult, usually not much. Most uncomplicated cases resolve on their own inside that 7-to-10-day window 1,2. The thing to watch is whether it lingers: symptoms still there at a week are exactly what guidelines treat as the trigger for further assessment 2. Untreated congenital torticollis in an infant is a different question, and the consequences are more significant: a permanent head tilt, changes to the shape of the head and face, and knock-on effects for the spine, jaw and eyes 1. That's why infant torticollis gets referred early instead of watched.
There isn't a single prescribed "best" position in any source we'd trust, so we won't invent one. What is supported: avoid sitting or lying with your neck in an awkward position 3, sleep with a small pillow so your head and neck stay in line with your body 1, and don't sleep on your stomach, which forces your neck fully turned to one side all night 3. For side-sleeping, the distance between the side of your neck and your shoulder is a reasonable guide to the pillow height you need 3.
Both ends of life, for different reasons. Congenital muscular torticollis is present from birth or shows up in the weeks and months after it 1,5. The acquired kind (the sudden wry neck this page is about) can occur at any age, but is most common in teenagers and young adults 3.
