What Is Torticollis, and Why Is My Neck Stuck to One Side?
Torticollis, sometimes called wry neck, is a condition where the neck muscles tighten or spasm, pulling your head into a tilted or rotated position to one side. It can happen suddenly in adults or be present from birth. The cause ranges from a simple muscle spasm to an underlying problem in the cervical spine that needs investigation.
- Torticollis means your head is tilted or twisted to one side because of muscle tightness or spasm in the neck.
- In adults it often comes on suddenly (acute wry neck) and usually settles within days, but persistent cases need investigation.
- In babies it is called congenital muscular torticollis and is usually caused by tightness in a muscle called the sternocleidomastoid.
- Standing imaging shows how a neck tilt affects the whole spine, revealing compensations that lying-down scans can miss.
- If you have numbness, weakness, or difficulty swallowing alongside a twisted neck, seek urgent medical attention.
What does torticollis look and feel like?
Torticollis is usually easy to spot. Your head leans to one side, and you may find it painful or impossible to straighten it. Here are the common signs.
What causes torticollis?
Torticollis happens when the sternocleidomastoid muscle, or another neck muscle, shortens or spasms. The trigger depends on the type.
Why does acute wry neck happen in adults?
Acute wry neck usually strikes without warning, often after a night's sleep or a quick head turn. The muscles on one side of the neck go into spasm and lock your head in a tilted or rotated position.
Most episodes are self-limiting and settle within a few days with gentle movement, warmth, and over-the-counter pain relief. But when the problem keeps coming back, or it does not resolve within a week or two, it is worth investigating further.
A persistent head tilt changes the alignment of your whole spine. Your body is a connected chain from your skull to your feet. When the head sits off-centre, the shoulders, mid-back, and pelvis adjust to compensate. Over time, this can cause pain in places far from the original problem, including a cervical tilt that becomes habitual.
If your wry neck keeps returning or your head tilt will not go away, a standing whole-body image can show the full picture. Book a free video consultation
What is congenital muscular torticollis in babies?
Congenital muscular torticollis is the most common form of torticollis in babies. It is caused by tightness or shortening of the sternocleidomastoid muscle on one side of the neck, usually from the baby's position in the womb or during delivery.
Parents usually notice a head tilt in the first weeks of life. The baby may prefer to look one way and have difficulty turning the other way. Sometimes a small, firm lump can be felt in the affected muscle. If left unaddressed, it can lead to a flattened area on the skull (plagiocephaly) and uneven facial development.
Early physiotherapy stretching is the standard approach and is effective in most cases. Your GP or paediatrician will guide you. If imaging is needed to check the cervical spine, paediatric imaging at ScanAlign uses an EOS system that delivers about 90% less radiation than a standard X-ray, around ten times less. This matters when the patient is a child.
How is torticollis assessed with standing imaging?
A standing, weight-bearing image captures your neck and spine in the position they actually work in. When you lie down for a conventional X-ray or MRI, gravity is removed. Your muscles relax, and a tilt or compensatory curve may flatten out, making the image look more normal than the reality.
With ScanAlign, low dose standing imaging, the EOS system takes a full-length image of your skeleton while you stand naturally. This reveals the true position of the cervical spine in relation to your shoulders, ribcage, pelvis, and legs. Your clinician can then see exactly how a persistent tilt is affecting the rest of your alignment.
The EOS system uses about 90% less radiation than a standard X-ray, around ten times less. This is especially important if repeat imaging is needed to track changes over time.
When MRI is the better choice: EOS excels at showing bones, joints, and alignment. If your clinician suspects a disc problem, nerve compression, or a soft-tissue cause for your torticollis, MRI is usually the better tool. The two work well together.
When should you see a doctor urgently for a twisted neck?
Most acute wry neck episodes are uncomfortable but harmless. However, some symptoms alongside a twisted neck need urgent medical attention. Contact your GP, call 111, or go to A&E if you experience any of the following:
- Numbness, tingling, or weakness spreading into your arms or legs.
- Difficulty swallowing or breathing.
- Loss of bladder or bowel control.
- A twisted neck following a fall, head injury, or accident.
- Fever, severe headache, or neck stiffness that could suggest infection or meningitis.
These signs do not necessarily mean something serious, but they need to be ruled out quickly by a medical professional.
Frequently asked questions about torticollis
They mean the same thing. Torticollis is the medical term, from the Latin for "twisted neck." Wry neck is the everyday English name for the same condition.
Most episodes settle within a few days to two weeks with gentle movement, warmth, and simple pain relief. If it lasts longer than two weeks or keeps coming back, see your GP for further assessment.
Yes. A persistent head tilt forces the rest of the spine to compensate. This can lead to shoulder pain, mid-back stiffness, or even lower back and hip discomfort over time.
Cervical dystonia, also called spasmodic torticollis, is a specific neurological form. It involves involuntary, sustained muscle contractions and is a long-term condition managed by a neurologist. Most cases of torticollis are muscular and much simpler.
No. ScanAlign accepts self-referrals. You can book an assessment directly without a GP letter.
Yes. The EOS system uses about 90% less radiation than a standard X-ray, around ten times less. The scan takes only seconds while you stand still, so it is well tolerated even with a stiff neck.
Yes. The low radiation dose makes EOS well suited to younger patients when imaging is clinically needed. ScanAlign offers paediatric imaging for children referred by their clinician or parent.
The sternocleidomastoid is a large muscle on each side of your neck. It runs from behind the ear down to the collarbone and breastbone. When one side tightens or shortens, it pulls the head into a tilt.
ScanAlign is a private, self-pay clinic. For current pricing and what is included, please visit the FAQs and cost page.
When you lie down, gravity is removed. Your muscles relax and a tilt can flatten out, making the scan look more normal than reality. Standing imaging captures your spine under real weight-bearing conditions, showing the true position and any compensations happening further down the body.
