Quick Summary
Acute wry neck (torticollis) is a sudden, painful locking of the neck to one side that often appears overnight, so you wake with your head stuck and unable to turn it comfortably. It is common, usually not serious, and typically settles within 24–48 hours — occasionally taking up to a week to resolve fully.
Our physiotherapists can help ease pain and restore movement sooner with gentle manual therapy, reassurance and a simple exercise plan. Most people need only a small number of sessions, and we tailor everything to your individual assessment.
What Is Wry Neck (Acute Torticollis)?
Acute torticollis — literally “twisted neck” — is a sudden-onset condition in which the neck muscles on one side go into painful spasm, holding your head tilted and rotated to one side. The muscles most often involved are the sternocleidomastoid, trapezius and levator scapulae, and typical features are sudden severe one-sided pain, restricted movement and the neck deviating towards the affected side.
The exact mechanism is debated. Leading theories include irritation of a small facet joint at the back of the neck — sometimes with entrapment of a tiny, well-innervated synovial fold (a meniscoid) between the joint surfaces — protective muscle spasm, or minor irritation of a muscle, ligament or disc. In most cases no specific structural cause is ever identified, and imaging such as X-ray is not needed unless a more serious cause is suspected.
The natural history is reassuring. Acute torticollis usually resolves within 24–48 hours, occasionally taking up to a week, although recurrence is common. (NICE CKS, 2023) Research on acute neck pain in general practice also shows a favourable natural course for most people. (Vos et al., British Journal of General Practice, 2007)
It is important to distinguish this common adult wry neck from congenital muscular torticollis (present from birth or early infancy) and from cervical dystonia (spasmodic torticollis), a chronic neurological movement disorder managed very differently. This page is about the acute, self-limiting adult wry neck that responds well to physiotherapy.
Do You Experience These Symptoms?
✓ Sudden-onset neck pain and stiffness, frequently first noticed on waking
✓ The neck held locked or twisted to one side, difficult to straighten
✓ Sharp pain on attempting to move or turn your head, especially towards the painful side
✓ Muscle spasm and tenderness along one side of the neck
✓ Pain that may spread to the back of the head, shoulder or upper back
✓ Difficulty with everyday tasks such as driving or checking a blind spot
✓ Occasional associated headache
These symptoms can be treated.
The sooner you begin, the better your chances of a smoother recovery.
What Causes Wry Neck (Acute Torticollis)?
• Awkward sleeping position
Sleeping without adequate head and neck support, or in an unusual position, is one of the most common triggers, which is why people typically wake with symptoms. The muscles and joints of the neck can become irritated after being held in a strained position for hours.
• Sudden or unguarded movement
A quick, awkward turn of the head — during sport, exercise or simply reaching — can trigger protective muscle spasm and joint irritation. This may lock the neck to one side within minutes to hours.
• Prolonged poor posture and cold exposure
Long periods at a screen, poor desk ergonomics, or exposure to a cold draught can irritate neck muscles and ligaments. Poor posture and awkward positioning are recognised contributors to acute torticollis.
• Stress and muscle tension
Emotional stress and general tension raise resting muscle tone in the neck and shoulders. This can make the cervical muscles more vulnerable to spasm and minor strain.
• Minor facet joint or ligament irritation
Minor irritation of a small cervical facet joint, its inner synovial fold, or a supporting ligament is a widely proposed mechanical cause. This fits the typical “locked” quality of the neck and its good response to gentle movement and mobilisation.
How We Treat Wry Neck at J&J Therapy
Hands-On Manual Therapy
Our HCPC-registered physiotherapists begin with a careful assessment to confirm acute wry neck and rule out more serious causes. We then use gentle, hands-on techniques to ease pain and restore movement, including soft-tissue work to the sternocleidomastoid, trapezius and levator scapulae to reduce muscle spasm, and gentle cervical mobilisation to restore comfortable range of motion. Evidence shows early, active movement leads to better recovery than rest or a collar, so our manual therapy always goes hand in hand with keeping your neck gently moving.
Shockwave Therapy*
Swiss Storz Medical MASTERPULS shockwave therapy is not a first-line treatment for acute wry neck, which usually settles with manual therapy, gentle movement and exercise. Where your assessment shows persistent myofascial trigger points in the trapezius or levator scapulae are contributing to ongoing symptoms, radial shockwave may complement your manual therapy and exercise programme when your physiotherapist identifies specific indications. Non-invasive, with honest guidance on its evidence limitations for your individual case.
Targeted Exercise Programme
Once the acute pain begins to ease, we guide you through gentle active range-of-motion exercises, moving the neck a little in each direction within comfortable limits. As symptoms settle we progress to gentle stretching and strengthening of the neck and shoulder-girdle muscles, alongside postural and ergonomic advice for sleeping, desk setup and screen use. Research suggests exercise has the strongest long-term evidence for neck pain, and it also helps reduce the chance of recurrence.
When to Seek Urgent Medical Help
While most symptoms are not serious, urgent medical attention is required if you experience any of the following:
Fever, feeling generally unwell, or swollen neck glands — this may point to infection rather than a simple mechanical wry neck
Onset after significant trauma, such as a road accident or a fall from height
Weakness, numbness or pins and needles in the arms or hands, problems with balance or walking, or loss of bladder or bowel control
Severe, unremitting or worsening pain, or pain that disturbs your sleep — particularly with unexplained weight loss or a history of cancer
FAQs About Wry Neck
How long does wry neck last?
Most cases of acute wry neck improve within 24–48 hours, and the great majority settle within a week. Physiotherapy may help ease pain and restore movement more quickly, and reduce the chance of it coming back.
Should I rest it or keep moving?
Keep it gently moving. Research and UK guidance show that early, gentle movement leads to better outcomes than resting, and soft neck collars are not recommended because they can prolong stiffness. Move within comfortable limits and let pain guide you.
What is the best way to sleep with a wry neck?
Use a single low, firm, supportive pillow that keeps your head level with your spine, and sleep on your back or side rather than your front. Applying a wrapped heat pack for up to around 20 minutes before bed may help relax the muscles.
When should I see a physiotherapist or GP?
You can see a physiotherapist at any point if you want help easing pain and restoring movement, or if symptoms are severe. See your GP or contact NHS 111 if symptoms last longer than about a week, keep recurring, or if you develop any of the urgent symptoms listed above.
Is shockwave therapy used for wry neck?
Not as a first-line treatment. Acute wry neck usually settles quickly with gentle movement, manual therapy and exercise, and there is no good evidence that shockwave helps the acute locked neck itself. If your assessment shows chronic muscular trigger points are keeping your symptoms going, your physiotherapist may discuss shockwave as one possible complement — always with an honest explanation of the limited evidence.
