Acute Neck Strain (Wry neck/toricollis)

Acute neck strain (wry neck / torticollis)

What is Acute neck strain?

Acute neck strain, also known as wry neck or torticollis, is a sudden onset of neck pain and stiffness that can make it difficult to move or hold the head in a normal position. It often presents as waking up with a “locked” or stiff neck that is hard to turn.

It is commonly caused by muscle spasm, awkward sleeping positions, sudden movement, or irritation of the joints and soft tissues in the cervical spine. In many cases, the neck muscles go into protective spasm, causing the head to feel tilted or rotated.

At Physio Elements in Kilsyth, treatment focuses on reducing pain and muscle spasm, restoring gentle movement, and helping the neck return to normal function as quickly and safely as possible.

What causes Acute neck strain?

Acute neck strain is commonly caused by:

  • Muscle spasm from awkward sleeping position
  • Sudden or uncontrolled neck movement
  • Joint irritation in the cervical spine
  • Poor posture or prolonged static positioning
  • Minor soft tissue strain in the neck muscles
  • Stress-related muscle tension contributing to spasm
  • Pre-existing neck stiffness or reduced mobility

Common symptoms of Acute neck strain?

  • Sudden onset of neck pain or “locked” neck
  • Significant stiffness and reduced range of motion
  • Head held in a tilted or rotated position
  • Sharp or localised pain on one side of the neck
  • Muscle tightness or spasm in the neck and shoulders
  • Pain that worsens with movement
  • Difficulty turning or straightening the neck

When should you see a physio for Acute neck strain?

You should see a physiotherapist if your neck becomes suddenly stiff, painful, or “locked,” especially if it limits your ability to move or carry out daily activities. You should also seek assessment if symptoms are severe, not improving within a few days, or are recurring. Early physiotherapy can help reduce muscle spasm, improve mobility, and speed up recovery.
