What is a neck muscle strain?
The neck contains many muscles that support and move the head (trapezius, levator scapulae, sternocleidomastoid, scalenes and deep neck extensors). A strain is an overstretch or small tear in muscle fibres, and a sprain involves ligaments. Because the head weighs about 4–5 kg and is held at the top of a flexible column, small mechanical stresses can overload these muscles, particularly with sustained poor posture. See contractura cervical (Spanish).
Common causes
- Sleeping in an awkward position or on a poor pillow.
- Prolonged forward head posture: desk work, phones, tablets, driving.
- Sudden movements, carrying heavy bags on one shoulder, sports and gym work.
- Minor falls, whiplash and collisions.
- Stress and muscle tension.
- Cold drafts and lack of movement.
Symptoms
- Pain and tightness at the back or side of the neck, sometimes spreading to the shoulder or upper back.
- Stiffness and limited rotation, with pain on turning the head.
- Muscle spasm and tenderness to touch.
- Headache at the base of the skull in some people.
- Pain that may be worse in the morning or after sitting.
- No arm weakness, numbness or tingling in simple strains.
Self-care in the first days
- Keep moving gently: avoid prolonged immobilisation; avoid neck collars beyond a day or two.
- Heat (warm shower, heat pack) for 15–20 minutes helps relax muscles; cold may ease acute pain; use whichever feels better.
- Pain relief: paracetamol or, if suitable, a short course of ibuprofen; topical anti-inflammatory gels.
- Gentle exercises within comfort (see below).
- Sleep with a supportive pillow that keeps the neck neutral; avoid sleeping on your stomach.
- Take breaks from screens and change posture every 30 minutes.
- Self-massage or light massage may help comfort.
Gentle neck exercises
- Chin tucks: gently draw the chin back, hold 5 seconds, 10 repetitions.
- Neck rotations: turn the head slowly to each side within comfort, 10 each side.
- Side bends: ear towards the shoulder, hold 15–20 seconds each side.
- Shoulder rolls and shoulder blade squeezes: 10–15 repetitions.
- Upper trapezius stretch: gently tilt and lightly assist with the hand, 20–30 seconds, 2–3 times.
- Isometric holds (pressing the head lightly into the hand in each direction), 5 seconds each.
- Progress to light strengthening of the neck and upper back once pain eases. See upper-back exercises (Spanish) and trapezius contracture (Spanish).
How long does it last?
Most neck strains improve within a few days and resolve in 1–3 weeks. Moderate strains may take 4–6 weeks. Pain lasting more than 6–12 weeks is classed as persistent and benefits from a structured programme of exercise, ergonomic changes and, when appropriate, manual therapy. Recurrence is common without addressing posture, workstation and strength.
Posture and workstation tips
- Raise the screen so the top is at or slightly below eye level and arm’s length away.
- Use a chair with back support, feet flat and elbows at about 90°.
- Hold your phone at eye level or use hands-free for long calls.
- Alternate sitting and standing; take a movement break every 30–45 minutes.
- Carry bags on both shoulders or use a backpack with both straps.
- Strengthen deep neck flexors and upper back muscles.
- Keep active with regular exercise and manage stress.
When to see a doctor
- Pain after a significant injury (fall, collision).
- Arm or hand numbness, tingling or weakness.
- Severe headache, fever, stiff neck or confusion (emergency).
- Difficulty walking, balance problems or loss of bladder or bowel control.
- Pain at night that does not ease with positions, or unexplained weight loss.
- No improvement after 2–4 weeks, or recurrent episodes.
Three common situations
Waking with a stiff neck after an awkward sleep: heat, gentle movement and simple painkillers; improvement within days.
Neck and shoulder tension after weeks of long desk hours: adjust your workstation, take breaks and strengthen the upper back.
Neck pain with arm tingling: may involve a nerve root; see a doctor.
Choosing a pillow and sleeping position
A good pillow keeps your head level with your spine: for back sleepers, a thinner pillow with a small neck roll; for side sleepers, a pillow high enough to fill the space between the ear and the shoulder. Avoid stacking several pillows or sleeping on your front with the neck twisted. A firm mattress that supports the whole spine helps. Replace pillows that have lost shape. If you wake with a stiff neck repeatedly, review your pillow and your day-time posture.
Key points to remember
Neck strains are common and usually settle within weeks with gentle movement, heat or cold, simple pain relief and attention to posture. Avoid collars and prolonged rest, and seek help for red flags or persistent pain. Our physical therapy team can guide your recovery.

Questions about neck muscle strain
These answers are general information and do not replace an examination or individual medical advice.
How long does a pulled neck muscle take to heal?
Usually 1–3 weeks; moderate strains may take 4–6 weeks.
Should I use heat or ice?
Either; heat often relaxes tight muscles, ice may ease acute pain.
Should I wear a neck collar?
Not for more than a day or two; gentle movement promotes recovery.
What is the best sleeping position?
On your back or side, with a pillow that keeps the neck in line with the spine.
When is neck pain serious?
With trauma, fever and stiff neck, severe headache, arm weakness or numbness, or bladder or bowel changes.
Can stress cause neck strain?
Yes. Stress increases muscle tension in the neck and shoulders.
Can I exercise with a strained neck?
Light aerobic activity such as walking is fine; avoid heavy lifting and movements that provoke pain until it settles.
