A strain is a tear of muscle or tendon fibers. In the neck, it most often happens when the head and neck are forcibly moved — a whiplash-type injury, or contact in sports. Unlike a neck spasm, there’s usually a clear injury moment behind it, though the muscles often spasm as a reaction to the strain itself, so the two can look similar.
Recognizing it
Pain, tenderness, and tight, hard muscles in the neck, worse when moving the head in any direction, sometimes with headaches. A clinician will examine the neck and may order X-rays to confirm the vertebrae themselves weren’t injured.
Early management
Ice for the first 2–3 days, then moist heat often helps more — some people find alternating between the two works best. A short course of anti-inflammatory medication, and occasionally a soft neck collar for support, may be recommended. Most people recover within a few days to a few weeks, though some take longer.
Rehab progression (only if there’s no pain or numbness running down the arm)
- Range of motion: gentle neck rotation, side bending, flexion, and extension, moving only to the point of mild discomfort, not through sharp pain.
- Upper trapezius and scalene stretches: tilting the head away from the tight side while anchoring the opposite shoulder, held 15–30 seconds.
- Isometrics: pressing the head gently against your own hand in each direction to rebuild strength without moving the neck.
- Head lifts: once the above feel comfortable, gentle head curls and side lifts to restore full control.
Before returning to contact sport, you need full, pain-free range of motion — looking fully over each shoulder, chin to chest, head back, and ear to each shoulder — with no burning, spasm, or pain triggered by any of these movements.
