Why Does My Neck Hurt on One Side?

One-sided neck pain typically results from muscle strain, poor sleeping position, or nerve irritation. Sleeping in an awkward position causes up to 60% of acute neck pain cases, creating tension in the levator scapulae and upper trapezius muscles. Sudden movements, prolonged computer use, or carrying heavy bags on one shoulder can also strain neck muscles unilaterally. More serious causes include cervical radiculopathy, where compressed nerve roots create sharp, shooting pain down one side of the neck and potentially into the arm. Most one-sided neck pain resolves within 48-72 hours with rest, gentle stretching, and anti-inflammatory medication.
