This document discusses tension neck syndrome, including its definition, symptoms, causes, treatment, and prevention. Neck tension refers to neck pain caused by tight neck muscles that cannot relax, leading to soreness and headaches. Common causes include poor posture, repetitive motions like using phones and computers, teeth grinding, exercise, sleep positions, stress, and trauma. Treatment involves NSAIDs, massage, heat/ice, baths, meditation, yoga, and exercises. Prevention focuses on ergonomics, posture, breaks, sleep, weight distribution, movement, and mindfulness. Most neck tension resolves on its own, but a doctor should be consulted if pain is severe or persists.
