A trapezius strain occurs when the muscle fibers in the upper back are overstretched or torn, often due to sudden movements, overuse, or poor posture. This strain can cause pain, stiffness, and reduced mobility in the shoulders and neck. While mild cases may resolve with rest and stretching, more severe strains may require physical therapy or other treatments to promote healing and prevent further injury.
