Rotator Cuff Injury – Symptoms & Causes

Swelling

When an injury occurs, the body activates the immune system to prevent an infection in the affected area. As a result, inflammation might occur and cause swelling. People with a rotator cuff injury might notice the shoulder become larger than usual. When touching, it is often tender and warm as well. Also, swelling might be the result of the increased movement of white blood cells and fluids to the injured area. [2]
