Muscle or body aches refer to discomfort or pain in the muscles or throughout the body. This sensation can result from various factors, including physical activity, injury, or illness. Common causes include exercise, viral infections, and chronic conditions like fibromyalgia. These aches can vary in intensity and may be accompanied by other symptoms, such as fatigue or stiffness. While often temporary, persistent or severe aches may require medical attention to identify underlying issues. Treatment options typically include rest, over-the-counter pain relievers, and gentle stretching or physical therapy.
