Muscle soreness, often referred to as delayed onset muscle soreness (DOMS), typically occurs after intense physical activity or exercise. It is characterized by a feeling of stiffness, tenderness, or pain in the muscles, usually appearing 24 to 72 hours after the activity. This soreness is a normal response to the stress placed on muscles during workouts, especially when trying new exercises or increasing intensity. The soreness results from microscopic damage to muscle fibers, which is part of the body’s natural healing process. As the muscles repair, they become stronger and more resilient. Proper hydration, rest, and gentle stretching can help alleviate discomfort associated with muscle soreness.
