Acute soreness, often referred to as muscle soreness, typically occurs after intense physical activity or exercise. This type of soreness is a result of microscopic damage to muscle fibers, leading to inflammation and discomfort. It usually appears within 24 hours of the activity and can last for a few days. The sensation of acute soreness is often described as a dull ache or stiffness in the affected muscles. It is a normal response to increased physical exertion and can be managed with rest, hydration, and gentle stretching. In some cases, over-the-counter pain relief medications may also be used to alleviate discomfort.
