Muscle pain, also known as myalgia, refers to discomfort or soreness in the muscles. It can result from various factors, including overuse, injury, or strain during physical activities. Common causes include exercise, muscle cramps, and tension from stress. In some cases, muscle pain may be a symptom of an underlying condition, such as fibromyalgia or infections. Treatment often involves rest, ice, and over-the-counter pain relievers. Maintaining proper hydration and stretching can help prevent muscle pain and promote overall muscle health.
