Muscle pain, also known as Myalgia, is a common condition that can result from overuse, injury, stress, or underlying health issues. It may affect one or multiple muscle groups and can range from mild discomfort to severe pain. Common causes include physical strain, dehydration, and infections. Treatment often involves rest, hydration, and gentle stretching. In some cases, muscle relaxant or physical therapy may be recommended. Seeking medical advice is important if the pain persists or worsens over time.
