Your muscles help you move and keep you standing, walking, and running. But sometimes muscles or groups of muscles can hurt. This is called myalgia. Muscle injuries or overuse are the most common causes of myalgia. Certain medical conditions or infections like the flu also can cause muscles to ache. Resting the muscles will usually make the pain go away.
