Muscle pain is most frequently related to tension, overuse, or muscle injury from exercise or physically demanding work. Muscle aches and pains are common and can involve more than one muscle at the same time. Muscle pain can also involve the soft tissues that surround muscles. These structures, which are often referred to as connective tissues, include ligaments, tendons, and fascia (thick bands of tendons).
