Myalgia

Myalgia

[mahy-al-jee-uh, -juh]
Myalgia means "muscle pain" and is a symptom of many diseases and disorders. The most common causes are overuse or over-stretching of a muscle or group of muscles. Myalgia without a traumatic history is often due to viral infections. Longer-term myalgias may be indicative of a metabolic myopathy, some nutritional deficiencies or chronic fatigue syndrome.

Causes

The most common causes of myalgia are overuse, injury or stress. However, myalgia can also be caused by diseases, disorders, medications, as a response to vaccination and withdrawal syndromes. It is also a sign of acute rejection after heart transplant surgery.

Overuse

Overuse of a muscle is using it too much, too soon and/or too often. Examples are:
