From Wikipedia, the free encyclopedia
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.
[edit] Causes
The most common causes of myalgia are overuse, injury or stress.[1] However, myalgia can also be caused by diseases, disorders, medications, as a response to vaccination and withdrawal syndromes.[citation needed]
[edit] Overuse
Overuse of a muscle is using it too much, too soon and/or too often.[1] Examples are:
[edit] Injury
The most common causes of myalgia by injury are: sprains and strain (injury).[1]
