Myalgia means "muscle pain" and is a symptom of many diseases and disorders. The most common causes are the 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.
The most common causes of myalgia are overuse, injury or strain. However, myalgia can also be caused by diseases, disorders, medications, or as a response to a vaccination. It is also a sign of acute rejection after heart transplant surgery.
The most common causes are:
- Injury or trauma, including sprains, hematoma
- Overuse: using a muscle too much, too often, including protecting a separate injury
- Chronic tension
Muscle pain occurs with:
- Rhabdomyolysis, associated with:
- Infections, including:
- Auto-immune disorders, including:
Overuse of a muscle is using it too much, too soon and/or too often. Examples are:
Chronic fatigue syndrome aka Myalgic Encephalomyelitis, Ehlers Danlos Syndrome, Hypokalemia, Exercise intolerance, Mastocytosis, Peripheral neuropathy, Eosinophilia myalgia syndrome, Fibromyalgia, Barcoo Fever, Herpes, Delayed onset muscle soreness, AIDS, HIV, Tumor-induced osteomalacia, Post Orgasmic Illness Syndrome
