Myalgia, also known as muscle pain or muscle ache, is a symptom that presents with a large array of diseases. While the most common cause is the overuse of a muscle or group of muscles, acute myalgia may also be due to viral infections, especially in the absence of a traumatic history. Longer-term myalgias may be indicative of a metabolic myopathy, some nutritional deficiencies, or chronic fatigue syndrome.
|Other names||Muscle pain, muscle ache|
The most common causes of myalgia are overuse, injury, or strain. However, myalgia can also be caused by diseases, medications, or as a response to a vaccination. Dehydration at times results in muscle pain as well, for people involved in extensive physical activities such as workout. 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:
- Ehlers-Danlos syndrome
- Auto-immune disorders, including:
- Infections, including:
Overuse of a muscle is using it too much, too soon or too often. Examples are:
- Multiple sclerosis (neurologic pain interpreted as muscular)
- Myalgic Encephalomyelitis (chronic fatigue syndrome)
- Mixed connective tissue disease

- Fibromyalgia syndrome
- Familial Mediterranean fever
- Polyarteritis nodosa
- Devic's disease
- Carnitine palmitoyltransferase II deficiency
- Conn's syndrome
- Adrenal insufficiency
- Postorgasmic illness syndrome
- Chronic fatigue syndrome
- Ehlers Danlos Syndrome
- Stickler Syndrome
- Exercise intolerance
- Peripheral neuropathy
- Eosinophilia myalgia syndrome
- Barcoo Fever
- Delayed onset muscle soreness
- Tumor-induced osteomalacia
