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.

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[2] and withdrawal syndromes.[citation needed] It is also a sign of acute rejection after heart transplant surgery.

The most common causes are:

  • Injury or trauma including sprains and strains
  • Overuse: using a muscle too much, too soon, too often
  • Tension or stress

Muscle pain may also be due to:

  • Certain drugs, including:
    • ACE inhibitors for lowering blood pressure
    • Cocaine
    • Statins for lowering cholesterol
  • Dermatomyositis
  • Electrolyte imbalances like too little potassium or calcium
  • Fibromyalgia
  • Infections, including:
    • Influenza (the flu)
    • Lyme disease
    • Malaria
    • Muscle abscess
    • Polio
    • Rocky Mountain spotted fever
    • Trichinosis (roundworm)
  • Lupus
  • Polymyalgia rheumatica
  • Polymyositis
  • Rhabdomyolysis
