Muscle ache
Other names: Muscle pain, myalgia[1]

Muscle ache, also known as myalgia, is pain in muscle.[1] It is a feature of muscle tension, overuse, or injury from physical work and exercise.[1] It may present as a symptom of an infectious disease and other diseases such as lupus and fibromyalgia.[1]


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, especially for people involved in extensive physical activities such as workout. It is also a sign of acute rejection after heart transplant surgery.[citation needed]

Long-lasting myalgia can be caused by metabolic myopathy, some nutritional deficiencies, and chronic fatigue syndrome. The most common causes are:[citation needed]

  • 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:


Overuse of a muscle is using it too much, too soon or too often.[5] One example is repetitive strain injury. See also:


The most common causes of myalgia by injury are: sprains and strains.[5]


Metabolic defect


Withdrawal syndrome from certain drugs

Sudden cessation of high-dose corticosteroids, opioids, barbiturates, benzodiazepines, caffeine, or alcohol can induce myalgia.[citation needed]


When the cause of myalgia is unknown, it should be treated symptomatically. Common treatments include heat, rest, paracetamol, NSAIDs and muscle relaxants.[7]
