One of the myalgic symptoms

Myalgia or muscle pain is a painful sensation evolving from muscle tissue. It is a symptom of many diseases. The most common cause of acute myalgia is the overuse of a muscle or group of muscles; another likely cause is viral infection, especially when there has been no injury.

Long-lasting myalgia can be caused by metabolic myopathy, some nutritional deficiencies, ME/CFS, fibromyalgia, and amplified musculoskeletal pain syndrome.



The most common causes of myalgia are overuse, injury, and strain. Myalgia might also be caused by allergies, 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.

Muscle pain is also a common symptom in a variety of diseases, including infectious diseases, such as influenza, muscle abscesses, Lyme disease, malaria, trichinosis or poliomyelitis;[1] autoimmune diseases, such as celiac disease, systemic lupus erythematosus, Sjögren's syndrome or polymyositis;[1][2] gastrointestinal diseases, such as non-celiac gluten sensitivity (which can also occur without digestive symptoms) and inflammatory bowel disease (including Crohn's disease and ulcerative colitis).[3]

The most common causes are:[citation needed][4][5] [6]

  • 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.[10] One example is repetitive strain injury. See also:



The most common causes of myalgia by injury are: sprains and strains.[10]



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, massage, cryotherapy and muscle relaxants.[12]
