Myalgia means "muscle pain" and is a symptom of many diseases and disorders. The most common cause for myalgia is either 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 stress[1]. However, myalgia can also be caused by diseases, disorders, medications, as a response to vaccination and withdrawal syndromes.
Overuse of a muscle is using it too much, too soon and/or too often. [1] Examples are:
The most common causes of myalgia by injury are: sprains and strain (injury)[1].

A moderate occurrence (25-35%) of myalgia in recipients of tetanus vaccination is identified in the US; it presents in the large muscle groups and at the subcutaneous injection site. When a patient returns with these symptoms (which include fever, poor appetite and lethargy), a clinician who fails to notice the recent tetanus vaccination on the patient's chart is in danger of making a life-threatening misdiagnosis.
- An item of note is that in heart patients using selective β1-blockers such as metoprolol, incidence of myalgia after tetanus vaccination is significantly higher.
Sudden cessation of opioids, barbiturates, benzodiazepines, or alcohol can induce myalgia.
