Epidemic myalgia: Also known as Bornholm disease, this is a temporary illness that is a result of virus infection. The disease features fever and abdominal and chest pains with headache. The chest pain is typically worsened by breathing or coughing. The illness usually lasts from 3 to 14 days.
The most common virus causing Bornholm disease is an enterovirus called Coxsackie B.
Bornholm disease is also called pleurodynia (because of inflammation of the lining tissue of the lungs).
