We observe Chronic Fatigue Awareness Month in May every year. It raises awareness about chronic fatigue syndrome (C.F.S.). Some symptoms of C.F.S are fatigue, memory loss, severe exhaustion, brain fog, disturbed sleep, headaches, sudden pain in the muscles or joints, and enlarged lymph nodes. This month informs people about the effects of C.F.S., and there are many ways to spread awareness. Prevention is always better than cure, so let this month be an opportunity for us all to start taking care of ourselves better.

History of Chronic Fatigue Awareness Month

Chronic fatigue syndrome, also known as C.F.S., is a long-term illness that causes severe tiredness and can last six months or more. This illness is hard to diagnose, and the cause has not been successfully linked to any genetic predisposition. Many doctors and health professionals believe that C.F.S. depends on various factors working together as triggers. It is hard diagnosing the syndrome because there is no standard test to confirm if the patient has C.F.S. The diagnosis is made through a series of elimination procedures, and the treatment is also done by testing the symptoms first.
In 1750, Sir Richard Manningham first reported an illness with similar symptoms presented by C.F.S. This syndrome was known as Febricula, which meant “little fever.” Medical journals like the British Medical Journal and The Lancet claimed that this Febricula syndrome was something that even great figures from the past like Florence Nightingale and Charles Darwin suffered from. Their symptoms matched that of the C.F.S. we know today.

In 1988, the full medical term was used in medical journals to describe an illness that resembled the chronic active Epstein-Barr Virus infection or E.B.V. but was not caused due to the virus. In that year, researchers from the U.S. Centers for Disease Control and Prevention found an outbreak of C.F.S. in patients, and since then, the new term was applied.
