CHRONIC FATIGUE SYNDROME: SIGNS AND
SYMPTOMS
Chronic Fatigue Syndrome: Signs and Symptoms
By: Cherish Hamutoff


Although anyone can develop Chronic Fatigue Syndrome (CFS), it is more commonly found in adults ages
40 to 59, women and low-income persons. Experts estimate that around one million Americans suffer from
CFS, however less than 20 percent of estimated cases are diagnosed.

CFS is very difficult to diagnose because the symptoms are common in other illnesses and medical side
effects, and there is no lab test to confirm the diagnosis. Signs also vary from person to person and range
from mild to serious.

Chronic Fatigue Syndrome may come on suddenly or develop gradually over time. CFS causes people to
feel completely drained of energy and extremely tired. Some people get tired over a period of days or
months, while others get tired suddenly overnight. This excessive tiredness makes simple everyday tasks
like eating, waking, dressing and moving very challenging. The tiredness isn’t cured by sleep or rest.

CFS can cause trouble focusing, muscle pain or sleeplessness. Tiredness may come and go, and in certain
cases, never leave. Diagnosis isn’t made until after six months of extreme tiredness.

The Main Signs of Chronic Fatigue Syndrome
Extreme weakness and tiredness
Inability to recover more than 24 hours after exercise (physical or mental)
Flulike symptoms
Lack of focus and forgetfulness
Waking up tired
Muscle aches or pain
Joint aches or pain without visible redness or swelling
Sore throat
Tenderness in the neck or arm lymph nodes
New types of headaches

Secondary Signs of Chronic Fatigue Syndrome
Personality changes; including anxiety, irritability, panic attacks, mood swings
Changes in vision; including eye pain, light sensitivity, blurring
Irritable bowel
Night sweats and chills
Drop in body temperature or low grade fever
Changes in sensitivities or allergies
Numbing or burning of the hands, feet or face
Loss of balance, dizziness or fainting

Why some people develop CFS is still a mystery to medical professionals. Some develop it after a minor
infection (mononucleosis, stomach bug or cold), while others develop it during an extremely stressful time.
Medical treatments and illness can cause extreme tiredness, so it’s difficult to diagnose if the tiredness is
from CFS or other factors.
