Do I Have ME/CFS?

Almost everyone experiences fatigue from time to time, but for at least one million U.S. adults, teens and children, the fatigue is crushing, unrelieved by rest and accompanied by a constellation of other punishing symptoms. They suffer from Myalgic Encephalomyelitis (ME) also called Chronic Fatigue Syndrome (CFS). ME/CFS is a debilitating and real medical condition that has a serious impact on a person’s quality of life. Early diagnosis of ME/CFS is important.

If this sounds like you and you’ve been searching for answers, this “Do I Have ME/CFS“ quiz can help you determine if you have symptoms characteristic of ME/CFS. It’s important to remember that this is just a screening quiz and does not substitute for a clinical examination by a health care provider. The only way ME/CFS can be diagnosed is with an extensive health history, a thorough physical examination, exclusion of other possible sources of symptoms and consideration of all the symptoms you are experiencing.

This quiz was designed to assess how well your symptoms fit with the hallmark symptoms of ME/CFS and give you some more information to discuss with your doctor. It should not discourage you from seeking medical attention for diagnosis and care. If you have already been diagnosed by a health care professional it should not substitute for that assessment.

Do I have ME/CFS?

Post-exertional malaise is a hallmark of ME/CFS. Mild exertion or even normal activity results in loss of physical and mental stamina and worsening of other symptoms. Post-exertional malaise can occur immediately or be delayed for 24 hours or more after exertion.

Do you experience post-exertional malaise after physical or mental exertion or normal daily activities?

Severe, debilitating fatigue along with other symptoms must be present for at least six months in adults or three months in children.

Have you experienced at least 6 months of severe physical or mental fatigue that you cannot explain, is not a result of ongoing exertion, is not relieved by rest and substantially reduces your activity levels?

In addition to severe fatigue and post-exertion malaise, ME/CFS patients experience other symptoms. These symptoms may vary from day to day or during the day.

Have you experienced any of the following symptoms during the past 6 months? (check all that apply)

Some conditions commonly occur along with ME/CFS. These include:


•Fibromyalgia (FM)

•Irritable bowel syndrome (IBS)

•Multiple chemical sensitivities (MCS)
