Symptoms and Diagnosis
Symptoms of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) may appear similar to many other illnesses and there is no test to confirm ME/CFS. This makes ME/CFS difficult to diagnose. The illness can be unpredictable. Symptoms may come and go, or there may be changes in how bad they are over time.
A doctor should be able to distinguish ME/CFS from other illnesses by doing a thorough medical exam. This includes asking many questions about the patient’s health history and current illness and asking about the symptoms to learn how often they occur, how bad they are, and how long they have lasted. It is also important for doctors to talk with patients about how the symptoms affect their lives.
