Symptoms of CFS
Primary Symptoms
Although its name trivializes the illness
as little more than mere tiredness, chronic fatigue syndrome (CFS)—also known as
chronic fatigue and immune dysfunction syndrome (CFIDS)—brings with it a
constellation of debilitating symptoms.
As the name chronic fatigue syndrome
suggests, this illness is accompanied by fatigue. However, it's
not the kind of fatigue we experience after a particularly busy day or
week, a sleepless night or stressful events. It's a severe, incapacitating fatigue that
isn't improved by bed rest and that may be worsened by physical or mental
activity.
The fatigue of CFS is accompanied by
characteristic symptoms lasting at least six months. These symptoms
include:
- postexertional malaise (extreme
exhaustion and worsening of symptoms following physical or mental
activity)
- difficulties with memory and
concentration
- problems with sleep (unrefreshing
sleep)
- persistent muscle pain
- multijoint pain without redness or
swelling
- headaches
- tender lymph nodes
- sore throat
The symptoms of CFS are
highly variable and fluctuate in severity, complicating treatment and the patient's
ability to cope with the illness. Most symptoms are invisible, which makes
it difficult for others to understand the array of debilitating symptoms, or their
impact.
It's important to tell your health care
professional if you're experiencing the symptoms of CFS. They may be related to
CFS, or they may indicate that you have another treatable disorder. Only a
health care professional can diagnose CFS.
Other Common Symptoms People with CFS also report many additional symptoms, such as
word-finding difficulties, inability to comprehend/retain what is read,
inability to calculate numbers and impairment of speech and/or reasoning. CFS
patients may also have visual disturbances (blurring, sensitivity to light, eye
pain, need for frequent prescription changes); psychological problems
(depression, irritability, anxiety, panic attacks, personality changes, mood
swings); chills and night sweats; shortness of breath; dizziness and balance
problems; sensitivity to heat and/or cold; alcohol intolerance; irregular
heartbeat; irritable bowel (abdominal pain, diarrhea, constipation, intestinal
gas); low-grade fever or low body temperature; numbness, tingling and/or burning
sensations in the face or extremities; dryness of the mouth and eyes (sicca
syndrome); gynecological problems including PMS and endometriosis; chest pains;
rashes; ringing in the ears (tinnitus); allergies and sensitivities to
noise/sound, odors, chemicals and medications; weight changes without changes in
diet; light-headedness; mental fogginess; fainting; muscle twitching; and
seizures.
