What are some symptoms of chronic fatigue syndrome (CFS) and fibromyalgia?

Chronic fatigue syndrome (CFS) and fibromyalgia (FM) are illnesses that often coexist and affect millions of Americans. Symptoms vary amongst individuals and commonly include severe fatigue, sleep disturbances, cognitive problems (commonly called brain fog), muscle pain and multiple infections.

Hallmark symptoms include exhaustion, widespread achiness, brain fog, and insomnia. It is the insomnia that suggests that CFS and fibromyalgia are present as opposed to the causes of fatigue and pain.
