Myalgic encephalomyelitis/chronic fatigue syndrome

Chronic medical condition

Myalgic encephalomyelitis​/​chronic fatigue syndrome (ME/CFS) is a disabling chronic illness. People with ME/CFS experience profound fatigue that does not go away with rest, as well as problems with sleep and memory or concentration. The hallmark symptom is post-exertional malaise (PEM), a worsening of the illness that can start immediately or up to days after even minor physical or mental activity.
