Myalgic Encephalomyelitis (M.E.) is an illness with many names. Within the NHS it is commonly called Chronic Fatigue Syndrome (CFS or CFS/M.E.). Sometimes it is known as Myalgic Encephalopathy or diagnosed as Post Viral Fatigue Syndrome (PVFS).
M.E. is a long-term (chronic) fluctuating illness that causes symptoms affecting many body systems, more commonly the nervous and immune systems.
Many people with M.E. experience persistent fatigue or pain. However, M.E. is characterised by a range of additional symptoms.
See NHS guidelines.
