palpitations, increased heart rate or shortness of breath with exertion or on standing.a drop in blood pressure, feeling dizzy or pale.pain or aches in the muscles, joints or head.problems with thinking, concentrating, memory loss, vision, clumsiness, muscle twitching or tingling (sometimes called вЂneurocognitive problemsвЂ™).For example, a short stroll, coffee with a friend, getting their child ready for school or catching the train to work, which caused no fatigue before, is followed by unusual tiredness that takes longer than usual to go away.Д«ecause ME/CFSВ is a very complex, multi-system, chronic illness, many other symptoms will occur and must be present for diagnosis. Depending on the amount and type of exercise, it may result in post-exertional malaise for a few days, or serious relapses lasting weeks, months or even years.People with ME/CFSВ find that activities they once took for granted take an enormous toll on their health. The response may be delayed, perhaps after 24 hours. This includes abnormal exhaustion after any form of exertion, and a worsening of other symptoms. Research shows that people with ME/CFSВ have a different physiological response to activity or exercise from other people. This means having flu-like symptoms after exercise and not having enough energy for daily activities. The main feature of ME/CFSВ is a type of exhaustion known as post-exertional malaise, вЂcrashвЂ™ or вЂpaybackвЂ™. Another 25 per cent will experience severe ME/CFS and have to stay at home or in bed. About 50 per cent will have a moderate to severe form of ME/CFS and not be able to get to school or work. An individual management plan must be developed for each person with ME/CFS.ДЄround 25 per cent of people with ME/CFSВ will have a mild form and be able to get to school or work either part-time or fulltime, while reducing other activities. Applying a particular treatment for one subtype can be very damaging to another subtype. In other people, ME/CFS may develop slowly over months or years.There are many subtypes within the spectrum of ME/CFS, which means that a management plan must be developed for each person with the condition. For some people, the condition may be triggered suddenly by a viral infection, toxic exposure, anaesthetic, immunisation, gastroenteritis or trauma. ME/CFS is a complex illness and we do not know the cause.

The term вЂmyalgic encephalomyelitisвЂ™В means pain in the muscles, and inflammation in the brain and spinal cord. It can occur at any age and can affect children as well as adults. Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME),В is an illness that affects a personвЂ™s nervous system (commonly called a вЂneurological illnessвЂ™).
