CFS, also known medically as myalgic encephalomyelitis or ME, is a disease characterised by debilitating fatigue, pain, and other symptoms which are made worse by exertion. The main symptom is chronic fatigue which may last for 6 months, and as at present there is no cure, could turn into a life-long condition.
However, studies have shown that some symptoms can be managed or treated to provide a measure of welcome relief.
