Malaise and fatigue
Malaise is a general state of the body which is described as feeling of discomfort, getting tired easily, or illness. Fatigue refers to lessened ability to work which is a result of excessive physical or mental effort or which is a consequence of increased energy expenditure e.g. while being ill. It emerges when the body energy reserves are wiped out. It may be a general state of the body or it may be confined to a single organ.
