I'm answering this not as a medical professional, but as a person who copes with fatigue almost every day through a combination of Fibromyalgia, Chronic Fatigue Syndrome, and Arthritis. The fatigue that I (and many, many other people) experience is closely akin to that experienced during a bad case of the flu or other infection: weakness, exhaustion, loss of the ability to move quickly and easily (muscle fatigue), and the inability to think clearly ("the fog") at times. With this type of fatigue, you literally may not be able to stand for long periods of time, or you will fall. Talking may be difficult. Muscles may tremble or shake. This type of fatigue is also not "cured" by rest, although rest helps.
Again, this is the type of fatigue experienced, more or less, by those with diseases such as rheumatoid arthritis, lupus, MS, certain cancers, lyme disease, infections, etc.
In conjunction with the type of fatigue that I'm describing, a person may experience even more fatigue from the stress caused by mental anguish, fear of the future (because of physical inability or the inability to make a living), rejection by society or spouse, social isolation, depression, worry about paying for treatments or finding a Doctor Who will treat the illness. The person may lose the ability to exercise or pursue once-meaningful crafts or hobbies, and this may increase his/her stress or fatigue.
I hope this has helped you.
