I've been diagnosed with fibromyalgia, a chronic pain disorder. That being said, I also display many symptoms of chronic fatigue syndrome... to the point where I'm seeing a doc about it this week. I've been told the two are very much related; possibly intermeshed in many ways. My chiropractor told me that many people who are diagnosed with fibromyalgia also have chronic fatigue and may not know it. They can go hand-in-hand, but not always, which may be the only reason why they have two names. ?? Not sure. (I've got to be ruled out for mono and pneumonia first because of some other symptoms I'm having, but I'm going to the doc first thing Monday.)

Don't know if this helped. Hope it did.
