The tiredness limits most treatment, doesn't it? If the person also seems to have fibromyalgia with the CFS, then a general exercise programme helps. Apparently altered sleep patterns/ sleeping problems are part of the cause of the pain, and exercise helps there patients sleep better, which reduces the pain. I didn't get this info from a text book- the best info I've found has come from the Fibromyalgia Support Group (I'm sure they'd have a web site).
