In this study (An internet survey of 2,596 people with fibromyalgia) they had this interesting table with symptoms sorted by intensity during the past week: 1. Morning stiffness 2. Fatigue 3. Nonrestorative sleep 4. Pain 5. Forgetfulness 6. Concentration 7. Difficulty falling asleep What surprised me is that pain is only fourth in Fibro (and after that the intensity starts to tail of). It would be interesting to see how it would look in ME/CFS. We can only do simpler polls here, but let's give it a try.
