Hello - I'm not sure I totally understand your question however I am sorry you have suffered so much with this. In my experience there is often an overlap between central sensitization and other chronic illness. So for instance, 30% of people with Rheumatoid Arthrtiis have fibromyalgia. Which means ,they have joint pain and fatigue even when there is no active RA. So it's never wrong to try a pacing approach to see if it helps. Good luck! (cfsselfhelp.org)
