ME/CFS Hand Pain Adaptations?

Has anybody with ME/CFS found a way for reducing or preventing hand/wrist/arm pain and stiffness? Since it's not really muscle or tendon related, things l have tried (compression gloves, larger handles) have made very minor or zero difference. Any ideas?

I want to be able to write in a notebook, draw or play video games for longer than extremely limited short times or nuking my ability to use that arm for a while afterward. I recognize this may be an unrealistic goal, but I figured I'd ask anyway? I seek the wisdom of the ME collective on this one.
