Managing rsd, is an hour to hour ordeal, often.
About the "use it or lose it", we all have delayed pain when we go beyond or normal activity levels. UioLi is not meant that we need to lift weights and jog 20 miles/day!
It simply means, that sometimes you hafto work through the pain and stiffness, and loosen up. I myself wake up in pain, and feel better as the day goes on, (if I'm not being too physical). And, my meds eventually kick in.

As far as Aleve, I merely recomended that to DEW, who was having a bad day on Sunday. It's just as a "change up" strategy. Sometimes, when nothing seems to help for the pain, we've got to change our situ. Weather it be stressors, temperature, (sometimes a hot bath/sometimes a cool shower) positional, humidity, meds not working is what I recomended the Aleve for.
Tylenol and Motrin are both useless to me. Tylenol hurts the liver (the FDA is now calling for a stricter warning for Tylenol), and Motrin just makes me ill.
Aleve seems to be the best choice, for me. (Find which one is best for You!)
And, if my meds aren't cutting it at one time or another, I take two.
And, they often help!
Simple as that really.

Good feelings to All!
