There are indeed websites that track what works for different people that include non-medical treatments. One of them is called curetogether.com and if you log in there, and type in complex regional pain you'll see a few people have added what works and what doesn't for them (under "Treatments").

If more people used that site, then I'd think you'd get more useful information out of it. No need to reinvent the wheel... I think patientslikeme.com does this too, but not for CRPS.
