Hi Flavio,
I do hope that things are improving for your wife. It is wonderful that she had such early diagnosis as this makes the chance of remission/cure great as long as treatment is carried out as soon as possible by a Specialist Pain team.
I have actually had some discussions with a physiotherapist who is a member of a team which appears to successfully treat CRPS/RSD in Brazil.
The "noigroup.com" and "somasimple.com" websites have a couple of regular members from Brazil also, it might be a good idea if you can make contact via these sites as they will probably be able to direct you in the direction of the specialists.
Wishing you luck
Tayla
