Dr. Hooshmand has retired
But I agree with ADA, read and learn and compare with newer studies.
I learn't a lot from his puzzle's when i was frist DX'd in 2001, even took a look at his side with my own neurologist. He learned alot, and thanked me

I also have his book
IASP(International Associsiation(SPL) of the study of Pain), has some book's too about RSD /CRPS, if you want to read more.
