Hi and welcome.
I think there is a list of universities that work on rsd treatments on the rsdhope.org link.
If I remember correctly I think my gp dr said that Columbia University in New York does research too. I am looking in to going there if I can get a ride from my husband.
My rheumatologist told me that there are no doctors that specialize in rsd. Only universities are investigating it. I think it's sad and scary. Well, good luck and hope you feel better soon.
