Hi Cactusfoot, I thought you may be in Arizona due to your 'name' I live in Phoenix. There is a RSD support group here that meets once a month and I believe there is one in Tucson too. You can get the address and times thru RSDSA on line. It was here in Scottsdale at the Mayo Clinic that the Ketamine studies were done with 5=6 Dr. Schwartzman was one of them. A friend of mine worked with them during the studies. Dr. Harbot, Dr. Correll were among the group. This was done maybe 10-12years ago before they went up north and set up practice. I have name of neurologist that diagnosed me and is familiar with RSD. Also my orthopedic dr who was responsible for me getting the use of my frozen left hand back. His physical therapy group were good and experienced with RSD. There is another neurologist here that I've gone too that has his own HBOT equipment in his office. He is expensive and I don't believe takes insurance of any kind.
Take care, loretta
