My personal opinion is a Neurologist, that is informed about RSD, is the kind of Dr. to see. I see a Neurologist who also is a pharmacologist and a psychiatrist. I've been seeing him for at least 5 years. Once a month, as I have had RSD for 15 years.
RSD is a neurological disorder. It is a autonomic disorder, which means it effects the sympathetic nerve, parasympathetic nerve, involuntary organs which control body temperature, blood pressure, circulation, (that's why HBOT helps some people-it promotes circulation to extremities) Hyperbaric Oxygen Chambers help some people. My Dr. just built two clinics that both have HBOT in them, they also promote healing, burn victims, and other conditions. Insurance doesn't cover HBOT for RSD, so I'm working on getting into a financial position to go thru a series of treatment. It's expensive. There are a couple of people on this forum that have HBOT in their homes. I have personally talked to clinics in Florida and California. I'm about 10-15 minutes from both clinics, here in Scottsdale and Paradise Valley.
Hope this helps, loretta with soft hugs
