byates,
I have RSD/CRPS also. It isn't technically full body because it does not affect my legs but it affects everywhere else in my body. I have had three rounds of ketamine treatments--each one a five day course. The first treatment decreased my pain about 25% and lasted for about 2 weeks. The second decreased my pain by about 50% but lasted for less than a week. The third treatment did not help at all even though it was a higher dose. I elected not to have any more beyond that because of the ineffectiveness, the high cost (my insurance did not cover it) and the side effects. Even though I personally did not have a good outcome from it, I have heard of many people who have. In my opinion it is definitely worth a try.
I'm sorry to hear your daughter is going through this at such a young age.
