I am very sorry you are sufferring from this, I all to well know what you are going through as my Mother has had RSD for a long time, and I also live with much pain daily.
Her Rheumatologist suggested Acupuncture, but there are many different opinions, and everyone is different.
Recently while I was seeing my Osteopath, I asked him about RSD.
What he said amazed me, he said that RSD is related to the Parasympathetic and Sympathetic System, and that he can treat it.
He said that basically, it is a more severe case of what I have, Fibromyalgia.
I did not ask him more at that time, but I plan too!
In any case, he is an Osteopath with much experience, and also Holistic Medicine.
I would seek out a 'good' Osteopath, in Holistic Medicine, and see what he can do for you, and please let me know how it goes!
