Please be careful with any treatment regarding CRPS. Much of it is outdated. The most up to date therapies and treatments regarding both types of CRPS and all presenting forms, progressive, regressing, peripheral presentation in hand or foot, neck, shoulder, back, or origination of injury is not found within the United States but Europe.
The only tap to that source I have found is The Reflex Sympathetic Dystrophy Syndrome Association’s Website http://www.rsds.org. Others attempt to stay up to date with Europe’s strides with CRPS and RSD but they are woefully behind the eight ball INCLUDING our CDC, FDA, DEA, NIH, and the WHO.
