A recent troll of Clinicaltrials.gov surprised me with new studies that just started for CRPS. besides neridronate, there is a trial at Stanford for LDN and one starting on oral zolendronate elsewhere. This made me feel like there is at least interest.

A troll of Pubmed with a search term "Complex Regional Pain Syndrome" turns up many, many articles on everything from immune to amino acid differences in CRPS. These are being published all the time. The research community has taken note...

It is only 2015. The century is young. I'm holding out some super genius will bring hope for the future.
