I had ketamine for spinal problems. It did provide releif. I also have developed RSD in my ankles. I would do it again, if this was something my doctor thought would help. I just started developing this from severe injury to ankles that was diagosed incorrectly. Ketamine has worked for alot of folks. I had NO side effects for in infusions, no pain at all, before(shot to numb), during or after. I wish you all the best. ginnie
