Hi- There is a lot going on with Ketamine and it seems to be helping many people with RSD but not all.  I have an appt next week to meet with a Dr. who is currently doing a 5 day ketamine infusion.  There are only 2 docs in the US that I know of who are doing this now and they have long waiting lists.  If you want any further information just email me at
