I had 4 day high dose ketamine infusion with Dr. Kirkpatrick. My friend who has full body was there two weeks before me. Within one week of having 200mgs and hour for the last 2 days our RSD returned completely within 2 weeks. My friend is only 32. She just got out of ICU for 5 days because of the pain. This does work for some, but not all. If you go, be sure you take someone who can keep you totally grounded durning the treatment. Someone who totally trust. You must have no one around that causes you any stress at all. I hope this helps. your friend hear4
