Ketamine is a powerful drug. From what I have heard and seen it does work well with some and not so well with others. I had a 5 day inpatient tx and unfortunately it did not help me BUT my RSD is not typical. I would definately investigate it further. I dont know where you live but some of us may know of doctors in your area performing the procedure.

Hope this was helpful. If you have any questions feel free to ask
