I have several Ideas for you to find out about Ketamine infusions. If you have a teaching hospital, contact the patients advocacy person. Also on the internet, there may be a contact for American Medical Association. There also may be help through your local library to find resources. I can't believe your state would not have this type of medicine available to you.
I had two ketamine infusions in my neck which did help. Different problem, but I did get some relief before my spinal fusions. I wish you all the best. ginnie
