Ketamine
"I have M.S and a syrinx, have had neuropathic pain for 17 yrs. Neurontin being the only thing that helped, but even it didn't remove much of the pain.  I have now had Ketamine twice. The first time was I.V. It removed 90% of my neuroppathic pain and lasted for about 8 months. When the pain came back I was shocked at how bad it was.  I have just finished my 2nd dose this time I was given it subcutaneously.  I have only the smallest amount of neuropathic pain left. The whole thing went very well so now when the pain is back I will go back and have another infusion. This time I only have a very small amount of pain left. I feel this has been the biggest thing that has helped my quality of life. I wouldn't hesitate to recommend it to others."
