Hi and welcome to the board. I know how scary and confusing this and finding the right treatment. I have been to a few PM docs and all have said to different things. Anyhow I too wonder what you have tried before this. Are you on any meds?I have not had the kentamine though one PM suggested it. I had read that there are different ways of doing it and to get the best benefit. Hang in there and maybe do a search on that on the board to see experiences.
