Hello, and I am glad to hear you are thinking about options. Before I had my last cervical fusion, I had two Katemine infussions in my cervical spine two weeks apart. I had good pain relief for about three months. the best part was the proceedure didn't hurt me. I really thought running this line up my spine would hurt terrible, but it didn't. I also didn't get any bad side effects. I know others have had different outcomes, mine was good. My pain special, I also liked and trusted, so I guess who you have do it, makes a difference.
I was very frightened, but it turned out good in my case. I wish you all the best. ginnie
