This is a highly personal choice and I hesitate to comment. I am in the process of getting a scs implanted. After spending countless hours researching both devices on professional sites and patient driven web boards, I decided to go with the scs because I felt that a failed scs was less dangerous than a failed pump. That was MY conclusion and may be totally incorrect. My problem is that the majority of luck that I have had with my pain issues for the last 30 years has been bad luck so I went with the scs based on personal fear. There are numerous folks here that have tremendous relief from their pumps and wouldn't dream of going another direction. I congratualate them on their success and relief. I hope they will jump in and tell you THEIR story. Best wishes for great results with your choice.
