Hi I am scheduled to have disc replacement surgery on March 19th. My first surgery. I have been experiencing pain for well over a year now, neck, down arm, fingers, weakness in arm as well. My doctor will be using the Prodisc C, he was going to use the Secure C ADR but now has decided because of a conflict in "size" he will again be using prodisc. Needless to say I am scared to death of all of it... I am a Breast Cancer survivor, 6 years now and though very scary we got it at an early stage and all went well. I am concerned about the metals in the device, the length of time this procedure has been used, if I will feel worse afterwards and so on. I haven't found anyone else on this site in my situation or maybe I am not looking in the right area, although I think I have done some searching. If anyone has any helpful information that would be wonderful. Thanks for your time.
