Ron:
I wish there was something I could say to alleviate your fears, but the reality is you have every right to feel that human emotion right now.
It would be easy to say "trust the doctors and surgeons", but from your own personal health issues and experience you know that medical personnel are not infallible and it is why their work is called a "practice", as much as I disdain the concept because it makes me feel like I am a "Guiney Pig".
I just wanted to let you know that there are many Autopians who are hoping and praying for you during this time and that you are not alone, even as I have said before, I have never met you personally. I cannot reiterate about the importance of those individuals close-bye physically that have taken the time to visit with you and help you out. They are far more than friends or acquaintances.
Keep us informed.
