Lit,
My dad at 72 had both chemo and radiation when he was diagnosed with colon cancer. He lived cancer free until he died in his late 80's.

I won't give "you need or you should" messages, because I think there is no message for this. I vividly recall the numbness I felt when I was told that I needed brain surgery.

I know the fear and the worry you have about average medical procedures. I am insane with anxiety before my brain angiograms. My most recent one was last week. I have been in CRPS related pain ever since.

I find it helps me feel in control if I request accomodations like pediatric needles and I remind everyone that I have CRPS. I think the next time I will bring a decorated "fall risk and CRPS" sign with me.
