Hey Roger:
Don't worry needlessly about reaction to Vidaza. I'm currently taking Vidaza treatments at the VA in Fayetteville, Arkansas with 7 others receiving the same treatment. All are tolerating it well. Only one person is not responding to the drug.
For the details of my experience see
my experience with Vidaza.
I took three of the double-shots of Vidaza in the upper arm and two in the stomach. One of the double stomach shots turned into a large, knotted bruse. From now on I intend to take all shots in the upper arm.
