Gina:
I fell off the treadmill so many times that the folks at the gym banned me from the darn thing!
I had the same test you describe and was scared spitless at first. But, when all was said and done, more was said than done. It was nothing at all for me. Albert stayed with me and joked with all the x-ray techs as they were working on me. Our cardiologist came by and stayed to talk with Al, who is also his patient. I even shared a recipe for liver with one of the techs. They even gave me a lollypop when I left.
Perhaps someone can be with your relative while the test is being performed. I'm sure that my positive experience had a great deal to do with the fact that there were familiar people with me during the procedure.
Kind regards,
Blanche
