I too am a child of the 60's. I can relate to you. The isotope test is one I would not want eithor. It goes against what I think should be put into my body. I would have a strong reaction against it, if it were ever requested of me. I am against the neuclear things all but in the most serious of conditions. Seed plants and such, I would have a problem with that too. The test they wanted me to do that I didn't want, was to put needles in me and then turn on the electricity. No thank you, I am not a cow, and do not need cattle prods. I considered that test a kind of torture, and I don't react too well to the pain I already have!
I have known two people now both in their 80's and did that stress test. Neithor recovered well. It took months for them to feel better. It makes me wonder for sure just what that isotope does to a person. I have had so many x-rays, MRI'S and CT scans, I had the dentist protect my neck since I have thyroid nodes now. Who knows what caused them. I think it was due to all the exposure I had of my cervical spine, and too many of these tests.
Lately, I do the research like you do, into everything that is asked of me, including all my medications. I have been called a problem patient because I guestion all tests and proceedures. I want to be informed like you do. Sorry you had to go through the stress test at all. ginnie
