Thank so much Odette, I'm glad to know I'm not really such a mystery after all if someone else has had the same thing I have no idea if it would have been caused by a virus, I don't recall being sick in August last year, being poked & prodded for IVF, but not any viruses that I can recall. I'm glad to hear you were allowed to be near the kids after the RAI test, that was my biggest worry, though maybe they did a stronger version for my friend because they were checking if she was still in remission from thyroid cancer.
