I hate to say it, but that is the beauty of Thyrogen! At least the medical community has come up with an alternative. The problem is that it will take a long time for all of the endos to adopt a new method. Many are afraid of new medical techniques. Luckily my endo participated in a seminar put on by Sloan Kettering the weekend before I started treatments. It was my saviour because I insisted on Thyrogen. I'm glad I did.
You're right, they have never been through it so it's easy for them to say it's nothing. My endo originally told me "You're young so you'll be fine. You and your body can take it with no problem". I'm 54 years old. I did like the young part! :O
I still say all doctors should be required to sign on to a message board like this and learn what REALLY goes on!!
I hope it gets better for you!
