Dianne, Rob,
Thanks a lot for the information.
I am seeing my endo in a few weeks and I will ask him to write me a script for the lab for thyroid hormones (especially T3) so I can have blood drawn on-the-spot the next time I have a migraine and this low temp. It makes sense to me that if there’s a low level of T3 when I’m sick, they can compare that to the blood draws I have had in the past when I am well and determine if the difference is significant and whether or not it could be causing the symptoms.
The doc may not go for it, I know, and I might be barking up the wrong tree, but I figure it’s not that hard or expensive to have some blood drawn and see what’s what. An intermittent low T3 might well be to blame. I have read that T3 has a short half-life – perhaps the blood level is low when I’m suffering and then back to normal in a number of hours.
