Hi Lauren,
I'm with you, feeling feverish with a low body temp is pretty normal for me, and yep, the endo and the rheumy just look at me, but I've noticed that my temperature goes from 96.0 to 98.0/99.0 at the height of the day and it goes back down to 96.0 at the end of the day. Very strange indeed.
It's strange that you never go above 100.00 even when your very sick, I can go from 96.0 to 100.0 in almost a heartbeat - it's no wonder I feel so drained when I first get sick. I have gone to 103.8 and let me tell you, scared the heck out of me (this was the last time I had a sinus infection).
I also have Hashimoto's , so which AI causes it? The endo sends me to the rheumy, the rheumy sends me back to the endo - and these doctors wonder why I often hit my head on a brick wall. But I'm glad to see you up and about tonight!
Take care -
Patze
