Hi Gina,
The pituitary is attached to the hypothalmus which is the gland which reguates body temperature, in addition we all go through cycles of warmer and cooler, also Lucy's cortisol is very different now than before the surgery.
I am betting once you get some more healing behind you and settled in on the supplement regimen that things will get much better.
It would probably be a good thing to keep a diary during this early period which you could do by posting here and that would keep us informed also.
Best wishes. Scott
