Body Temperature

I seem to have less control over my body temperature.  I'm feeling more like my third grade teacher described as an amphibian--a cold-blooded animal that's body temperature is affected by the temperature.  When I'm in the heat, I get immediately overheated (with MS symptoms to boot) and it takes a long time to cool off.  This recently happened when I was out on a relatively cool day doing yard work.  When I came inside, I was nearly blind, had tremors, and was weak and nauseous.  My husband immediately came out with ice packs and placed them all over my body.  I ran a temperature for the rest of the day.

Same thing about the cold--when I get that way it is difficult to get me warm.  In the winter, it's not uncommon for me to have a 96 degree temperature in the evenings.  I will get into a warm bath, my snow white feet and hands will turn a bright red.  Then, I start feeling normal again.  I can't stay in a warm bath, however, because I will get overheated . . .

Anyway, I'm wondering if anyone else experiences this.  I looked up these symptoms online and saw that it can be connected to the hypothalamus, which is in the brain.  This gets me thinking--do lesions ever occur there?

Deb,
I hadn't thought of myself as an amphibian, but you are absolutely right with the concept.
I don't know about lesions on the hypothalamus - perhaps someone else will know.

my best,
