I used to love the cold
These days my body literally can't regulate itself in the cold.
My hands can't function properly, my breathing gets shallow, I shiver, have shortness of breath. It could happen from being in the freezer section of the grocery store for 10 minutes or being in temps of under 64 degrees. If I don't get out of the situation fast enough, my hands up to my elbows get numb. It's like my body can't circulate blood already, and when I get cold or even slightly cool, it shuts down.

What is up with that?
Happen to anyone else?
