Yes, I have cold hands and feet. I do not know if it is related to my thyroid- waiting for some extensive thyroid testing. I have been told when I eat something I am sensitive or allergic to, not enough blood flows to head. It has something to due with cells doubling in size so brain is unable to pick them up right away.
I always thought I had poor circulation in my feet since they are cold, but a foot doctor told my circulation in feet in good.
