Cold all the time

I'm cold a lot, my fingers get extremely cold to the point of being numb and tingly.  My VSG doctor suggested I have my thyroid check.  Well my PCP checked my thyroid, iron, vitamin d & b12 all normal.  Any thoughts, I'm over 2 years out.

When you get the answer to this, I would love to know myself. I am freezing!!!!

My hands are always freezing...I love touching people and seeing them jump lol.

We no longer have any fat to keep us warm!  My feet are the worst.  I've invested in those really thick wool socks.  I even wear them to bed.
